Multiple curl_exec

[Blizzard84]

Are there any issues when executing multiple curl executions?
Calling the script below multiple times.

<?php
// create a new cURL resource
$ch = curl_init();

// set URL and other appropriate options
curl_setopt($ch, CURLOPT_URL, "http://www.example.com/");
curl_setopt($ch, CURLOPT_HEADER, 0);

// grab URL and pass it to the browser
curl_exec($ch);

// close cURL resource, and free up system resources
curl_close($ch);
?>

Thanks

Only server / connection load, IE, you are cURL'ing to 500 domains, it may time out due to the size of the response and the connection speed from your server to theirs.

What sort of issues are you talking about?

Hi,

Thanks for the quick reply!

Let's say I have a loop which calls a script 6 times.
http://www.example.com/addpass.php

This script adds a password to a file.

I've had some issues when sometimes the password wasn't updated.
Not sure if it timed out or not. Is it possible that the script wasn't finished before the next curl_init was called?

More information, the script below is ran multiple times.

<?php
// create a new cURL resource
$ch = curl_init();

// set URL and other appropriate options
curl_setopt($ch, CURLOPT_URL, "http://www.example.com/addpass.php");
curl_setopt($ch, CURLOPT_HEADER, 0);

// grab URL and pass it to the browser
curl_exec($ch);

// close cURL resource, and free up system resources
curl_close($ch);
?>

I would make my cURL request in to a function, and my addresses in to an array, then loop through the addresses.


Try something like this

<?php


function foreach_cURL($address){
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, $address);
curl_setopt($ch, CURLOPT_HEADER, 0);
curl_exec($ch);
curl_close($ch);
return true;
}


$addresses = array("http://www.example1.com/addpass.php", "http://www.example2.com/addpass.php", "http://www.example3.com/addpass.php");

foreach($addresses as $address){
if(!foreach_cURL($address)){
die("There was a cURL Error with \"{$address}\"");
}
}


?>

A little OT, but do you know how to use CURL to access a secure page (HTTP authentication - not HTTPS), and return the result, instead of outputting it? TIA
