How can i use same regex for two different strings?

Question

hi have string,

$rt="Ability: B,Session: Session #2: Tues June 14th - Fri June 24th (9-2:00PM),Time: 9:30am,karthi";

$rt="Ability: B,Session: Session #2: Tues June 14th - Fri June 24th (9-2:00PM),Time: 9:30pm,karthi";

i used below regex for remove text from last comma(,).

$it_nme = preg_replace('/(?<=pm,)\S*/is', '', $rt);

it is worked for second string (because before comma have 'pm' text). for second one before comma we have string 'am'.

for both how can i write single regex?

As an aside: You really should learn at least the basics of regular expressions before using them in your code. — Tomalak

it replaces Fri June 24th (9-2:00PM) form here in string. but i need lowercase letter "pm".

@Ravichandran It should not replace the PM because the regex requires a , after the pm. To make the regex case-sensitive, remove the i modifier at the end.

You can use a regex OR like so:

$it_nme = preg_replace('/(?<=(pm|am),)\S*/is', '', $rt);
