php將字符串隨機分割成不同長度數組的方法

 　　本文實例講述了php將字符串隨機分割成不同長度數組的方法。分享給大家供大家參考。具體分析如下：

　　這裡使用php對字符串在指定的長度范圍內進行隨機分割，把分割後的結果存在數組裡面

　　?

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. ) */
