preg_match_all How to get all links? - php

Question

I'm trying to get all images links with preg_match_all those that begin with http://i.ebayimg.com/ and ends with .jpg , from page that I'm scraping.. I Can not do it correctly... :( I tried this but this is not what i need...:
preg_match_all('/(http|https|ftp|ftps)\:\/\/[a-zA-Z0-9\-\.]+\.[a-zA-Z]{2,3}(\/\S*)?/', $contentas, $img_link);
Same problem is with normal links... I don't know how to write preg_match_all to this:
<a class="link--muted" href="http://suchen.mobile.de/fahrzeuge/details.html?id=218930381&daysAfterCreation=7&isSearchRequest=true&withImage=true&scopeId=C&categories=Limousine&damageUnrepaired=NO_DAMAGE_UNREPAIRED&zipcode=&fuels=DIESEL&ambitCountry=DE&maxPrice=11000&minFirstRegistrationDate=2006-01-01&makeModelVariant1.makeId=3500&makeModelVariant1.modelId=20&pageNumber=1" data-touch="hover" data-touch-wrapper=".cBox-body--resultitem">
Thank you very much!!!

1. To capture src attribute starting by http://i.ebayimg.com/ of all img tags :
regex : /src=\"((?:http|https):\\/\\/i.ebayimg.com\\/.+?.jpg)\"/i
Here is an example :
$re = "/src=\"((?:http|https):\\/\\/i.ebayimg.com\\/.+?.jpg)\"/i";
$str = "codeOfHTMLPage";
preg_match_all($re, $str, $matches);
Check it in live : here
If you want to be sure that you capture this url on an img tag then use this regex (keep in mind that performance will decrease if page is very long) :
$re = "/<img(?:.*?)src=\"((?:http|https):\\/\\/i.ebayimg.com\\/.+?.jpg)\"/i";
2. To capture href attribute starting by http://i.ebayimg.com/ of all a tags :
regex : /href=\"((?:http|https):\\/\\/suchen.mobile.de\\/fahrzeuge\\/.+?.jpg)\"/i
Here is an example :
$re = "/href=\"((?:http|https):\\/\\/suchen.mobile.de\\/fahrzeuge\\/.+?.jpg)\"/i;
$str = "codeOfHTMLPage";
preg_match_all($re, $str, $matches);

If you want to be sure that you capture this url on an a tag then use this regex (keep in mind that performance will decrease if page is very long) :
$re = "/<a(?:.*?)href=\"((?:http|https):\\/\\/suchen.mobile.de\\/fahrzeuge\\/.+?.jpg)\"/i";

More handy with DOMDocument:
libxml_use_internal_errors(true);
$dom = new DOMDocument;
$dom->loadHTMLFile($yourURL);
$imgNodes = $dom->getElementsByTagName('img');
$result = [];
foreach ($imgNodes as $imgNode) {
$src = $imgNode->getAttribute('src');
$urlElts = parse_url($src);
$ext = strtolower(array_pop(explode('.', $urlElts['path'])));
if ($ext == 'jpg' && $urlElts['host'] == 'i.ebayimg.com')
$result[] = $src;
}
print_r($result);
To get "normal" links, use the same way (DOMDocument + parse_url).
