将“1小时19分钟”改为“1小时19分钟”

I have strings containing the runtime of movies:

1 h 19 min

Now I'd like it to look like this:

1h 19m

I know this should be actually pretty easy but I just don't manage to find a solution.

You can remove all spaces between a digit and a non-digit with a regular expression:

$str = preg_replace('/(?<=\d) *(?=\D)/', '', $str);

See it in action.

Update: Unfortunately this does not turn "min" into "m", which I didn't actually notice is desired.

In light of this, a str_replace solution with arrays such as bsdnoobz's is really the only sane way to go here. But just for the fun of it:

$str = preg_replace('/(?<=\d) *(\D)\S*/', '$1', $str);

See it in action.

$runtime="1 h 19 min";
$runtime=str_replace(" h","h",$runtime);
$runtime=str_replace(" min","m",$runtime);

$str = str_replace(array(' h', ' min'), array('h', 'm'), $str);

The easiest way

$runtime = "1 h 19 min";

$runtime = str_replace(" h", "h", $runtime);

$runtime = str_replace(" min", "min", $runtime);
