 Re: How to fetch Image using PHP

The code on this page displays an image selected at random using PHP.  The list of images for this example comes from a directory listing.

The code for this example:

Code:

<?php 
function getRandomFromArray($ar) { 
    mt_srand( (double)microtime() * 1000000 ); 
    $num = array_rand($ar); 
    return $ar[$num]; 
} 

function getImagesFromDir($path) { 
    $images = array(); 
    if ( $img_dir = @opendir($path) ) { 
        while ( false !== ($img_file = readdir($img_dir)) ) { 
            // checks for gif, jpg, png 
            if ( preg_match("/(\. gif|\. jpg|\. png)$/", $img_file) ) { 
                $images[] = $img_file; 
            } 
        } 
        closedir($img_dir); 
    } 
    return $images; 
} 

$root = ''; 
// If images not in sub directory of current directory specify root  
//$root = $_SERVER['DOCUMENT_ROOT']; 

$path = 'images/'; 

// Obtain list of images from directory  
$imgList = getImagesFromDir($root .  $path); 

$img = getRandomFromArray($imgList); 

?>

Place the following where you wish the random image to appear:
<img src="<?php echo $path .  $img ?>" alt="" />

Try this may be it help full to you.

Code:

function save_image($img,$fullpath){
    $ch = curl_init ($img);
    curl_setopt($ch, CURLOPT_HEADER, 0);
    curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
    curl_setopt($ch, CURLOPT_BINARYTRANSFER,1);
    $rawdata=curl_exec($ch);
    curl_close ($ch);
    if(file_exists($fullpath)){
        unlink($fullpath);
    }
    $fp = fopen($fullpath,'x');
    fwrite($fp, $rawdata);
    fclose($fp);
}

Code:

<?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.

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)){
