Is it possible to kill/stop multi curl requests if one of the requests receives the status code 429?
I've been trying to find a solution to this as I pull data from an API and need to avoid going over the rate limit.
These requests are asynchronous so I'm unsure how I would do this.
well, you should be able to cancel them at will with a CURLOPT_PROGRESSFUNCTION, have a global variable for wether or not to cancel transfers, a function that import it (with the global $var syntax), and make it return 1 when its time to cancel, eg $abort=false;ecurl_setopt($ch,CURLOPT_PROGRESSFUNCTION,function($a,$b,$c,$d,$e){global $abort;return (int)!$abort;}); - then just make $abort=true; when its time to abort them. that said, you can use CURLOPT_MAX_RECV_SPEED_LARGE to limit the speed of the transfers, if its a speed rate limit you're exceeding
edit: note that you also need to set CURLOPT_NOPROGRESS to false for CURLOPT_PROGRESSFUNCTION to be called at all.
