The mb_ereg_search_regs() function is an inbuilt function in PHP that is used for regular expressions to match a given string. If the match is found, then it will return the matched part as an array.
Syntax:
mb_ereg_search_regs(
?string $pattern = null,
?string $options = null
): array|false
Parameters: This function accepts two parameters that are described below.
- $pattern: This is the regular expression parameter that is used to search a pattern in the given string.
- $options: This parameter is optional. That is used to specify matching options. It can be ‘m’ for multiline, the ‘^’ and ‘$’ anchors will match the beginning and end of each line in the input string.
Return Values: The mb_ereg_search_regs() function returns an array that contains the matched part of the multibyte regular expression. If the function successfully executes, it returns “true”, otherwise this function returns “false”.
