Cara menggunakan php default socket timeout

Timeouts are a rarely discussed topic and neglected in many applications, even though they can have a huge effect on your site during times of high load and when dependent services are slow. For microservice architectures timeouts are important to avoid cascading failures when a service is down.

The default socket timeout in PHP is 60 seconds. HTTP requests performed with for example file_get_contents, fopen, SOAPClient or DOMDocument::load are using this timeout INI setting to decide how long to wait for a response.

Since the socket/stream wait time is not included in PHPs max execution time you are in line for a surprise when requests take up to 30+60=90 seconds of your webservers precious processing queue before getting aborted.

Timeouts are scary, because you don’t know in what state you have left an operation when aborting. But in case of HTTP requests it is usually easy as a client to decide what to do:

1. Abort my own request and show the user an error
2. Ignore the timeout and just don’t display the data
3. Retry [a maximum of 3-5 times for example]

And configuring timeouts has other upsites:

• If the target server currently has load problems, then aborting with a timeout early could reduce the servers load by enough to automatically recover at some point.
• You can show users an error quickly and they don’t have to wait several seconds only to be taunted by an error page.

Setting the default timeout

Before doing anything else, you should decrease the default timeout early in your code to a value between 5 and 10 seconds:
