Question

Help! I’m doing a replace that will convert a bracketed block to a block surrounded by <div>s. Please see below.

The code:

$data = '
<p>
{ 
asdf
asdf
asdf
}
</p>
';

echo preg_replace('%{(.*)}%m', '<div>\1</div>', $data);

The output should be:

<p>
<div>
asdf
asdf
asdf
</div>
</p>

What am I doing wrong here?

Answer 1

Use the s modifier instead of the m modifier.

The s modifier allows . to match newlines.

The m modifier makes ^ and $ match the start and end of individual lines, as opposed to the start and end of the entire string.

Side-note: The preferred syntax for the replacement is <div>$1</div>
