php - Remove All Strings Starting From The First Specific Character

Question

I have this kind of string: DURATION : 00:23:55.060000000

I want to convert it to this: 00:23:55.060000000

Please note that after DURATION, it has many spaces.

EDIT:

It seems that I made you upset, guys. :D

I did this and not working: preg_replace('/^Duration,\s+/', '', $result[20])

So, you've searched for lowercase, and your string is in uppercase... `preg_replace('/^Duration\s+: /i', '', $result[20])` — yivi, Jan 25 '17 at 08:41
You've already have **three** solutions just in the comments. Pick whatever. — yivi, Jan 25 '17 at 08:45
And what's with the comma in your regex. Use @yivi's solution (which he/she maybe should add as an answer ;). — SamWhan, Jan 25 '17 at 09:10

Your regex is messed up. You are looking for something in uppercase and your regex is in lowercase. And there is a comma laying around.

So if you rewrite that like:

preg_replace('/^Duration\s+: /i', '', $result[20])

(the i modifier after the regular expression says its case insenstive)

or:

preg_replace('/^DURATION\s+: /', '', $result[20])

It'll work.

But mostly, it seems that you want to catch the timestamp, and disregard the rest. For me, the code would be much clearer if your regex reflected that.

E.g.:

if (preg_match("|(?<timestamp>\d\d:\d\d\:\d\d\.\d{9})|", $string, $matches)) {
     echo $matches['timestamp'];
}

Solution :

$duration = substr($duration, strpos($duration, (":")) + 2);

I hope this can be useful for others who need it:

preg_replace('/duration|^(.*?):|\s/i', '', $result[20]);

code explanation: first, strip the duration, and then the first colon : lastly all spaces. put i at the end to the regex to declare that the search is incase-sensitive.

are you sure it is working? it is not working on my side. test it like this: `$var = "DURATION : 00:23:55.060000000";` `preg_replace('/^Duration\s+: /i', '', $var);` – Ari Jan 25 '17 at 09:31
