how can I extract the post image from this link using php?
I read that I can't do it with regex.
Thank you so much.

$content=file_get_contents($url);
if (preg_match("/<img.*src=\"(.*)\".*class=\".*pinit\".*>/", $content, $matches))
{
echo "Match was found <br />";
echo $matches[0];
}
$matches[0] will print the whole image tag. And if you want to extract only the URL, then you can use $matches[1] to get the same :)

I'm trying to do the same for "techcrunch.com/2014/05/09/facebook-is-down-for-many" but it doesn't return anything. I know the <img> lies here :<img src="tctechcrunch2011.files.wordpress.com/2014/05/…" class="" /> but even after few changes it doesn't return anything. Any help would be nice _/_

That regex was very specific for the pattern in that particular web page. Try this. if (preg_match("/<img.*src=\"(.*)\"/", $content, $matches)) { echo "Match is found <br />"; echo $matches[0]; } Working : The regex will go in search for a src attribute within the image tag, then extracts the image URL that is assumed to be within double quotes. You can modify it as of your requirements.
You can/must parse your html with DOM, here is example with your case:
$curlResource = curl_init('http://www.huffingtonpost.it/2013/07/03/stupri-piazza-tahrir-durante-proteste-anti-morsi_n_3538921.html?utm_hp_ref=italy');
curl_setopt($curlResource, CURLOPT_RETURNTRANSFER, true);
curl_setopt($curlResource, CURLOPT_FOLLOWLOCATION, true);
curl_setopt($curlResource, CURLOPT_AUTOREFERER, true);
$page = curl_exec($curlResource);
curl_close($curlResource);
$domDocument = new DOMDocument();
$domDocument->loadHTML($page);
$xpath = new DOMXPath($domDocument);
$urlXpath = $xpath->query("//img[@id='img_caption_3538921']/@src");
$url = $urlXpath->item(0)->nodeValue;
echo $url;
Take your time and learn a little DOM and XPATH it's worth it.

Try This ...
$content=file_get_contents($url);
if (preg_match("/src=[\"\'][^\'\']+[\"\']/", $content, $matches))
{
echo "Match was found <br />";
echo $matches[0];
}
