Curl Not Whole Content

[Guest]

Can I use curl to select only a certian amount of a page instead of the whole thing. I just would like it to get the first couple of lines like 25 can i do this.

 

I use this to get the whole page

$ch = curl_init();
curl_setopt($ch, CURLOPT_URL,"$url");
curl_setopt($ch, CURLOPT_RETURNTRANSFER,1);
$html=curl_exec ($ch);
curl_close ($ch);

Using curl, you can't. But if you can define what lines you want, maybe we can use the string functions to manipulate the result and return what we want.

You could use the stream/file functions to read from it as a socket, and stop at 25 lines.

So, something like:

$f = fopen('http://site.com/page.php','r');

for( $i=0;$i<25,!feof($f);$i++ )
{
    //Do something with line
    $line = fgets($f);
}

 

Probably not working code, I don't know the f* functions well for remote pages.

Yeah ShogunWarrior is right, you could use the file functions if you don't need to send post data and/or cookies (or any other stuff curl can do but the file functions can't).

 

<?php
$start_line = 10; //Set here the line to start from (first line is 0)
$amount = 11; // The amount of lines you want to read
$url = "http://www.TheDataYouNeed.com/file.txt"; //The file
//This example fetches lines 10 to 20

$end_line = $start_line + $amount;
$lines = file($url);
$count = count($lines);

$limit = ($count > $end_line) ? $end_line : $count;
$result = "";
for($i = $start_line; $i <= $limit; $i++)
$result .= $lines[$i];

echo $result;

?>
