[RESOLVED] array output probs

[steamPunk]

Hi

I've written a function that will echo all the arrays in session variables in a page with the key name and the value

this is what it looks like

	foreach ($_SESSION as $key => $value) {
		$arry = $value;
		if(is_array($arry)){
			$html .= "<strong>$key</strong><br />\n";
			foreach ($arry as $key => $value) {
				$html .= "----$key = $value<br />\n";
			}
		}else{
			$html .= "<strong>$key</strong> = $value<br />\n";	
		}
	}

this works fine for arrays where the key has a name, eg this :

$_SESSION['commande']["date"]

echoes this:

----date = 2007-11-26

but it doesn't work if the key is just a generated number ($c), eg this :

$_SESSION['panArray'][$c]=array("pan_id"=>$row['pan_id'],
							"slot_id"=>$row['slot_id'],
							"pan_groupe"=>$row['pan_groupe'],
							"admin_id"=>$row['admin_id'],
							"pan_texte"=>stripslashes($row['pan_texte']),
							"pan_prix"=>$row['pan_prix']);

echoes this :

----1 = Array
----2 = Array
----3 = Array
----4 = Array

what would i need to do for all the types of array to output the same ?

thanks

ARG ! I've just realized why it was doing that - because some of the session vars have 3 levels instead of just 2 - i can't believe i hadn't thought of that

so i added in a third level and now it looks like this

function echoSessions(){
	$html = "";
	$html .= "<div id=\"sessionsLink\" onclick=\"toggleTarget('sessions','block');\" style=\"padding:6px;border:#999999 1px solid; background-color:#EBEBEB;width:200px;\">See the sessions</div>
			<div id=\"sessions\" onclick=\"toggleTarget('sessions','none');\" style=\"display:none;\">";
	foreach ($_SESSION as $key => $value) {	
		$arry = $value;
		if(is_array($arry)){
			$html .= "<strong>$key</strong><br />\n";
			foreach ($arry as $key2 => $value2) {			
				if(is_array($value2)){
					$html .= "-------\n";
					//$html .= "----$key2 = $value2<br />\n";
					foreach ($value2 as $key3 => $value3) {				
						$html .= " $key3 = $value3 ,";
					}
					$html .= "<br />\n";
				}else{				
					$html .= "----$key2 = $value2<br />\n";
				}
			}
		}else{
			$html .= "<strong>$key</strong> = $value<br />\n";	
		}	
	}
	$html .= "</div>";
	return $html;
}

what i need now is a way of diong that recursively instead of hard-coding in all the levels - but that's another story

thanks to all those who may have looked at this problem

I finally managed to make it recursive - so now i have a drop-in SESSIONS monitor that i am very pleased with and would like to share with you

Put the main function call in your header include so it will appear in all pages - you'll see a grey rectangle containing the phrase "see the sessions" - when you click on it the sessions div will become visible - if you click on the sessions div it will disappear

the functions are here :

function addSpaces($level){
	$spaces = "";
	for($i=1;$i<=($level*3);$i++){
		$spaces .= "&nbsp;";
	}
	return $spaces;
}

function echoSessionsInner($arry,$level){
	$level += 1;
	foreach ($arry as $key => $value) {						
		if(is_array($value)){
			$html .= addSpaces($level)."<strong>".$key."</strong><br />\n";		
			$html .= echoSessionsInner($value,$level);			
			$html .= "<br />\n";
		}else{				
			$html .= addSpaces($level).$key." = ".$value."<br />\n";
		}						
	}
	return $html;
}

function echoSessions(){
	$html = "";
	$html .= "<div id=\"sessionsLink\" onclick=\"toggleTarget('sessions','block');\" style=\"padding:1px;border:#999999 1px solid; background-color:#EBEBEB;width:100px;\">See the sessions</div>
	<div id=\"sessions\" onclick=\"toggleTarget('sessions','none');\" style=\"display:none;\">";				
	$html .= echoSessionsInner($_SESSION,0);	
	$html .= "</div>";
	return $html;
}

you put this in your header include (you can comment it out to stop it showing)

<?php echo echoSessions(); ?>

and here's the javascript for toggling the div display :

//  onclick="toggleTarget('div_id','block_or_none')"
function toggleTarget(what,how){	
	if(document.getElementById){
		document.getElementById(what).style.display=how;
	}
}

hope this is of some use to someone - i haven't tested it anywhere apart from in FF2 on WinXP but it should work in most situations
