Compare an array string with a string - php

Question

i am finishing a project, but i need to compare if a HTTP Status Code is the same as another. I have a big algorithm and i reduced them and i identified the problem:
I have an array called "$file_headers", and in the ["Status"] position saves "HTTP/1.1 301 Moved Permanently", and in the if clause i compare to "HTTP/1.1 301 Moved Permanently" (which obviously is the same), but my code doesn't say the same as me. I detect the HTTP Status Code using cURL. My PHP code is the following:
<?php
// create curl resource
$ch = curl_init();
// set url
curl_setopt($ch, CURLOPT_URL, "fb.com");
//return the transfer as a string
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
//enable headers
curl_setopt($ch, CURLOPT_HEADER, 1);
//get only headers
curl_setopt($ch, CURLOPT_NOBODY, 1);
// $output contains the output string
$output = curl_exec($ch);
// close curl resource to free up system resources
curl_close($ch);
$data = explode("\n",$output);
$headers_one = $data;
$headers_two = array();
$headers_two['Status'] = $data[0];
array_shift($data);
foreach($data as $part){
$middle = explode(":",$part);
$msg = null;
if(sizeof($middle) > 2){
if(strpos($middle[0],"Location") === false){
for($i = 1; $i <= sizeof($middle)-1;$i++){
$msg .= $middle[$i];
}
} else {
for($i = 1; $i <= sizeof($middle)-1;$i++){
if($i == 1){
$msg .= $middle[$i] . ":";
} else {
$msg .= $middle[$i];
}
}
}
} else if(isset($middle[1])){
$msg = $middle[1];
}
$headers_two[trim($middle[0])] = trim($msg);
}
array_pop($headers_one);
array_pop($headers_one);
array_pop($headers_two);
$file_headers = $headers_two;
if($file_headers["Status"] === ("HTTP/1.1 301 Moved Permanently") || $file_headers["Status"] === ("HTTP/1.1 301")){
echo "OK!";
} else {
echo "NO!";
}
//print all headers as array
/*echo "<pre>";
print_r($headers_one);
echo "</pre><br />";*/
echo "<pre>";
echo $file_headers["Status"];
echo "</pre>";
?>
If anyone can help me i would appreciate it. THANKS AND HAVE A NICE DAY DEV!

$headers_two['Status'] is the only element you're not trim()ing, so it has some whitespace around it, which makes the comparison fail. Do it like this:
$headers_two['Status'] = trim($data[0]);
And it'll work just fine.
