Is a widely-used open source general-purpose scripting language that is especially suited for web development and can be embedded into HTML
When PHP parses a file, it looks for opening and closing tags, which are <?php and ?> which tell PHP to start and stop interpreting the code between them.
The type of a variable is not usually set by the programmer; rather, it is decided at runtime by PHP depending on the context in which that variable is used. To forcibly convert a variable to a certain type, either cast the variable or use the settype() function on it. Note that a variable may be evaluated with different values in certain situations, depending on what type it is at the time.
