Regular efficiency is too low there is no way to replace it with other alternatives

To format the ab100bc200cd300 string as ab=>100, bc=>200, cd=300, which is the English + number
Although the use of regular is possible, but inefficient performance is too low, there is no way to achieve with other parties? Ask the Great God for answers

$s = ' ab100bc200cd300 ';p reg_match_all ('/([a-z]+) (\d+)/', $s, $m); $t = Array_combine ($m [1], $m [2]);p Rint_r ($t);

Array (    [AB] = [    BC] = [    cd] = 300)

Low efficiency? I didn't see it.

With the moderator this method, the efficiency seems high. It seems that the optimization of the code is important.
