How to get href value from string

Question

I'm trying to get the href from this string, but I can't because it has space inside the link. I try to do it from regex but I'm not an expert in regex. I tried using an example from the internet but I didn't get the value I was after.

A better way to parse HTML is to use DOMDocument. You can use it to process your HTML and find the hrefs from all the tags in your HTML. I'm assuming your HTML is in a variable called $html:

$doc = new DOMDocument();
$doc->loadHTML($html);
$anchors = $doc->getElementsByTagName('a');
foreach ($anchors as $a) {
    $urls[] = $a->attributes->getNamedItem('href')->nodeValue . "
";
}
foreach ($urls as $url) {
    echo $url;
}

Output

DetailResults.aspx?sid=90651&id=1769095&nsub= [Project Quality] &Subjectid=1561 
DetailResults.aspx?sid=90898&id=1769088&nsub= [Project Costs] &Subjectid=1559

If you have to use regex, this will work for your sample data:

preg_match_all('/href="([^"]+)/', $html, $matches);
print_r($matches[1]);

Output:

Array ( 
    [0] => DetailResults.aspx?sid=90651&id=1769095&nsub= [Project Quality] &Subjectid=1561
    [1] => DetailResults.aspx?sid=90898&id=1769088&nsub= [Project Costs] &Subjectid=1559 
)
