Is it possible to replace an upper-case with lower-case using preg_replace
and regex
?
For example:
The following string:
$x="HELLO LADIES!";
I want to convert it to:
hello ladies!
using preg_replace()
:
echo preg_replace("/([A-Z]+)/","$1",$x);
I think this is what you are trying to accomplish:
$x="HELLO LADIES! This is a test";
echo preg_replace_callback('/\b([A-Z]+)\b/', function ($word) {
return strtolower($word[1]);
}, $x);
Output:
hello ladies! This is a test

If you just want the whole string to be lowercase though than just use strtolower
on the whole thing.
