Regular Expression

String pattern


Now let write a simple string pattern to search for the space characters in the following string:
$st="PHP is a powerful web programming language";
To search for the space characters, string pattern should be:
$strpat='/ /';

Then by supplying this string pattern as an argument of the preg_match(pattern, string) function. The preg_match(pattern, string) function returns 1 if it found the pattern in the string. It return 0 if the pattern is not found.
Now you see the complete example code as shown below:
<?php
$str="PHP is a powerful web programming language";
$strpat='/ /';
$found=preg_match($strpat,$str);
if($found==1) echo "The space is found.";
else echo "The space is not found.";
?>
