php将字符串随机分割成不同长度数组的方法，php字符串长度数组本文实例讲述了php将字符串随机分割成不同长度数组的方法。分享给大家供大家参考。具体分析如下：
这里使用php对字符串在指定的长度范围内进行随机分割，把分割后的结果存在数组里面
function randomsplit($min, $max, $str){ $a = array(); while ($str != ''){ $p = rand($min, $max); $p = ($p > strlen($str)) ? strlen($str) : $p; $buffer = substr($str, 0, $p); $str = substr($str, $p, strlen($str)-$p); $a[] = $buffer; } return $a;}//范例：/*** example:*/$test_string = 'this is a example to test the randomsplit function.';print_r(randomsplit(1, 7, $test_string));/*outputs something like this(array items are 1 to 7 characters long): array( [0] => this [1] => is [2] => a exam [3] => ple to [4] => test t [5] => he [6] => [7] => ran [8] => d_spl [9] => it f [10] => un [11] => ction.)*/
希望本文所述对大家的php程序设计有所帮助。
