It is JavaScript based and uses XRegExp library for enhanced features. Consult the regular expression documentation or the regular expression solutions to common problems section of this page for examples Regular expressions are used by many text editors, utilities, and programming languages to search and manipulate text based on patterns. Some of these languages, including Perl, Ruby, Awk, and Tcl, have fully integrated regular expressions into the syntax of the core language itself. Others like C, C++, .NET, Java, and Python instead provide access to regular expressions only through libraries. PHP supports regular expressions through the use of the PCRE (Perl Compatible Regular Expressions) library which is enabled in almost all PHP installations. When calling any of the methods below, PHP requires that each pattern starts and ends with the same delimiter to differentiate it from a normal string, with the most common delimiter being the forward slash character JavaScript Syntax (regexp),Perl, PHP PCRE Syntax (preg_*),PHP POSIX Syntax (ereg_*) DESCRIPTION Regular expressions (REs), as defined in POSIX 1003.2, come in two forms: modern REs (roughly those of egrep ; 1003.2 calls these extended REs) and obsolete REs (roughly those of ed(1) ; 1003.2 basic REs) Using PHP preg_match () to Search for Patterns in Strings in PHP. The PHP preg_match () function is used to find a match within strings based on your specified pattern. It has two required parameters: the pattern and the string in which we want to find a match.
