Removing non alphanumeric character with some exceptions

I've came across this function that will do the first part I think

preg_replace("/[^A-Za-z0-9 ]/", '', $string);

But I don't want to remove '-','+' or '|'. How can I make exceptions for these.

Add with \char

preg_replace("/[^A-Za-z0-9 \-\+\|]/", '', $string);

You can also use the short form with \w

preg_replace("/[^\w\+\|\-\s]/", '', $string);

Try this :

$string  = "abcdAbcd-0999345@dfsdf%+";
echo preg_replace("/[^A-Za-z0-9\+\-\| ]/", '', $string);
