[PHP] preg_match? Or something else?
I have an array that's created as follows: $string = 73G146C 311- 309.1C; $arr = preg_split(/[\s]+/, $string); Now I need to take each element in that array, and break them up even further so that I get: 73G= 73 and G 146C = 146 and C 311- = 311 and - 309.1C = 309, 1, and C (notice 3 elements here) I'm having a hard time trying to figure out what the proper regex would be for this, or whether that's the right thing to do. So far I've gotten this: preg_match(/^(?Plocation\d+)(?Pletter[A-Z-])/, $item, $matches); print_r($matches); Which gives me: Array ( [0] = 73G [location] = 73 [1] = 73 [letter] = G [2] = G ) Array ( [0] = 146C [location] = 146 [1] = 146 [letter] = C [2] = C ) Array ( [0] = 311- [location] = 311 [1] = 311 [letter] = - [2] = - ) Array ( ) However that's as far as it goes. For the other number it returns an empty array and I know why, the decimal point. Now I can evaluate each $item every time, see if they contain a decimal point, and pass it to a different regex string, but that seems rather inefficient to me. So how can I do this all in one fell swoop? Anyone want to take a stab at it?

73G= 73 and G

Which gives me:

[location] = 73
[1] = 73
[letter] = G
[2] = G

Array
(
[0] = 146C
[location] = 146
[1] = 146
[letter] = C
[2] = C
)
Array
(
[0] = 311-
[location] = 311
[1] = 311
[letter] = -
[2] = -
)
Array

Conditionals are your friend!
plaintext?php
$string = 73G146C 311- 309.1C;
$arr = preg_split(/[\s]+/, $string);
print_r($arr);
foreach ( $arr AS $item ) {
preg_match('|^(?Plocation\d+)\.?(?Pdecimal\d*)(?Pletter[A-Z-])|',
$item,
$matches);
print_r($matches);
}
?

or w/ preg_match_all:
?php
$regex = '/(([0-9]+)([^0-9])((?:[0-9]|\s+)))/';
$string = 73G146C 311- 309.1C;
preg_match_all( $regex , $string , $matches );
print_r( $matches )
