conversion php5 to php4: Help needed

Hi friends,

Hello, I am French, excuse me for the very bad translation.

Here’s my problem. I’ve a script that works under PHP5, but I think that I could easily adapt it to the PHP4, that’s not very hard to make scripts both PHP4 and PHP5 compatible. Unfortunately, I’m not able to manage it correctly and I can’t convert it.

Can you help me to make this conversion?
Here some explanations (see below):

A part of script:

<?php
class cTypoGenerator
{
	var $keyboard = array(
		'1' => array( '2', 'q' ),
		'2' => array( '1', 'q', 'w', '3' ),
		'3' => array( '2', 'w', 'e', '4' ),
		'4' => array( '3', 'e', 'r', '5' ),
		'5' => array( '4', 'r', 't', '6' ),
		'6' => array( '5', 't', 'y', '7' ),
		'7' => array( '6', 'y', 'u', '8' ),
		'8' => array( '7', 'u', 'i', '9' ),
		'9' => array( '8', 'i', 'o', '0' ),
		'0' => array( '9', 'o', 'p' ),
		'-' => array( '0', 'p' ),

		'q' => array( '1', '2', 'w', 'a' ),
		'w' => array( 'q', 'a', 's', 'e', '3', '2' ),
		'e' => array( 'w', 's', 'd', 'r', '4', '3' ),
		'r' => array( 'e', 'd', 'f', 't', '5', '4' ),
		't' => array( 'r', 'f', 'g', 'y', '6', '5' ),	
		'y' => array( 't', 'g', 'h', 'u', '7', '6' ),
		'u' => array( 'y', 'h', 'j', 'i', '8', '7' ),
		'i' => array( 'u', 'j', 'k', 'o', '9', '8' ),
		'o' => array( 'i', 'k', 'l', 'p', '0', '9' ),
		'p' => array( 'o', 'l', '0' ),

		'a' => array( 'z', 's' , 'w', 'q' ),
		's' => array( 'a', 'z', 'x', 'd', 'e', 'w' ),
		'd' => array( 's', 'x', 'c', 'f', 'r', 'e' ),
		'f' => array( 'd', 'c', 'v', 'g', 't', 'r' ),
		'g' => array( 'f', 'v', 'b', 'h', 'y', 't' ),
		'h' => array( 'g', 'b', 'n', 'j', 'u', 'y' ),
		'j' => array( 'h', 'n', 'm', 'k', 'i', 'u' ),
		'k' => array( 'j', 'm', 'l', 'o', 'i' ),
		'l' => array( 'k', 'p', 'o' ),

		'z' => array( 'x', 's', 'a' ),
		'x' => array( 'z', 'c', 'd', 's' ),
		'c' => array( 'x', 'v', 'f', 'd' ),
		'v' => array( 'c', 'b', 'g', 'f' ),
		'b' => array( 'v', 'n', 'h', 'g' ),
		'n' => array( 'b', 'm', 'j', 'h' ),
		'm' => array( 'n', 'k', 'j' )
	);

	function getWrongKeyTypos( $word )
	{
		$word = strtolower( $word );
		$typos = array();
		$length = strlen( $word );
		echo "<br>Longueur:".$length;

		for( $i = 0; $i < $length; $i++ )
		{

			$talettre = $word{$i};
			echo "<br>(".$talettre.")";
			echo "<br>(".$i.")";
            		if( self::$keyboard($talettre) )
			{

				$tempWord = $word;
				foreach( self::$keyboard($talettre) as $char )
				{
					$tempWord{$i} = $char;			
					array_push( $typos, $tempWord );
				}
			}
		}

		return $typos;
	}
}

echo "le formulaire contient " . $_POST['word'];
$word = $_POST['word'];
$typos = array();
$typos = cTypoGenerator::getWrongKeyTypos( $word );
foreach ($typos as $value){
	$sign1.= "$value,";
}
echo "sign1 ".$sign1;
?> 

Code (markup):

The part which poses problem to me is this one:

if( self::$keyboard($talettre) )

Code (markup):

The current result is as follows: only the first letter of my word is analyzed, then the loop stops. And I can’t determine how to make turn this script in php4. Can you help me to resolve this situation?

While i can't help out with that code particularly, here's a link that gives a list of techniques on how to make your PHP5 code PHP4 compatible.
