Question

need a simple preg_replace to convert all <br> <br/> and all possible br combinations to <br />.

This needs to work in order so i can process a string ie: $output = preg_replace( , <br /> , $input)

Thanks everyone!

Answer 1

One RegEx to rule them all:

$output = preg_replace( /<s*br[^>]*>/i ,  <br /> , $input);

Answer 2

[Obligatory HTML parser comment]

If you re working with unknown and non-consistent HTML (as it sounds like you are), then put down the regex, you might hurt yourself. Finding a list of tags and altering a document is what HTML parsers were built for.

Learn the PHP DOM Methods and save yourself a lot of heartache.

Answer 3

/< ?[bB][rR] ?/? ?>/

Answer 4

Try this pattern

<s*[bB][rR]s*/?s*>

Answer 5

$output = preg_replace( /< ?[bB][rR] ?/? ?>/ ,  <br /> , $input);
