Cum descarci o imagine cu PHP

[AnoniMouse]

Salut!
Vreau sa descarc o imagine cu PHP dintr-un url.
Problema este ca url-ul respectiv cu imaginea este disponibil doar in "<img tag" nu si direct pe link-ul respectiv.
Trebuie mascat header-ul cumva? sa para ca requestul vine de la un tag img? sau cum se procedeaza.
multumesc!

O idee.

In img tag presupun ca are un nume, titlul plus extensie nu?
Mergi in inspect element si vezi calea la imagine, cea reală.
Apoi cu php adaugi id / nume la img la link.

How to extract img src, title and alt from html using php?

I would like to create a page where all images which reside on my website are listed with title and alternative representation. I already wrote me a little program to find and load all HTML files,...

n-ai inteles, ce a zis el este hotlink protection, in general este bazata doar pe http referrer, dar poate avea si sesiuni, etc. depinde de site.


* Get referer inside php file_get_contents
* posibil sa mai trebuiasca si user-agent. adaugi in same array, dupa \r\n, urmat de \r\n ca si primul
* astept pm cu site-ul daca nu reusesti.

O idee simpla...

Asa iti listeaza toate imaginile:

$url="http://example.com";

$html = file_get_contents($url);

$doc = new DOMDocument();
@$doc->loadHTML($html);

$tags = $doc->getElementsByTagName('img');

foreach ($tags as $tag) {
       echo $tag->getAttribute('src');
}

Iar daca vrei sa downloadezi imagini cu php, poti face in mai multe feluri, dar uite 2 exemple:

1.

$url = 'http://example.com/image.php';
$img = '/my/folder/flower.gif';
file_put_contents($img, file_get_contents($url));

2.

$ch = curl_init('http://example.com/image.php');
$fp = fopen('/my/folder/flower.gif', 'wb');
curl_setopt($ch, CURLOPT_FILE, $fp);
curl_setopt($ch, CURLOPT_HEADER, 0);
curl_exec($ch);
curl_close($ch);
fclose($fp);

Personal eu prefer cURL, dar totul depinde de tine si ce vrei sa faci.

Sper sa te ajute!

Pe direct nu merge, doar in "<img"

1. file_get_contents () - This function is used to read the image file from URL and return the content as a string.
2. file_put_contents () - This function is used to write remote image data to a file.
