[Resolved] Displaying arrays

[g7ibby]

I am trying to figure out how to format and display information in an array.

My arrays are set up as follows.

$foo = array(
             array("key1"=>"value1",
                   "key2"=>"value2"),
             array("key1"=>"value3",
                   "key2"=>"value4")
                    );
$bar = array(
             array("key1"=>"value1",
                       "key2"=>"value2");
                    );

$_SESSION['foo'] = $foo;
$_SESSION['bar'] = $bar;

How would I create a loop that will display the data in a table from only the foo array and for each array within foo array within the session?
ie

 
while (somthing loops)
do {
printf ("<tr><td>key1</td><td>key2</td></tr>");
}

Well something along that line anyway.
Am I making sense?

Thanks

i don't think i can work with ur current array code...
if that is really ur array, then is will generate parse error when execute...🙁
please correct the array or set it up correctly.

if it is only for you for e.g. tracking purposes, perhaps this would be enough for you:

echo "<pre>".print_r($your_array)."</pre>";

otherwise, try a recursive method like

/** 
 * show_arr shows an array recursively
 * $i counts the number of recursive calls
 * $arr is the array to be shown.
*/

function show_array($arr, $i=0) {
	if(!is_array($arr))	return $arr;	// nothing to do, $arr is not an array;
	$nl = "\n"; // make some beautiful newlines
	for($y=0;$y<=$i;$y++) {
		$nl .= "\t"; // beautiful tabstops to be able to read the html source
	}
	$foo = $nl."<!-- show array start $i -->".$nl."<table border=0 cellpadding=3 cellspacing=0>";

foreach($arr as $key => $val){

	if(!is_array($val)){
		$foo .= $nl."<tr><td valign=top><b>".$key."</b></td><td valign=top>".$val."</td></tr>";
	} else {
		$i++;
		$foo .= $nl."<tr><td valign=top><b>".$key."</b></td>";
		$foo .= "<td valign=top>";
		$foo .= show_array($val,$i); // walk innervalue recursively
		$foo .= "</td></tr>";
	}
}
$foo .= $nl."</table>".$nl."<!-- show array end $i -->".$nl;
return $foo;
}
#------------------- show_array end;


// output:
echo show_array($your_array);

Sorry jimson
It was more of a example than working code.
It has been corrected in the original post.

axo
The code is for public display. I will start on trying your code example tonight.

Thank you for the assistance.

Thanks axo
It works great.
And your comments are excelent as well.

What could I add to it to make it work from a array added to a session?

[g7ibby]

Never mind it seems to work with sessons already.

Thanks again
