I need to find specific part of text in string. That text need to have:
- 12 characters (letters and numbers only)
- whole string must contains at least 3 digits
- 3*4 characters with spaces (ex.
K9X6 6GM6 LM11
) - every block from example above must contains at least 1 number
- words like
this
,line
,spod
shouldn't be recognized
So I ended with this code:
preg_match_all("/(?<!\S)(?i:[a-z\d]{4}|[a-z\d]{12})(?!\S)/", $input_lines, $output_array);
But it won't works for all of requirements. Of course I can use preg_repace
or str_replace
and remove all (!,?,#) and in a loop count numbers if there are 4 or more but I wonder if it is possible to do with preg_match_all
...
Here is a string to search in:
?K9X6 6GM6 LM11 // not recognized - but it should be
!K9X6 6GM6 LM11 // not recognized - but it should be
K0X6 0GM7 LM12! // not recognized - but it should be
K1X6 1GM8 LM13@ // not recognized - but it should be
K2X6 2GM9 LM14? // not recognized - but it should be
K3X6 3GM0 LM15# // not recognized - but it should be
K4X6 4GM1 LM16* // not recognized - but it should be
K5X65GM2LM17
bla bla bla
this shouldn't be visible
spod also shouldn't be visible
but line below should be!!
K9X66GM6LM11! (see that "!" at the end? Help me with this)
Correct preg_match_all
should returns this:
K9X6
6GM6
LM11
K9X6
6GM6
LM11
K0X6
0GM7
LM12
K1X6
1GM8
LM13
K2X6
2GM9
LM14
K3X6
3GM0
LM15
K4X6
4GM1
LM16
K5X65GM2LM17
K9X66GM6LM11
