cURL

Hey,

Was just wondering if this little bit of code could be converted to a cURL function instead of File_get_contents, a little but stumped about how to do that with this code, was wondering if anyone could do it? thanks.

PHP Code:


		
			
    function file_get_content( $url )

    {

        for( $i = 1; $c <= $this->conf['tries']; $c++ )

        {

            $file = @file_get_contents( $url );

            if( $file != FALSE )

            {

                return array( 1 => TRUE, 2 => $file );

                break;

            }

        }

        return array( 1 => FALSE, 2 => '' ); 

    }

This is how to use cURL to grab a file

PHP Code:


		
			
/*First we Initialize a new cURL session and pass in our url,
then it returns a cURL handle */
$ch = curl_init("http://www.blahblah.com/file.txt");

/*We must set CURLOPT_RETURNTRANSFER to true otherwise it just farts
 it out to screen instead of putting it into $file when we run curl_exec()*/
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);

//Execute and put contains in $file
$file = curl_exec($ch);

//close the cURL session
curl_close($ch);

Hope that helps

Would that work with the rest of the code though?

should do:

PHP Code:


		
			
function file_get_content( $url )
{
    for( $i = 1; $c <= $this->conf['tries']; $c++ )
    {
        $ch = curl_init($url);

        curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
        
        $file = curl_exec($ch);//Returns file contents string, FALSE on failure
        
        curl_close($ch);

        if($file)
        {
            return array( 1 => TRUE, 2 => $file );
            break;
        }
    }
    return array( 1 => FALSE, 2 => '' );
}

I havent tested it, but theoreticly it should work.

Why do you want to use cURL anyway? I think Salathe pointed out a good way to get the HTTP headers in an earlier thread of yours.

I would recommend doing as above, but put the curl call into a function and name it like file_get_contents_curl or something, easier to understand then and more portable.

Do you have the cURL extension installed? It needs to be installed to have cURL functionality in your website.

I've modified it only slightly, but this works perfectly for me:

PHP Code:


		
			
function file_get_content( $url )
{
    for($i = 1; $i <= 3; $i++)
    {
        $ch = curl_init($url);

        curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
        
        $file = curl_exec($ch);//Returns file contents string, FALSE on failure
        
        curl_close($ch);

        if($file)
        {
            return array( 1 => TRUE, 2 => $file );
            break;
        }
    }
    
    return array( 1 => FALSE, 2 => '' );
}  

var_dump(file_get_content('http://www.wiredflame.com/'));

what exactly do you mean, does it produce an error? also ive just noticed somthing a bit 'iffy' in your for loop (didnt actually check it through when i looked last, i just replaced file_get_content() with cURL)

PHP Code:


		
			
 for( $i = 1; $c <= $this->conf['tries']; $c++ )

should that not read:

PHP Code:


		
			
 for( $i = 1; $i <= $this->conf['tries']; $i++ )

dunno if that was your problem, i dunno what the rest of your script looks like so i might be off the mark so to speak.
