PHP:将字符串拆分为数组 foreach char

问题描述

我正在制定一种方法，因此您的密码至少需要一个大写字母和一个符号或数字.我正在考虑将字符串拆分为丢失字符，然后使用 preggmatch 来计算它是否包含一个大写字母和符号/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.

但是我在动作脚本中做了类似的事情，但无法弄清楚这是如何在 php 中调用的.我找不到将单词的每个字符放入数组中的方法.

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 示例

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

谢谢，马蒂

推荐答案

您可以像访问数组索引一样访问字符串中的字符，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:

$thisWordCodeVerdeeld = str_split($string);

但是您可能会发现将字符串作为一个完整的字符串进行验证更容易，例如使用正则表达式.

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