Question

I am trying to update a config file from PHP using regexp. I cant seem to update digits.

This is my $contents:

$sugar_config['sysconfig_next_order_no'] = 'AAAAA';
$sugar_config['sysconfig_next_quote_no'] = '027827';

This is my $pattern:

/(.*sysconfig_next_order_no']\s=\s')(.*)(';)/

---

When I use all letters “AAAAAA” it works –

preg_replace($pattern, '$1AAAAAAA$3', $contents);

Result:

$sugar_config['sysconfig_next_order_no'] = 'AAAAAAA';
$sugar_config['sysconfig_next_quote_no'] = '027827';

When I use all numbers, it fails:

preg_replace($pattern, '$1123123$3', $contents);

Result:

23123';
$sugar_config['sysconfig_next_quote_no'] = '027827';

Can someone shed some light, I am forcing myself to always use regular expressions.

Answer 1

you have next_order_no in your regex – so it is only going to match the text with that key. It is not about numbers or letters – that is the red herring!
