How to check a case insensitive substring exists within the given string using a regular expression pattern in PHP | PHP program
We will perform regular expression pattern matching using the preg_match() function, here we checked a case insensitive substring exists in the specified string or not.
<?php
$str = "www.tutorialslink.com";
$pattern = "/tutorialslink/i";
$res = preg_match($pattern, $str);
if ($res == 1)
{
printf("Substring found successfully");
}
else
{
printf("Substring did not find in the string");
}
?>
