PHP preg_match regular expression function example

Regular expressions are used in almost all programming languages. This example introduces the application of the regular expression preg_match function in PHP. The

preg_match() function is used for regular expression matching, returning 1 successfully, otherwise returning 0.
preg_match() will stop matching after one successful match. If you want to match all results, you need to use the preg_match_all() function.

Syntax:

Instance:
This instance matches strings with capital letters followed by . and spaces, and can only match J., because preg_match( ) will stop matching after one successful match, and will not match again.

php $str="Daniel J. Gross Catholic High School A. is a faith and family based community committed to developing Christian leaders through educational excellence in the Marianist tradition."; if(preg_match("/[A-Z]. /",$str,$matches)){ print_r($matches); } ?>

Output result:

Array ( [0] => J. )
