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.
)
