How does php write a regular expression to retrieve the [attach] 1 [attach] content [attach] 1 [/attach] att[ attach] 2 [/attach] your part?

How to obtain the array of content 1 and 2 between [attach] [/attach]

Reply to discussion (solution)

Preg_match_all ('/[attach] (. *?) [/Attach]/I ',' [attach] 1 [/attach] [attach] 2 [/attach] ', $ out ); print_r ($ out );

Not tested!

/[attach](.*?)[\/attach]/i

Just forgot to write the escape

It seems wrong, big brother. how can I output the results?

The output is
1
2

Preg_match_all ('/\ [attach \] (. *?) \ [\/Attach \]/I ',' [attach] 1 [/attach] [attach] 2 [/attach] your ', $ out ); print_r ($ out );

I want to test it for you!

The above arrays are all out, and the rest will be done by yourself.

$ Str = "content [attach] 1 [/attach] [attach] 2 [/attach] your"; preg_match_all ('/\ [attach] (. *?) \ [\/Attach]/I ', $ str, $ ret); print_r ($ ret [1]);

Output:
Array ([0] => 1 [1] => 2)
