Question

I have the below array..

<?php $arrLayout = array(
    "section1" => array(
        "wComingEpisodes" => array(
            "title" => "Coming Episodes",
            "display" => ""
        )
    )); 
?>

Then I want to check if wComingEpisodes is in the array so..

<?php if (in_array( "wComingEpisodes" , $arrLayout )) {
echo "CHECKED";}
?>

However its returning nothing even though it is in the array. Do I need to do something different because of the multiple arrays or where is my mistake?

Answer 1

in_array tests for values, not keys. It also does not test nested values.

$arrLayout = array(
"section1" => array(
    "wComingEpisodes" => array(
        "title" => "Coming Episodes",
        "display" => ""
    )
)); 

echo array_key_exists( 
   "wComingEpisodes",
   // this is the array you're actually looking for
   $arrLayout['section1'] )?'exists':'does not exist';
