regex / preg_match在数字和字母之间交替，并用空格分隔

Question

My string separates digits and alpha (phrases) by space. The digits and alpha alternate. So in the example below there are 6 ACT YE. And the string continues with another set of digit then alpha.

Can't seem to get the right pattern to do the following...

Example String: 6 ACT YE 1000 FH 6 ACT YE 10000 ACT FC 32000 ACT

Should come out like:

[0] = 6
[1] = ACT YE
[2] = 1000
[3] = FH
[4] = 6
[5] = ACT YE
[6] = 10000
[7] = ACT FC
[8] = 32000
[9] = ACT

Answer 1

Try this:

$result = preg_split("/(?<=\d)\s+(?=\D)|(?<=\D)\s+(?=\d)/",$input);

This splits the subject string on spaces, but only if exactly one of "the stuff before" and "the stuff after" is a digit.
