I am trying to create a regex pattern to find and then replace my IMG src tags in my HTML template.
Essentially, the pattern should find the contents of the src:
And then replace it as such: none
In above code source is always same data-lazy-src is chnaging
I'll agree that regex isn't necesarily the right way to do this. Here is a solution using the HTML Dom parser:
$html = 'your markup';
$doc = new DOMDocument();
$doc->loadHTML($html);
$tags = $doc->getElementsByTagName('img');
if(count($tags) > 0) {
$tag = $tags->item(0);
$tag->setAttribute('src', $new_src_url);
$doc->saveHTML($tag);
}
Then, $doc
should have your updated markup with the src atributes of your images changed.
尝试如下操作:
preg_replace('/(<img.*) src=\"[^"]*\"(.*>)/', '$1 src="none"$2', $html)
