Hello, how to set up a REGEX to get 2 groups of all the href link
<a href="/page/page/categoria/page?page=2&publica=1" rel="next">2</a>
Where group 1 would be the entire link
/page/page/categoria/page?page=2&publica=1
And the second group would be the page number (page = ? )
2
My REGEX by how much it looks like this:
href=["][^"]+page=(\d+).+["]
// GRUPO 1: href="/page/page/categoria/page?page=2&publica=1" rel="next"
// GRUPO 2: 2
Instead of regex you can use DOMDocument , a PHP API that works with XML and HTML , an example would look like this:
$conteudoDoHtml = '<a href="/page/page/categoria/page?page=2&publica=1" rel="next">2</a>';
$dom = new DOMDocument;
$dom->loadHTML($conteudoDoHtml);
$ancoras = $dom->getElementsByTagName("a");
foreach($ancoras as $elementos) {
echo $elementos->getAttribute('href'), '<hr>';
}
So you would only do one regex to extract page
$conteudoDoHtml = '<a href="/page/page/categoria/page?page=2&publica=1" rel="next">2</a>';
$dom = new DOMDocument;
$dom->loadHTML($conteudoDoHtml);
$ancoras = $dom->getElementsByTagName("a");
foreach($ancoras as $elementos) {
$data = $elementos->getAttribute('href');
echo 'Conteudo de href:', $data, '<br>';
preg_match('#(&|&|\?)page=(\d+)#', $data, $match);
echo 'page=', $data[2], '<br>';
var_dump($match);//Pra visualizar melhor o resultado do preg_match
echo '<hr>';
}
href="([^"]+\?(page=([^&]*))[^"]+)"

Basically, it captures the href that contains page. And subdivide the way you want it.
match[1] = toda url
match[2] = page=conteudo
match[3] = conteudo
