str_split

Description

Converts a string to an array. If the optional split_length parameter is specified, the returned array will be broken down into chunks with each being split_length in length, otherwise each chunk will be one character in length.

FALSE is returned if split_length is less than 1. If the split_length length exceeds the length of string, the entire string is returned as the first (and only) array element.

Example 1. Example uses of str_split() <?php $str = "Hello Friend"; $arr1 = str_split($str); $arr2 = str_split($str, 3); print_r($arr1); print_r($arr2); ?> Output may look like: Array ( [0] => H [1] => e [2] => l [3] => l [4] => o [5] => [6] => F [7] => r [8] => i [9] => e [10] => n [11] => d ) Array ( [0] => Hel [1] => lo [2] => Fri [3] => end )

Example 2. Examples related to str_split() <?php $str = "Hello Friend"; echo $str{0};  // H echo $str{8};  // i // Creates: array('H','e','l','l','o',' ','F','r','i','e','n','d') $arr1 = preg_split('//', $str, -1, PREG_SPLIT_NO_EMPTY); ?>
