PHP is basically an open-source general purpose scripting language which specifically works best for web development projects. PHP is the most preferable choice for coders because it can be easily embedded into HTML. <\/span><\/p>\n<p><span style=\"font-weight: 400;\">PHP is a recursive acronym for Hypertext Processor. What makes PHP development different than other client-side JavaScript language is that it delivers the embedded HTML file to the client on running the script, but would not provide the underlying code based on PHP. This provides the room and space to coders so they can utilize creative methodologies without letting the user know what\u2019s hidden up there sleeves. <\/span><\/p>\n<p><span style=\"font-weight: 400;\">Some of the most renowned CMS such as WordPress and Magento are also based on PHP.
