mb_ereg_search_getregs

Function name: mb_ereg_search_getregs()

Applicable version: PHP 4 >= 4.2.0, PHP 5, PHP 7

Function description: The mb_ereg_search_getregs() function returns the matching result array of the most recent multibyte regular expression search.

Usage: The usage of the mb_ereg_search_getregs() function is as follows:

 mb_ereg_search_getregs(): array|false

This function has no parameters.

Return value:

• If a multibyte regular expression is successfully matched, an array containing the matching results is returned.
• If no match is reached, false is returned.

Example:

 $str = "Hello World!"; mb_regex_encoding("UTF-8"); mb_ereg_search_init($str, "l+"); if (mb_ereg_search()) { $regs = mb_ereg_search_getregs(); print_r($regs); }

Output:

 Array ( [0] => ll )

In the example above, we first set the string encoding to UTF-8, then initialize the regular expression search using the mb_ereg_search_init() function, and then search using the mb_ereg_search() function. If a match is found, we use the mb_ereg_search_getregs() function to get the matching result array and print the result using the print_r() function.

Note: Before using the mb_ereg series function, you must call the mb_regex_encoding() function to set the character encoding.
