Question

i have this string ++++++1DESIGNRESULTSM25Fe415(Main)

and i have similar string about 2000 lines from which i want to split these..

[++++++] [1] [DESIGNRESULTS] [M25] [Fe415] [(Main)]

from the pattern only the 2nd 4h and 5th value changes

eg.. ++++++2DESIGNRESULTSM30Fe418(Main) etc..

what i actually want is:

1. Split the first value [++++++]
2. Split the value after 4 Character of [DESIGNRESULTS] so ill get this [M25]
3. Split the value before 4 Character of [(Main)] so ill get this [Fe415]
4. After all this done store the final chunk of piece in an array.

the similar output what i want is

Array ( [0] => 1  [1] => M25  [2] => Fe415 ) 

Please help me with this…

Thanks in advance 🙂

Answer 1

Your data split needs are a bit unclear. A regular expression that will get separate matches on each of the chunks you first specify:

(\++)(\d)(DESIGNRESULTS)(M\d\d)(Fe\d\d\d)(\(Main\))

If you only need the two you are asking for at the end, you can use

(\d)DESIGNRESULTS(M\d\d)(Fe\d\d\d)

You could also replace \d\d with \d+ if the number of digits is unknown.

However, based on your examples it looks like each string chunk is a consistent length. It would be even faster to use

array(
   substr($string, 6, 1)
   //...
)
