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
strlen($str)) ? strlen($str) : $p;
$buffer = substr($str,$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。
