Configuração de tempo de espera de solicitação de endereço remoto da solicitação php, explicando principalmente os métodos de configuração de tempo de espera dos três funções simples e comuns file_get_contents, fopen, curl. Geralmente, é recomendado usar curl, que é o melhor em desempenho e eficiência.
1Configuração de tempo de espera de solicitação file_get_contents
$timeout = array( 'http' => array( 'timeout' =>5//Definir um tempo de espera, unidade em segundos ) ); $ctx = stream_context_create($timeout); $text = file_get_contents("https://pt.oldtoolbag.com/",0, $ctx);
2Configuração de tempo de espera de solicitação fopen
$timeout = array( 'http' => array( 'timeout' => 5 //Definir um tempo de espera, unidade em segundos ) ); $ctx = stream_context_create($timeout); if ($fp = fopen("https://pt.oldtoolbag.com/", "r", false, $ctx)) { while( $c = fread($fp, 8192)) { echo $c; } fclose($fp); }
3,curl timeout request setting
CURL is a commonly used lib library for accessing HTTP protocol interfaces, with high performance and some concurrency support features, etc.
curl_setopt($ch, opt) can set some timeout settings, mainly including:
a、CURLOPT_TIMEOUT sets the maximum number of seconds that cURL is allowed to execute.
b、CURLOPT_TIMEOUT_MS sets the maximum number of milliseconds that cURL is allowed to execute.
c、CURLOPT_CONNECTTIMEOUT is the time to wait before initiating the connection. If set to 0, it will wait indefinitely.
d、CURLOPT_CONNECTTIMEOUT_MS is the time to wait for the connection attempt, in milliseconds. If set to 0, it will wait indefinitely. e、CURLOPT_DNS_CACHE_TIMEOUT sets the time to keep DNS information in memory, the default is120 seconds.
$ch = curl_init(); curl_setopt($ch, CURLOPT_URL,$url); curl_setopt($ch, CURLOPT_RETURNTRANSFER,1); curl_setopt($ch, CURLOPT_TIMEOUT,60); //You only need to set a number of seconds. curl_setopt($ch, CURLOPT_HTTPHEADER, $headers); curl_setopt($ch, CURLOPT_USERAGENT, $defined_vars['HTTP_USER_AGENT']);
This is the full content of the solution to set the timeout time for the PHP request remote address brought to you by the editor. I hope everyone will support and cheer for the tutorial~
