Question

I’m having some difficulties in changing characters after a certain keyword (in this case it’s FOR) in a line that starts with SUM

Example:

SUM A+b+c TO var FOR D->E='' AND G->H=''

Expected Result:

SUM A+b+c To var FOR D:Field("E")='' AND G:Field("H")=''

Again any help/pointers will be greatly appreciated.

Thank you,

Andy

Answer 1

The replace itself can be achieved with the following:

<?php

$str = "SUM A+b+c TO var FOR D->E='' AND G->H=''";

print preg_replace('/([A-Z]+)->([A-Z]+)=([^\s]+)/', '\\1:Field("\\2")=\\3', $str);

(Example)

This does not, however, check that the string starts with SUM. You could incorporate a simple substr() check: if (substr($str, 0, 4) === 'SUM ') { ... }, see working demo.
