In PHP 7.x, ereg functions are no longer supported. Based on my search on internet, ereg functions use a very limited regex flavor called POSIX ERE - meaning pref functions can cover more REGEX syntax as designed. |
Below example shows the alternative method in preg functions
ereg functions | recommended alternative functions |
---|
eregi( string $pattern , string $string ) : int Code Block |
---|
$source = "My email address is Chun Kang<ck@qsok.com>.";
if (ereg("email", $source)) {
echo "the source has 'email' on the content";
} |
| preg_match( string $pattern , string $subject ) : int Code Block |

$source = "My email address is Chun Kang<ck@qsok.com>.";
if (preg("/email/", $source)) {
