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　　? 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 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。
