I'm trying to parse some html with PhpQuery, but it is not easy for me...
I need to extract only the URL(href tag) to an array but it is not working.
Please see this code for example purposes only:
$doc = phpQuery::newDocumentHTML('<div align = "left" style="background-color:#FFFFFF;border:1px solid #C3D9FF"> </p>

</div>');
//echo $doc['div table a']->attr('href');
foreach ($doc['div table a'] as $a) {
$hrefs[] .= pq($a)->attr('href');
}
print_r ($hrefs);
If I echo out the code bellow it get's me only the href url, and it is ok:
echo $doc['div table a']->attr('href');
If I run the foreach statement I got an array with some null values:
foreach ($doc['div table a'] as $a) {
$hrefs[] .= pq($a)->attr('href');
}
print_r ($hrefs);
The array I got is:
Array (
[0] => /1153414/
[1] =>
[2] => /1153399/
[3] =>
[4] => /1153280/
[5] =>
[6] => /1152665/
[7] =>
[8] => /1153524/
[9] =>
)
How can I generate an array like this:
Array (
[0] => /1153414/
[1] => /1153399/
[2] => /1153280/
[3] => /1152665/
[4] => /1153524/
)
If you can give me some clues, I would be appreciated.
Sorry my bad english
Best Regards,
You have five instances of <a/> in your code. This creates an empty a element, rather than closing an existing one. Remove them and your code should work fine.
Edit A very simple way of removing empty values from an array is running array_filter with no second argument:
$hrefs = array_filter($hrefs);
