php regex to replace 'any' slashes in a path with directory separator

Question

I am trying to take paths like this:

some/path/here some\\other\\path

and replace each slash in the paths with PHP\'s DIRECTORY_SEPARATOR built in constant

Answer 1

Because you have 2 slashes try with #\\#

Answer 2

It should replace, not add. But try this:

preg_replace('/[\\]/', DS, $subject);

Should also work.

Answer 3

If you don't explicitly need regex, then this is the way:

$string = "some/path/here some\other\path";
$ds = DIRECTORY_SEPARATOR;
$result = str_replace(array("/","\\"),$ds,$string);
echo $result;

Outputs: some/path/here some/other/path

Answer 4

Rather than using preg_replace, why not just use str_replace?

$var = str_replace(array('/', '\\'), DIRECTORY_SEPARATOR, $subject);
