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:
這里使用php對字符串在指定的長度范圍內進行隨機分割,把分割后的結果存在數組里面
- 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.
- )
- */
希望本文所述對大家的php程序設計有所幫助。
