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。
