i have text link

yeast-aid™ 200c - hypoallergenic

i want replace "200c" "200 caps" done on 20k records want , look able replace "c" prefixed number " caps".

i utilize php.

this basic regex substitution. seek programme out:

<?php $string = 'yeasties 200c - hyperhyperhyper'; echo preg_replace('/(\d)c/i', '$1 caps', $string); echo "\n"; ?>

preg_replace preforms regex substitution.

if cannot figure out how programme works, or want reference, seek php documentation here, preg_replace.

you should online documentation first. have never used php before (literally first programme it), didn't find challenging. perhaps of import coding skill beingness able larn things quickly.
