A few questions about cURL

[AHA7]

Hello,

 

I have a few questions about cURL, please!

 

1- I want to use cURL in a loop to open a few documents. Do I have to put the two functions curl_init() and curl_close() inside the loop or I can put them outside. Notice that in each iteration of the loop a different document is opened.

Example, is the following correct:

 

$ch = curl_init(); //This is outside the loop

for($i=1; $i <= $filecount; $i++)

{

$path = ${'file_location_' . $i};

curl_setopt($ch, CURLOPT_URL, $path); //The handle $ch was set outside the loop.

.

.

.

curl_exec($ch);

}

curl_close($ch); //This is outside the loop

 

2- In the loop above if CURLOPT_CONNECTTIMEOUT was set to 5 (timeout after 5 seconds), and say in the third iteration of the loop the connection times out and it fails to connect to the site, then what would happen? Would other curl_setopt() functions and the function curl_exec() be executed or not?

 

3- What does the function curl_setopt ($ch, CURLOPT_CONNECTTIMEOUT, 5) return when the connection times out and it fails to connect to resource? Can I use the returned value to display a customized error message when the connection times out?

maybe you should run some tests!

 

edit reading the manual also helps

I did read the mannual, but they didn't specifically say anything about what curl_setopt ($ch, CURLOPT_CONNECTTIMEOUT, VALUE) returns when the connection times out. I have also tried to do some tests but the connection seemed to always succeed. Could not make it time out.

if you want to make a page that times out, build soemthing with a loop that loops 10k times, etc... then see what happens.

 

I believe it just returns nothing, $string="";
