PHP：在斯普利特的字符串数组的foreach CHAR [英] PHP: Split a string in to an array foreach char

问题描述

让您的密码至少需要资金，并仔细的一个符号或数字我想提出一个方法。
我想分裂字符串失去字符，然后使用preggmatch来算，如果它包含一个资本和符号/数字。

I am making a method so your password needs at least one captial and one symbol or number. I was thinking of splitting the string in to lose chars and then use preggmatch to count if it contains one capital and symbol/number.

不过，我的确在动作脚本这样的事情，但无法弄清楚这是怎么叫的PHP。我不能找到一种方法，把每个词的一个字符数组中

however i did something like this in action script but can't figure out how this is called in php. i cant find a way to put every char of a word in a array.

AS3例如

    for(var i:uint = 0; i < thisWordCode.length -1 ; i++)
{
	thisWordCodeVerdeeld[i] = thisWordCode.charAt(i);
	//trace (thisWordCodeVerdeeld[i]);
}

谢谢，
Matthy

Thanks, Matthy

推荐答案

您可以访问字符的字符串以同样的方式，你会访问数组的索引，例如

You can access characters in strings in the same way as you would access an array index, e.g.

$length = strlen($string);
$thisWordCodeVerdeeld = array();
for ($i=0; $i<$length; $i++) {
    $thisWordCodeVerdeeld[$i] = $string[$i];
}

你也可以这样做：

You could also do:

$thisWordCodeVerdeeld = str_split($string);

然而，你可能会发现更容易验证字符串作为整个字符串，例如使用常规的前pressions。

However you might find it is easier to validate the string as a whole string, e.g. using regular expressions.
