Form Value To A Array

Randomizer

Well anywho the title says most of it but here's what I want to do: I need to convert a form value to a array letter by letter (or character so to speak). So I have:

Form Value

and I want to break that up into a array with the values 'F', 'o', 'r', 'm', ' ', 'V', 'a', 'l', 'u', 'e' | is there anyway to do this?

Many Thanks

You don't need to:
A string value is an array by itself.
So:

$string = "SomeStrangeString";
$string[0] == "S";
$string[4] == "e";

leatherback: that's interesting. I never knew that. But $string isn't actually an array.

You can access what would be array keys by doing $string[0] and $string[1] and so forth, but if you try to put $string in a foreach loop, it doesn't accept it as a valid argument for an array.

$string = "SomeStrangeString"; 

foreach($string as $key => $value) {
   echo "Key is: " . $key . ". Value is: " . $value . "<br>";
}

The above produces the following error:

Warning: Invalid argument supplied for foreach() in /home/webs/your_server/http/html/theFile.php on line 5

So a string isn't actually an array, but you can access each letter individually by adding numeric indices to the variable.

Thank You very much that's exactly what I wanted ^_

It's relatively trivial to change a string into an array:

$count=(strlen($string));

$myarray=array();

while ($x<$count) {
   $myarray[$x]=$string[$x];
   $x++;
   }

---the question I have is, why couldn't I find a native function that does this?

One possible answer is that I haven't yet spent the whole morning in the manual...but with search tools like they have, I shouldn't have to spend the whole morning...

Well, OK THEN! http://www.php.net/manual/en/function.str-split.php

Funny thing is I already found that function but it was for php 5 and CVS and i didn't know what the hay that ment so I went searching for another solution, also while trying to make my own little script i couln't seem to find a function that measured the strings length and then here it pops up ^_

Good point ... I should have read the fine print :eek:
