Probably quite a simple question

I am trying to pass an array into a function like in the example below:

//DEFINE FUNCTION
function my_func($ArrayName="")
{//OPEN
print each value from $ArrayName etc...
}//CLOSE

//DEFINE ARRAY
$MyArray=array(
"1"=>"First Element",
"2"=>"Second Element")

//RUN FUNCTION
my_func($MyArray);

OK, the problem I am having is that when the function is run, $ArrayName is not an array!, as far as I can tell this is because $ArrayName itself is a variable containing '$MyArray'...

Any help on how I can pass in the array and its elements would be VERY MUCH appreciated as I dont have much hair left to pull out!

try changing the function to

function my_func($ArrayName)
{//OPEN
print each value from $ArrayName etc...
}//CLOSE

hey thanks for the quick suggestion, I tried and it didnt seem to work..., here is the main file I have, the 'config.php' file is where the array $AppTables is setup and I have tested that that is ok using the code below before I converted it into a function... I am sorry if this file is to big to post here..

<?php
$ConfigFile = "config.php";

function config_summary($ArrayName)
{//FUNCTION START

global $ConfigFile;
global $errorMsg;
echo '$ArrayName= ' . $ArrayName;

if(include($ConfigFile))
{//LOOP 1
	if(is_array($ArrayName))
	{//LOOP 2
		$result	=	TRUE;

		echo '<CENTER><TABLE BORDER=0 CELLPADDING=3 CELLSPACING=1 WIDTH=600 BGCOLOR="#000000" ALIGN="CENTER">';
		echo '<TR BGCOLOR="#9999CC">'; 
		echo "\n<TD><h1><u><b>Array: " . $ArrayName . "</b></u></h1><br><br></TD>\n";
		echo '</TR>';
		echo '</TABLE></CENTER>';

		echo '<CENTER><TABLE BORDER=0 CELLPADDING=3 CELLSPACING=1 WIDTH=600 BGCOLOR="#000000" ALIGN="CENTER">';

		for($n = 0; $n < count($ArrayName); $n++)
			{
			$line = each($ArrayName);
			echo('<TR><TD BGCOLOR="#CCCCFF">' . $line[key] . ' = ' . '</TD><TD BGCOLOR="#CCCCCC">' . $line[value]) . "</TD>\n";
			}

		echo '</TABLE></CENTER><BR>';

	}//END LOOP 2
	else
	{$result	=	FALSE; $errorMsg[]="Argument $ArrayName is not an array";}

}//END LOOP 1
else
{$result	=	FALSE; $errorMsg[]="Error including config file";}

return $result;
}//FUNCTION END

config_summary($AppTables);

?>

hey its knocked me for six 🙂, I shall continue into the night until I find out why, thanks, Andy..

ok, sorted it, basically the problem was that the array passed into the function was created in config.php and that config.php was included inside the function instead of before the function was defined -- doh!

Nice one.
