Define a time limit in PHP with cURL

In this guide, we'll show you how you can set a conversion time limit at PDFShift. This will allow you to define a maximum time for the conversion process to complete, and if the process takes longer than the defined time, the conversion will be aborted.

In some cases, this can be useful if you want the request to not be too long and then handle failure on your end depending on the result.

To do so, we use the timeout property, which is the maximum time in seconds that the request is allowed to take. If the request takes longer than the defined time, the conversion will be aborted.

# You can get an API key at https://pdfshift.io
$api_key = 'sk_xxxxxxxxxxxx'

$params = array (
    'source' => 'https://www.example.com',
    'timeout' => 10
)

$curl = curl_init('https://api.pdfshift.io/v3/convert/pdf');
curl_setopt($curl, CURLOPT_RETURNTRANSFER, true);
curl_setopt($curl, CURLOPT_POST, true);
curl_setopt($curl, CURLOPT_POSTFIELDS, json_encode($params));
curl_setopt($curl, CURLOPT_HTTPHEADER, array(
    'Content-Type: application/json',
    'Authorization: Basic ' . base64_encode('api:' . $api_key)
));

$response = curl_exec($curl);
if ($response === false) {
    $error_message = curl_error($curl);
    curl_close($curl);
    throw new Exception("cURL error: $error_message");
}

// Get the HTTP status code
$http_status = curl_getinfo($curl, CURLINFO_HTTP_CODE);

// Close cURL resource
curl_close($curl);

// Check if the request was successful
if ($http_status !== 200) {
    throw new Exception("Request failed with HTTP status code: $http_status");
}

// Save the file to result.pdf
file_put_contents('result.pdf', $response);

echo 'The PDF document was generated and saved to result.pdf';

In the above example, the conversion could fail if the conversion takes longer than 10 seconds.

For further details on the timeout property and its usage, please refer to our dedicated documentation.
