[SOLVED] Check for a key?

[DeanWhitehouse]

Is it possible to check an array for a certain key rather than just the value.

 

E.g.

$array = array("test",50 => "tester");

if(in_array_key(50,$array))

echo "In array key";

 

That will return true because the key is named 50.

 

Any ideas?

Not sure where to post this, but it might come in handy for some people.

 

If you use a custom 404 page, etc.

 

Then here is an array containing the error message and error description.

 

<?php
if(isset($_GET['error']))
{
$error = $_GET['error'];
$error_ids = array(
400 => "Bad Request",
401 => "Authorization Required",
402 => "Unknown Error",
403 => "Forbidden",
404 => "Not Found",
405 => "Method Not Allowed",
406 => "Not Acceptable",
407 => "Proxy Authentication Required",
408 => "Request Timed Out",
409 => "Conflicting Request",
410 => "Gone",
411 => "Content Length Required",
412 => "Precondition Failed",
413 => "Request Entity Too Long",
414 => "Request URI Too Long",
415 => "Unsupported Media Type",
500 => "Internal Server Error",
501 => "Unknown Error",
502 => "Bad Gateway",
503 => "Service Unavailable",
504 => "Gateway Timeout",
505 => "HTTP Version Not Supported"
);
$error_det = array(
400 => "a syntax error in the request.",
401 => "you not having permission to access this data.",
402 => "unknown reasons.",
403 => "you not having permission to access this data or the server being unable to server the requested data.",

);
if(array_key_exists($type,$error_ids))
       echo $error_ids[$error]." - ".$error_det[$error];
}
?>
