[Resolved] Find the content of a VAR using a string with the var name

[simobk]

Second question in just a few minutes interval. As I said in my other post, I am learning, so I have a few questions 🙂

I want to create a function that will handle all the error messages generated by the site.

What I can't find a way to do is that, when I call the function, I want to call it like this : fnMessage('m001'). How can I do so when I call the function like this, it will read the content of the variable named $m001 ?

Here is the code of the function

function fnMessage($noMsg)
{
	$m001 = "succes1";
	$m002 = "succes12";

$m501 = "erreur1";
$m502 = "erreur2";

$no = substr($noMsg,1,3);

if ($no>=500)
{
	$beginMsg = "<br><h3><img src=\"../art/msgSuccess.gif\" align=\"absbottom\">&nbsp;&nbsp;&nbsp;";
	$endMsg = "</h3>";
}
else
{
	$beginMsg = "<br><h3 class=\"Err\"><img src=\"../art/msgErr.gif\" align=\"absbottom\">&nbsp;&nbsp;&nbsp;";
	$endMsg = "</h3>";
}

echo $beginMsg . 'WHAT_GOES_HERE_?' . $endMsg;
}

Any idea on how this could be done? I know it would be easier to just put in a db table, but I don't want to do it like that as I want it to be a reusable module for different projects.

Thanks,

Simo

Hi simo,

You could use an associative array (also called a hash) of messages ...

<?php 
function fnMessage($noMsg) 
{ 
	$msg = array(
	   	"m001" => "succes1"
	,	"m002" => "succes12"
	,	"m501" => "erreur1"
    ,	"m502" => "erreur2"
	); 

$no = substr($noMsg,1,3); 

if ($no >= 500) 
{ 
    $beginMsg = "<br><h3><img src=\"../art/msgSuccess.gif\" align=\"absbottom\">&nbsp;&nbsp;&nbsp;"; 
    $endMsg = "</h3>"; 
} 
else 
{ 
    $beginMsg = "<br><h3 class=\"Err\"><img src=\"../art/msgErr.gif\" align=\"absbottom\">&nbsp;&nbsp;&nbsp;"; 
    $endMsg = "</h3>"; 
} 

echo $beginMsg . $msg[$noMsg] . $endMsg; 
}
?>
