PHP mb_ereg_search() Function - Coding

The mb_ereg_search() is a PHP function used to search & match for a regular expression pattern in a string using multi-byte characters. It is similar to preg_match() but works with multi-byte characters.

Syntax:

mb_ereg_search(?string $pattern = null, ?string $options = null): bool

Parameters: This function accepts the two parameters that are described below:

pattern: A regular expression pattern search for. It must be a valid regular expression for searching for a specific pattern in the string.
options: This is an optional parameter. A string that specifies the search options.

Return Value: This function returns “true” if the multibyte string matches with a given regular expression otherwise returns “false”.

Example 1: The following code demonstrates the mb_ereg_search() function.

PHP

<?php 
$string = "Hello, world!"; 
     
mb_regex_encoding("UTF-8"); 
mb_ereg_search_init($string); 
     
if (mb_ereg_search("world")) { 
    echo "Found 'world' in the string\n"; 
} 
?>

Output:

Found 'world' in the string

Example 2: The following program demonstrates the mb_ereg_serach() function.

PHP

<?php 
$targetString = "The quick brown fox jumps over the lazy dog."; 
$pattern = "america"; 
  
mb_internal_encoding("UTF-8"); 
mb_ereg_search_init($targetString, $pattern); 
  
  
if (mb_ereg_search()) { 
    echo "The pattern was found in the target string.\n"; 
}  
else { 
    echo "The pattern was not found in the target string.\n"; 
} 
?>

Output:

The pattern was not found in the target string.
