Problem with encryption script

[Drezard]

Okay I'm trying to write a PHP Script to that splits a string up then uses a switch statement to change the characters into numbers. So far thats all I got. But, it doesn't work for some reason. It works and doesn't display any errors but it doesn't give the output I wanted.

 

Heres the script:

<?php

if (!isset($_POST['submit'])) {

echo "* are required fields <br /> <br />

	  Form: <br /> <br />
	  <form method='POST'>

	  *String <input type='text' name='string'> <br />
	  
	  <input type='submit' name='submit'>
	  </form> <br />";

}

if (isset($_POST['submit'])) {

$string = mysql_escape_string($_POST['string']);

$arr = str_split($string);

$arrsize = count($arr);

for ($int = 0; $int > $arrsize; $int++) {

	switch ($arr[$int]) {
		case 'a':
    			$char = 1;
    		break;
		case 'b':
    			$char = 2;
    		break;
		case 'c':
    			$char = 3;
    		break;	
		case 'd':
    			$char = 4;
   			break;
		case 'e':
		   	$char = 5;
    		break;
		case 'f':
    			$char = 6;
    		break;	
		case 'g':
    			$char = 7;
    		break;
		case 'h':
    			$char = 8;
    		break;
		case 'i':
    			$char = 9;
    		break;
		case 'j':
    			$char = 10;
    		break;
		case 'k':
    			$char = 11;
    		break;	
		case 'l':
    			$char = 12;
    		break;
		case 'm':
    			$char = 13;
    		break;
		case 'n':
    			$char = 14;
    		break;
		case 'o':
    			$char = 15;
    		break;	
		case 'p':
    			$char = 16;
    		break;
		case 'q':
    			$char = 17;
    		break;
		case 'r':
    			$char = 18;
    		break;	
		case 's':
    			$char = 19;
    		break;
		case 't':
    			$char = 20;
    		break;
		case 'u':
    			$char = 21;
    		break;
		case 'v':
    			$char = 22;
    		break;
		case 'w':
    			$char = 23;
    		break;	
		case 'x':
    			$char = 24;
    		break;
		case 'y':
    			$char = 25;
    		break;
		case 'z':
    			$char = 26;
    		break;	
		case ' ';
			$char = 27;
		break;

		echo $char . "<br>";			

	}

}

}

?>

 

It should do something like this:

Input: drezard

 

Output:

d

r

e

z

a

r

d

 

 

Whats wrong with this script?

I have jst tried running it and I get a

Fatal error: Call to undefined function: str_split() in C:\Program Files\xampp\htdocs\phptest\string.php on line 21

 

according to the manual it only runs in PHP5 which I dont have so I had to geta function to help me, your problem is that the

echo $char . "<br>";	

 

is one curly brace too high it should be

 

case 'y':
    			$char = 25;
    		break;
		case 'z':
    			$char = 26;
    		break;	
		case ' ';
			$char = 27;
		break;



	}
	echo $char . "<br>";	
}

 

hello comes out as
