Image creating and manipulating in PHP can be done with multiple libraries, some officially supported by PHP and some made by third parties. A common library, especially for developers new to image libraries, is the GD package. You must include the library you wish to use upon installation of PHP (if it is officially supported), or manually include the library into your scripts.
<?php $x =1; ?> PHP changes type for you on the fly. If you need to be sure it's an integer (Because PHP isn't doing a good job changing the type) then cast it thusly: <?php $y = (int)$x ?>
If you will read typecasting on php, you will know more on this. <?php $str = "10"; $num = (int)$str; ?>
One will put PHP encoding type headers before instructions using HTML language. This is done in order to start the HTML sequence through the PHP header.
PHP, PHP3, and PHTML refer to different versions and contexts of the PHP programming language. PHP is the current and widely used version, while PHP3 is an older version that introduced many features but is no longer supported. PHTML is a file extension typically used for PHP files, indicating that the file contains PHP code, while .php is the more common extension today. In summary, the key differences lie in versioning and file naming conventions.
