If I have a111Ta222T
I wish to extract in PHP a111T
The point is to stop match at the first occurence of T, instead of at the last T.
How can I do this using regex?
I don't wish to use a[\S]+(?=a)
which can have the same result a111T

2Why you do not wish to use `a[\S]+(?=a)` if it works? – Jens Jun 09 '15 at 05:34

@Jens: Probably because it won't work for longer instances. – nhahtdh Jun 09 '15 at 05:38

The question is too broad as is - there are many different ways to extract the data. It can be as strict as `a\d+T` or as liberal as `[^T]+T`. – nhahtdh Jun 09 '15 at 05:40

Use non greedy +?
/a.+?T/
Test
preg_match('/a.+?T/', 'a111Ta222T', $matches);
echo $matches[0]
=> a111T

^a\S+?T
You can simply do this.+? is non greedy and will stop at the first instance of T.You would also want to ^ anchor your string in order to stop at first T.

you can use this regex
[^T]+T
check this Demo
if you want your match to start with letter a you can use a[^T]+T
