php array. unable to find value from the key

Question

please help me figure out the error to find the value by key. As the value is printed when using a string but not a variable with the same value. Thanks in advance

Code:

print_r($ESSID_data);
print_r($ESSID_data['criticalboot']);
print_r($myssid);
print_r($ESSID_data[$myssid]);

output:

Array ( [criticalboot] => Array ( [0] => CCMP [1] => PSK ) ) 
Array ( [0] => CCMP [1] => PSK ) 
criticalboot 
Undefined index: criticalboot

I tested this by declaring $ESSID_data = array("criticalboot" => array("CCMP", "PSK")); and $myssid = "criticalboot"; and it works just fine. — Stefan

Try to do trim() first before feeding it into the index. Like:

$myssid = trim($myssid);
print_r($ESSID_data[$myssid]);
