Php foreach character in string

Question

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.

How can I access all characters in a string in PHP?

What is foreach in PHP?

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 example

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

Thanks, Matthy

you can convert a string to array with str_split and use foreach

$chars = str_split($str);
foreach($chars as $char){
    // your code
}

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];
}

You could also do:

$thisWordCodeVerdeeld = str_split($string);

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

Since str_split() function is not multibyte safe, an easy solution to split UTF-8 encoded string is to use preg_split() with u (PCRE_UTF8) modifier.

preg_split( '//u', $str, null, PREG_SPLIT_NO_EMPTY )

You can access a string using [], as you do for arrays:

$stringLength = strlen($str);
for ($i = 0; $i < $stringLength; $i++)
    $char = $str[$i];

Try this, It works beter for UTF8 characters (Kurdish, Persian and Arabic):

";}
?>

This is a simple guide on how to loop through the characters of a string in PHP.

First of all, you need to know about the function str_split.

Basically, this function converts a given string into an array. In other words, the string is “split up” and each character is then added as an element to an array.

Note that this will also include special characters and whitespaces.

A short example.

If you run the code above, you’ll see that the $myArray variable is an array that contains each character from our string.

Then, you just loop through it like so.

";
}

The code above will loop through the characters and print them out on separate lines.

As I said, it’s actually pretty simple!
