Simple Regular Expression

$ Str = "abcde1234 ";
Preg_match ('/^ (\ w +) e (\ d +) $/I', $ str, $ matches );

Print_r ($ matches );

Array
(
[0] => abcde1234
[1] => abcd
[2] => 1234.
)

Explode () function http://www.w3school.com.cn/php/func_string_explode.asp

  Abcd [1] => 1234)

Regular Expressions can also achieve more complex segmentation.
