Question

I am attempting to remove some line breaks and spaces from a multiline string I have, such as the following:

    Toronto (YTZ)
    to
    Montreal (YUL)

I tried doing:

$matched = preg_replace('/[\n]/', '', $string);
var_dump($matched);

but all it returns is:

    Montreal (YUL)

I’ve tried all sorts of combinations of regular expressions, but it only ever seems to find what I specify, replace it, and display anything AFTER the matched expression.

I’m sure it’s something simple, but I can’t seem to figure it out.

Thanks in advance!

Answer 1

\n only represents “go to line” if it is between double quotes in PHP “\n”… Your regex should be "/[\n]/" not '/[\n]/'

Anyway, don’t use a regular expression for that, but str_replace("\n",'',$string) instead. It’s faster.
