Building multidimensional array from url params

[dangermark]

Hi all,

 

I am trying to build a multidimensional array from values in a URL.

 

For example:

 

page.php?ind=123&loc=456&wt=789 needs to build the array like this:

Array 
( 
[0] => Array 
     ( 
     [0] => 123
     ) 
[1] => Array 
     ( 
     [0] => 456
     ) 
[2] => Array 
     ( 
     [0] => 789
     ) 
)

 

If one of these params is empty: page.php?ind=123&loc=&wt=789

 

I need the array to be

 

Array 
( 
[0] => Array 
     ( 
     [0] => 123
     ) 
[1] => Array 
     ( 
     [0] => 789
     ) 
) 

 

I am having some trouble wrapping my head around how to do this. I am using array_push to construct it, but i fear I may be missing something. There's a good change I am way off too .  Any suggestions would be greatly appreciated.

 

My code:

 

<?php 

// get the id from the URL
if (isset($_GET['ind'])) {
$indId = $_GET['ind'];
}
if (isset($_GET['loc'])) {
$locId = $_GET['loc'];
}
if (isset($_GET['wt'])) {
$wtId = $_GET['wt'];
}

$searchArray = array();

if (!isset($_GET['ind'])) {
empty($_GET['ind');
} else {
array_push($searchArray, $ind);
}

if (!isset($_GET['loc'])) {
empty($_GET['loc']);
} else {
array_push($searchArray, $loc);
}

if (isset($_GET['wt'])) {
empty($_GET['wt']);
} else {
array_push($searchArray, $wt);
}

echo '<pre>';
print_r($searchArray);
echo '</pre>';

?>

Here is how I would do it:

 

<?php 

$searchArray = array();

if (!empty($_GET['ind'])) {
array_push($searchArray, $_GET['ind']);
}

if (!empty($_GET['loc'])) {
array_push($searchArray, $_GET['loc']);
}

if (!empty($_GET['wt'])) {
array_push($searchArray, $_GET['wt']);
}

echo '<pre>';
print_r($searchArray);
echo '</pre>';

?>

 

The reason for using "not empty" instead of "isset" is that an empty variable is set, and you don't want an empty variable included in the array.

That was exactly my problem; the array still being entered but empty.

 

Thanks a bunch for that, modified it slightly though to suit my 2 dimensional array:

 

if (!empty($_GET['ind'])) {
array_push($searchArray, array($_GET['ind']));
}

 

Thanks a lot! Works perfectly.
