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.

<table class="grid border" cellspacing="0" border="0" id="ctl00_ContentBody_grvStudentResult" style="width:100%;border-collapse:collapse;">

<tbody>

    <tr>

        <th align="left" valign="middle" scope="col">Code</th>

        <th align="left" valign="middle" scope="col">Subject</th>

        <th align="left" valign="middle" scope="col">Status</th>

        <th align="center" valign="middle" scope="col">Score</th>

        <th align="center" valign="middle" scope="col">Result Date</th>

    </tr>

    <tr class="detail1">

        <td align="left" valign="middle">

        </td>

        <td align="left" valign="middle">

            <span class="">

            <a onclick="return hs.htmlExpand( this, {  objectType: 'iframe', width: 800, height: 600,  outlineWhileAnimating: true, preserveContent: false } )" href="DetailResults.aspx?sid=90651&amp;id=1769095&amp;nsub= [Project Quality] &amp;Subjectid=1561" title="Approved ">

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 <a> 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 . "n";

}

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 

)

I'm not expert but this work for me

$string ='<a onclick="return hs.htmlExpand( this, {  objectType: 'iframe', width: 800, height: 600,  outlineWhileAnimating: true, preserveContent: false } )" href="DetailResults.aspx?sid=90651&amp;id=1769095&amp;nsub= [Project Quality] &amp;Subjectid=1561" title="Approved "> 

            <img alt="" style="display: online" src="../Images/Common/r_Approved.gif" border="0">

            [Project Quality]   </a>';

preg_match_all( '~<a .*?href=['"](.*?)['"].*?>~', $string, $match );



$urls=array();//array of link

foreach($match as $m){

 if (isset($m[0])) {

    $url= $m[0];

}}
