Find if value exists in a JSONArray in php

Question

I have a JSONArray as shown below

{
    "output": [
        "a",
        "b",
        "c",
        "d",
        "e"
    ]
}

I need to find if "e" exists in the above array in php. Can someone help me out with this ?

what's with the downvotes? this is a perfectly fine question from a beginner — Jonah

I'm guessing it's because the asker has shown none of their own efforts in trying to solve the issue, it comes across a little like: Hey do this for me cheers bye. — Dale

well I need to know what to search inorder to find my answer. I managed to do it the C++ way of traversing through each element and finding out the value and comparing it. Just thought this would help me understand some functions in php. — Lalith B

@lalith Tip: Always do a simple search in the manual: php.net/manual-lookup.php?pattern=find+in+array, 90% of the time that answers your question. — deceze

$array = json_decode($json, true);
if (in_array('e', $array['output'])) {
    ...
}
