php - Adding link tags and rel="lightbox" around images Regex -


how can change example when got <image> tag , want add link tags around them , rel lightbox attribute well? cant figure out. i'm not regular expressions @ all.

the example

$pattern ="/<a(.*?)href=('|\")(.*?).(bmp|gif|jpeg|jpg|png)('|\")(.*?)>/i"; $replacement = '<a$1href=$2$3.$4$5 rel="lightbox" title="'.$post->post_title.'"$6>';

so in case have <img src="...." class="...." alt=".....">

and need <a href="....." rel="lightbox" title="....."><img src="...." class="...." alt="....."></a> how change this? help.

it's unclear want here, utilize dom task instead.

$doc = domdocument::loadhtml('      <img src="www.foo.com/1.gif" class="foo" alt="...">      <img src="www.bar.com/1.jpg" class="bar" alt="...">      <img src="example.com/2.jpg" class="example" alt="...">    ');  foreach ($doc->getelementsbytagname('img') $node) {    $link = $node->ownerdocument->createelement('a');     $a = $node->parentnode->insertbefore($link, $node);     $a->setattribute('href', $node->getattribute('src'));    $a->setattribute('rel', 'lightbox');    $a->setattribute('title', 'some title');     $a->appendchild($node); }  echo $doc->savehtml();

output:

<a href="www.foo.com/1.gif" rel="lightbox" title="some title"><img src="www.foo.com/1.gif" class="foo" alt="..."></a> <a href="www.bar.com/1.jpg" rel="lightbox" title="some title"><img src="www.bar.com/1.jpg" class="bar" alt="..."></a> <a href="example.com/2.jpg" rel="lightbox" title="some title"><img src="example.com/2.jpg" class="example" alt="..."></a>
