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。
