How to Use the PHP Is_Numeric() Function

The is_numeric() function in the  PHP programming language is used to evaluate whether a value is a number or numeric string. Numeric strings contain any number of digits, optional signs such as or -, an optional decimal, and an optional exponential. Therefore, 234.5e6 is a valid numeric string. Binary notation and hexadecimal notation are not allowed.   The  is_numeric()  function can be used within an if() statement to treat numbers in one way and non-numbers in another. It returns true or false. Examples of the Is_Numeric() Function For example: ?php if (is_numeric(887)) { echo Yes; } else { echo No; } ? Because 887 is a number, this echos Yes. However: ?php if (is_numeric(cake)) { echo Yes; } else { echo No; } ? Because cake is not a number, this echos No. Similar Functions A similar function, ctype-digit(), also checks for numeric characters, but only for digits—no optional signs, decimals, or exponents allowed. Every character in the string text must be a decimal digit for the return to be true. Otherwise, the function  returns false. Other similar functions include: is_null() – Finds whether a variable is NULLis_float() – Finds whether the type of a variable is floatis_int() – Find whether the type of a variable is integeris_string() – Find whether the type of a variable is stringis_object() – Finds whether a variable is an objectis_array() – Finds whether a variable is an arrayis_bool()  Ã¢â‚¬â€œ Finds out whether a variable is a boolean About PHP PHP is an abbreviation for Hypertext Preprocessor. It is an open-source HTML-friendly scripting language that is  used by website owners to write dynamically generated pages. The code is executed on the server and generates HTML, which is then sent to the client. PHP is a popular server-side language that can be deployed on almost every operating system and platform.

Allegories in Dr. Jekyll and Mr. Hyde Free Essays

Allegories in The Strange Case of Dr. Jekyll and Mr. Hyde The novel The Strange Case of Dr. We will write a custom essay sample on Allegories in Dr. Jekyll and Mr. Hyde or any similar topic only for you Order Now Jekyll and Mr. Hyde has many allegories within. An allegory is a symbol with a deeper meaning. In The Strange Case of Dr. Jekyll and Mr. Hyde, there are many allegories. First, there is the religious allegory of the devil and the lower self as well as the â€Å"hiding† aspect of Hyde. Hyde is also an allegory of human character in general. The city of London, and all of its descriptions written by Robert Lewis Stevenson, is filled with allegories. First, Hyde is a complex allegory because it is arguable what exactly Hyde is supposed to represent. Hyde could be an allegory of the devil himself. Hyde could be a demon inside of Jekyll, sort of like in the Exorcist, that needs to come out but eventually become uncontrollable. Although Dr. Jekyll is described as a nice man who has many friends, but he losses them all when he drinks the potion to become Hyde. Hyde could just be an allegory for a literal part of Dr. Jekyll, which is Stevenson’s statement of saying that every person holds a â€Å"lower self,† that just wait for an opportunity to reveal evil. Also one of the most famous quotes from The Strange Case of Dr. Jekyll and Mr. Hyde, is â€Å"If he shall be Mr. Hide than I shall be Mr. Seek. † This could also mean that Hyde is just a part of Jekyll’s soul that literally hides within. Lastly, Hyde could be an allegory of human character itself. Hyde could be an allegory of the capability that everyone has within. However some people never reveal this capability, but for others, like drug users, it is easier for the evilness to come out. London is also an allegory. Mr. Hyde lives in SoHo, which is described as dark, dingy, and filled with the filth of London, which is why it makes sense that Hyde lives there of all places. SoHo is supposed to represent the capability of evil, and where it is grown. In Victorian England, the poorest of the poor lived in awful slums, some had no choice but to live a life of crime and evil, just to escape their reality. On the other hand, Dr. Jekyll lives in a distinguished and posh neighborhood. This is an allegory for Jekyll’s character, as he is a nice man. However, in Victorian England, many bad things went on behind these closed doors, which is true for Dr. Jekyll. The door in the first chapter is an allegory, as well as all the passageways described, like the one to the laboratory. These passageways and doors are places in-between worlds where most of the events in the novel takes place. The in-between of the worlds is like Dr. Jekyll. He is not a good man, nor is he evil. Jekyll is complex, and struggles with the evil part of his personality. Allegories are abundant in the novel, The Strange Case of Dr. Jekyll and Mr. Hyde.

The Use of Sound in A Passage to India Essay Example For Students

The Use of Sound in A Passage to India Essay Jingle bells, jingle bells, jingle all the way. As we hear this cheery song, we are instantly transported to the wonderful month of December, imagining everything that it brings. The snow falling, the decorating of the Christmas tree, hot chocolate and time spent as a family. All these memories and feelings of joy were brought up by a simple verse of a well known song. It is the power of sound and music that can instantly transport us to different places, situations and times, whether fantasy or real. Movie directors use this same power to their advantage. The noises, sounds and music used in films have all been carefully selected to create particular feelings and subconscious thoughts in the viewers mind. Yet, how is this achieved? What goes into the making of each sound and musical note in a film? To what point does sound enhance a movie and have an impact on its audience? The purpose of this research paper will be to analyze the effects of sound in the movie A Passage to India and learn the process that goes into creating the score for such a film. The first movie with sound was The Jazz Singer in 1927. At the time, many critics felt that this would ruin movies altogether. However, movies were never actually silent. All movies have always had music in order to create further understanding of the overall plot. In Charlie Chaplins City Lights, an energetic and lively song was used during the fight scene, yet a romantic and gentle song is played whenever he sees the blind woman selling flowers. In both cases, music helped define the events. Despite the film being silent, music was an important component. Critics who believed movies would suffer from adding sound were proved wrong. Now, sound is one of the richest sources of meaning in a film. Sound is divided into three primary sections. The human voice or dialogue, sound effects and music. Each division of sound has its own influence throughout the movie. The purpose of the dialogue is to tell a story. The dialogue will express the feelings and intentions of the characters. The actors playing a role need to portray feelings and emotions through their tone of voice and conversation. It is their job to make their body movements and intonation seem natural, not forced. When this is done correctly, the actor creates a true persona rather than an actor playing a role. The speed at which the actors read the script is also influential and essentially considered for each character. When a character has a slow, soft and stuttering voice, the audience will immediately see the personage as weak or as the underdog. When the person speaks incredibly fast and is very opinionated, the viewers will likely see the person as annoying or perhaps even humorous. In the movie, A Passage to India, Dr. Aziz had a voice filled with energy, happiness and excitement. In part, he came across as an innocent man due to his expression. Incredibly, all these effects were caused simply by the tonality of the human voice. The next part to be considered is that of the sound effects used in film. A Passage to India had the distinct and constant noises of crickets and water whenever there was a moment of tranquility and loneliness. There was also the loud noises of animals and undistinguishable talking at the local markets and towns. In the case of A Passage to India, all the additional noises used were synchronous sounds. In terms of sound, to be synchronous is to have the sound match the actual events occurring in the film. Synchronous sounds are used to create a sense of realism in the film. However, asynchronous sounds also have an important role in filmmaking. Asynchronous noises can be used to show an annoyance or to create suspense. In the case of A Passage to India, the echoing noise in the Marabar Caves is the perfect example. Mrs. Moore and Adela both kept hearing the echo of the caves even after it was no longer there. It was used to show the sickening effects of the caves. How Renaissance Began in India EssayThe most common sound in the movie is of the chirping of crickets at a distance and the slow and steady rhythm of calm water. Being sounds of nature, the viewer remains relaxed and entranced by the simple moments of Indian culture. Yet, whenever there has been a moment of clashing culture between the English and the Indian, a loud western orchestra plays which shows how the British have overtaken Indian land. Despite the English having power over the people of India, the growth of the Indian people is shown throughout the movie by slowly adding more typical noises of their culture. At the beginning of the film, the sounds of the town were covered by the orchestra yet towards the end, the noise that the townspeople are making are too hard to ignore. It is at this time that Dr. Aziz is released and the Indians gain victory in a trial that had a decided fate. Sound, music, noise, echo Each one adds to the overall success of a film. Many times, sound is not given the credit it should be. Sound creates subconscious emotions in a person that cannot otherwise be achieved. It adds to the plot of a movie, many times as an additional character. Other times, it sets up the narrative and develops the storyline. A scary film would not be as effective without sounds adding suspense every step of the way. Just as an action movie wouldnt be successful without the loud noises of explosions and gunshots. Yes, the process of post-production is difficult and painstaking but it is necessary. The director spends a great deal of time deciding what to add and omit because without the special consideration of sound, a film would not be complete. The viewers will not enjoy or maybe even understand the movie without the special effects added by the music. Sound is one of the most essential parts of filmmaking. Bibliography: Passage to India.
