If this flag is set, parenthesized expression in the delimiter pattern will be captured and returned as well. If this flag is set, only non-empty pieces will be returned by preg_split(). A limit of -1 or 0 means “no limit”.įlags can be any combination of the following flags (combined with the | bitwise operator): If specified, then only substrings up to limit are returned with the rest of the string being placed in the last substring. preg_split (pattern, subject, limit = -1, flags = 0 ) patternĭetermine a string as the pattern to search for. PHP preg_split() function splits string by a regular expression. If you enter a negative number for the limit, the last items of the returned array will be ignored. If you enter the number that is more than the separated elements, elements will be the maximum number of the separated elements $cars = "Ferrari,Benz,BMW,Volvo,Toyota" If you set the limit with a positive number, the function will return the exploded string into an array with the entered number of elements. ![]() $cars = "Ferrari,Benz,BMW,Volvo,Toyota" ġ => string 'Benz,BMW,Volvo,Toyota' (length=21) If you set the limit parameter to zero, the function will return the whole string as an array. $cars = "Ferrari,Benz,BMW,Volvo,Toyota" Ĥ => string 'Toyota' (length=6) PHP explode function with the limit parameter $cars = "Ferrari,Benz,BMW,Volvo,Toyota" Ġ => string 'Ferrari,Benz,BMW,Volvo,Toyota' (length=29) You can set the separator of any separator character. If the limit parameter is zero, then this is treated as 1. If the limit parameter is negative, all components except the last limit are returned. If the limit is positive, the returned array will contain a maximum of limit elements with the last element containing the rest of the string. The “separator” parameter cannot be an empty string. explode(separator, string, limit = PHP_INT_MAX) separator ![]() In this tutorial, we are going to discuss splitting a string into an array with explode() function and PHP loop. PHP explode() is a built-in function that is used to split a string into a string array on boundaries formed by the separator.
