unable to sort array

[jason310771]

For some reason I can not sort the array list, can anyone tell me what I am doing wrong ?

 

My output is...

 

Array ( [0] => 2 [1] => 5 [2] => 3 )


1

$product_length = 2;
$product_width = 5;
$product_height = 3;

            // work out volume.
            $sizeArray = array();
            $sizeArraySORTED = array();
            $sizeArray = array($product_length, $product_width, $product_height);
print_r($sizeArray); ?><br><br><br><?
            $sizeArraySORTED = asort($sizeArray, SORT_NUMERIC);
print_r($sizeArraySORTED);

asort() does not return an array. It sorts the array in the parameter.

and it returns a boolean so 

print_r($sizeArraySORTED);

cannot give you the output that you are claiming to get...

There are two print_r() statements which are generating the output.

 

 

<?php
print_r($sizeArray);  //<-- shows an array
print_r($sizeArraySORTED);  //<-- shows "1"
?>

I did see those, I didn't see the '1' danling at the bottom of the text :-)

 

But that raises the question why the OP didn't look at asort() to see how it works...

Just in case you didn't follow Barand's response. The array asort function will sort the original variable - no need to assign the result to a variable. A couple other things. No need to define $sizeArray as an empty array and then define it again as an array with values. You only need to define an empty array first if you need to use the variable as an array in some way. For example, if you add values to the array using $sizeArray[] = 'foo';

 

 

$product_length = 2;
$product_width = 5;
$product_height = 3;

// work out volume.
$sizeArray = array($product_length, $product_width, $product_height);
echo "Presort:<br><pre>" . print_r($sizeArray, 1) . "</pre>";
echo "<br><br><br>\n";
asort($sizeArray, SORT_NUMERIC);
echo "Sorted:<br><pre>" . print_r($sizeArray, 1) . "</pre>";
