Remove Array Duplicates Without Merging

[matthewtbaker]

Hi,

 

Please could you point me in the right direction...

 

 

I want to compare the two arrays (below) and then remove any duplicate values from my temporary array $arrTemp. In this instance the word 'array' will be removed from $arrTemp as it exists in $arrMain.

 

$arrMain = ('the' , 'main' , 'array');

$arrTemp = ('some' , 'array' , 'stuff');

 

 

I have found solutions which merge the two but this doesn't suit what I need.

 

array_unique(array_merge($arrMain, $arrTemp));

 

 

If you could please provide a solution that would be great. I'd like to avoid loops if possible.

 

Matt

See array_diff.

 

$arrTemp = array_diff($arrTemp, $arrMain)

 

In this case, the array_diff() function returns an array containing all the entries from $arrTemp that are not present in $arrMain.

Try,

$arrMain = array('the' , 'main' , 'array');
$arrTemp = array('some' , 'array' , 'stuff');
$resTemp = array_diff($arrTemp, $arrMain);
echo '<pre>'.print_r($resTemp, true).'</pre>';
