I am moving my company from a legacy service to a new system. I have written some conversion utilities in PHP to facilitate the move. One issue I am coming accross is converting the zip codes.
In the old system, Zips could be mixed in one line:
700,701,30518,30511,30000-30010,400,30097,30101-30201
In my new system, each type of zip must be broken into it's own line:
700,701,400
30518,30511,30097
30000-30010,30101-30201
So I need to import the first code block and output the second code block to 3 variables. I am working in PHP. Any Guidance? The order of the zips is random. I'm Lost.

Answer 1

Well, this is what I got:
/(\d+)(-\d+)?/s
/s is to ignore newlines.
<?php
$subject = "700,701,400\n30518,30511,30097\n30000-30010,30101-30201\n";
preg_match_all("/(\d+)(-\d+)?/s", $subject, $matches);
print_r($matches[0]);
?>
Here's output:
Array
(
[0] => 700
[1] => 701
[2] => 400
[3] => 30518
[4] => 30511
[5] => 30097
[6] => 30000-30010
[7] => 30101-30201
)
Alternatively, you can do this:
$arr = explode("\n", $subject);
for ($i = 0; $i < count($arr); $i++) {
preg_match_all("/(\d+)(-\d+)?/s", $arr[$i], $matches);
print_r($matches[0]);
}
If there's only three types, then you can just preg_match for each line.
Output:
Array
(
[0] => 700
[1] => 701
[2] => 400
)
Array
(
[0] => 30518
[1] => 30511
[2] => 30097
)
Array
(
[0] => 30000-30010
[1] => 30101-30201
)
Array
