Question

How can I do a comparison when my array returns value with index.
Returned value is Array ( [isMember] => 0 ) and I want do to a comparison on the value only
if ($memberStatus == 0)
{
print_r($memberStatus);
}

Answer 1

Explanation
Index Array's value can be access by using corresponding index value where as an Associative Array's value can be access by using corresponding key along with array name and in between square brackets that is
arrayName["index-value"]
or
arrayName["key-name"].
You may refer to the following code.
Code
//For Associative Array
$arrayOne = array(
'keyone' => 'a',
'keytwo' => 'b',
'keythird' => 'c'
);
if ($arrayOne['keyone'] == 'a') {
print_r($arrayOne['keyone']);
//output a
}
OR
//For Index Array
$arrayOne = array('a', 'b', 'c');
if ($arrayOne[0] == 'a') {
print_r($arrayOne[0]);
//output a
}

Answer 2

If you have an array like this:
$data = [ 'isMember' => 0, 'data1' => 1, 'data2' => 2 /* ... */ ];
You can access single elements by using the name of the array and write the key in square brackets:
// change isMember to whatever key-value pair you need
$memberStatus = $data['isMember'];
if ($memberStatus === 0)
{
print 'user is a member';
}
else
{
print 'user it not a member';
}

Answer 3

I think what you are looking for is:
$myArray = array(
'isMember' => 0
);
if ( $myArray['isMember'] == 0 ) {
print_r($myArray['isMember']);
}

Answer 4

Are you looking for a key inside an array? Then you need:
echo array_key_exists(9, [1=>'nope',2=>'nope',3=>'nope',9=>'yah']) ? 'Yes it does' : 'it doesn\'t';
Otherwise you are looking for:
echo in_array("my value", ["my value", "a wrong value", "another wrong one"]) ? 'yush' : 'naaaaah';
Either way you can use both in a if statement rather than a thernary operator.

Answer 5

I am not sure which type of array you need to compare because there are generally 2 different types of them:
Indexed
- You pick numerical index which do you want to compare
$array = array("admin", "moderator", "user");
if ($array[0] == "user") {
// CODE
}
Associative
- You pick the string key which do you want to compare
$array = array( "id1" => "member", "id2" => "not member","id3" => "user");
if ($array["id2"] == "not member") {
// CODE
}
