Here is my code:
$content2= preg_replace("/<([a-z][a-z0-9]*)[^>]*?(\/?)>/i",'<$1$2>', $content1);
This code removes all attributes from all tags in my website, but what I want is to only remove attributes from the form tag. This is what I have tried:
$content2 = preg_replace("/<form([a-z][a-z0-9]*)[^>]*?(\/?)>/i",'<$1$2>', $content1);
and
$content2 = preg_replace("/<(form[a-z][a-z0-9]*)[^>]*?(\/?)>/i",'<$1$2>', $content1);
分享 This should do it for you.
<?php
$content1 = '<form method="post">test</form><form>2</form><form action=\'test\' method="post" type="blah"><img><b>bold</b></form>';
$content2 = preg_replace("~<form\s+.*?>~i",'<form>', $content1);
echo $content2;
Output:
<form>test</form><form>2</form><form><img><b>bold</b></form>

The \s+ is requiring whitespace after the opening form tag if we have that we presume there is an attribute after so we use .*? which takes everything until the next >. We don't need capture groups because the only thing you want is an empty form element, right?
