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。
