PHP - 换行符和删除BR

Question

I have a string

"PRINT CHIFFON<BR /><BR />

"

I am trying to remove any newline symbols and
tags.

$i->colour_code = str_replace('<br>', '', strip_tags($i->colour_code));
$i->colour_code = str_replace('<br \/>', '', strip_tags($i->colour_code));
$i->colour_code = preg_replace("/[
]/","",$i->colour_code); 

That still does not work. Any ideas will be appreciated as this issue causes the whole system stop working

Answer 1

You don't need to escape the slash in the second line of replacements. In fact, since you're running it through strip_tags, you don't even need the first two replacements. Try this:

$i->colour_code = str_replace(Array("
",""),"",strip_tags($i->colour_code));

Just make sure that $i->colour_code is not readonly.
