Does File_Get_Contents() Have a Timeout Setting

file_get_contents() Timeout in php

The default value for a timeout in file_get_contents() is 60 seconds.
You can change this value through the default_socket_timeout setting.
It's also doable in your code:

ini_set('default_socket_timeout', 2); // 2 seconds

if file_get_contents timeout, do something else

My Answer:
I saw this topic before
Does file_get_contents() have a timeout setting?
but it wasn't exactly what I want. I wanted to do something else if the timeout happens.
so I used this code:

$ctx = stream_context_create(array(
   'http' => array(
       'timeout' => 5
       )
   )
);
$url = 'source URL';
$content = file_get_contents("$url", 0, $ctx);
if(!$content){
   echo 'timeout happened';

}elseif (another condition) {
   echo 'condition result'

}else {
   echo 'something else'
}

PHP - Setting a file_get_contents timeout

Add a timeout key inside the stream_context_array

$Context = stream_context_create(array(
'http' => array(
    'method' => 'GET',
    'timeout' => 30, //<---- Here (That is in seconds)
)
));

Your Question....

will file_get_headers return FALSE if it has not completed yet and
will PHP move to the next line if it has not completed the
file_get_contents request?

Yes , it will return FALSE along with the below warning message as shown.

A connection attempt failed because the connected party did not
properly respond after a period of time, or established connection
failed because connected host has failed to respond.

How to set time limit for file_get_contents()?

You can use the HTTP context option

So the code would look like

$options = stream_context_create(array('http'=>
    array(
    'timeout' => 10 //10 seconds
    )
));
echo file_get_contents('http://example.com/', false, $options);

php file_get_contents when does connection close?

file_get_contents uses a regular stream context that you can even pass as 3rd parameter. You can either set a timeout option there.

$ctx = stream_context_create([
    'http' ['timeout' => 10]
]);

$content = file_get_contents('http://...', FALSE, $ctx);

When you do not specify a http.timeout context setting, it will default to the default_socket_timeout php.ini setting (which is set to 60 seconds on most systems by default).

Timeout for file_get_contents don't works in PHP

for stream_context_create() http://php.net/manual/en/function.stream-context-create.php it needs [ array $options [, array $params ]]
when you pass your $header it doesnt appear that your building the array correctly. would something like this work?

public function myPost($content, $timeout = null)
{
    $timeInit = new DateTime();

    $this->method = 'POST';


    $header = array();
    $header['header'] = null;
    $header['content'] = is_array($content) ? http_build_query($content) : $content;
    $header['method'] = $this->method;

    if ($timeout) {
        $header['header']['timeout'] = $timeout;
    }

    $header['header']['Content-length'] . strlen($header['content']);
    $headerContext = stream_context_create(array('http' => $header));
    $contents = file_get_contents($this->url, false, $headerContext);
    $this->responseHeader = $http_response_header;

    $timeFinal = new DateTime();
    $this->time = $timeInit->diff($timeFinal);

    return $contents;
}

but a better way would be to use it like the example says, e.g.

$timeInit = new DateTime();

// all your defaults go here
$opts = array(
    'http'=>array(
        'method'=>"POST",
    )
);

//this way, inside conditions if you want
$opts['http']['header']  = "Accept-language: en\r\n" .  "Cookie: foo=bar\r\n";
$context = stream_context_create($opts);
