How to fetch Image using PHP

Hi

I want to add some features in my new site. which fetch image and content automatically from the any url which is entered like digg. so can any one help me for that.

 

Hi,

On dig what happens is users share the information that gets stored in the database of dig and then shown on its website. You can do this or if you do not want to save the information in your database you can use the file and CURL functions of PHP that will read the content of a URL passed and using regular expressions fetch the details or data you need from that website.

Thanks for reply

will you pl provide me the script if you have

 

It's easy to download any webpage using curl:

<?php
$curl = curl_init();
curl_setopt ($curl, CURLOPT_URL, "http://www.webpage.com");
curl_setopt($curl, CURLOPT_RETURNTRANSFER, 1);
$result = curl_exec ($curl);
curl_close ($curl);
echo $result;
?>

The output lays in $result, you can parse it further to extract any info you need.

 

or use file_get_contents() and parser the image tags

 

thanks for help

for images (without content)

<?php
$sFile = "http://www.google.com/intl/en_ALL/images/logo.gif";
$imagedata = GetFileData($sFile);
ob_start();
$length = strlen($imagedata);
header('Last-Modified: '.date('r'));
header('Accept-Ranges: bytes');
header('Content-Length: '.$length);
header('Content-Type: image/gif');
print($imagedata);
ob_end_flush();
function GetFileData($sFilePath){
    $fp = fopen($sFilePath, 'rb') or die('404! Unable to open file!');
    $buf = '';
    while(!feof($fp)){
        $buf .= fgets($fp, 4096);
    }
    fclose($fp);
return $buf;
}
?>

PHP:

you can change the header to

header('Content-Type: image/gif');

to image/png or jpg (jpeg) etc for different pic formats

You can use bellow code, it can download any files :

function downloadFile($url, $path)
{
  $newfname = $path;
  $file = fopen ($url, "rb");
  if ($file) {
    $newf = fopen ($newfname, "wb");

    if ($newf)
    while(!feof($file)) 
    {
      fwrite($newf, fread($file, 1024 * 8 ), 1024 * 8 );
    }
  }

  if ($file) 
  {
    fclose($file);
  }

  if ($newf) 
  {
    fclose($newf);
  }
}
downloadFile('http://i.dpstatic.com/icon/icon4.png','icon4.png');
