The mb_ereg() function is an inbuilt function in PHP that is used for searching a string in the multibyte string by using the regular expression.
Syntax:
mb_ereg($pattern, $string, $matches ): bool
Parameters: The following function has three parameters that are described below.
- $pattern: The regular expression pattern that we used for matching against the multibyte string.
- $string: The string to search for a match.
- $matches: This is the optional parameter that stored the match elements in the array.
Return Values: The mb_ereg() function returns either “true” or “false” depending on whether the regular expression pattern matches the string. If the optional $matches parameter is provided, any matched subpatterns will be stored in the array.
Example 1: The following code demonstrates the mb_ereg() function.
PHP
<?php $subject = "12345This is String"; if(mb_ereg("^[A-Za-z\s]+$", $subject)) { echo "Match found!"; } else { echo "Match not found!"; } ?> |
Output:
Match not found!
Example 2: The following code demonstrates the mb_ereg() function.
PHP
<?php mb_regex_encoding('UTF-8'); $pattern = '[0-9]+[a-zA-Z]+'; $string = '123abc'; if (mb_ereg($pattern, $string)) { echo 'Pattern matched successfully!'; } else { echo 'Pattern did not match.'; } ?> |
Output:
Pattern matched successfully!
