PHP attempts to make it easy for developers to write dynamically generated web pages. PHP also offers built-in database integration for several commercial and non-commercial database management systems, so writing a database-enabled webpage with PHP is fairly simple. The most common use of PHP coding is probably as a replacement for CGI scripts. -------------------------------------------------------------------------------- Update Information: **PHP version 7.4.21** (01 Jul 2021) **Core:** * Fixed bug php#81068 (Double free in realpath_cache_clean()).
