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. ) */ |
