PHP - Moved: (simple) Escaping In Regex?

Quote from: Mike Solstice on April 14, 2011, 12:24:45 AM

Ok, that works if I run it CLI or though phpMyAdmin, but won't if I try it in php

Code: [Select]
$remcomma = "UPDATE top_train SET deaths = replace( replace(field_name, ',', ''), '"', '' )";
mysql_query($remcomma);

I assume because of the quotes used in the regex. I tried escaping the "

Code: [Select]
$remcomma = "UPDATE top_train SET deaths = replace( replace(field_name, ',', ''), '\"', '' )";
mysql_query($remcomma);

Which broke it altogether. Anyone have any ideas?

Thanks!



Moved here since that thread was marked as solved & it's more of a PHP issue at this point anyway. Any & all help is greatly appreciated!

Hi Guys. This should- hopefully- be a pretty simple question for someone with regex experience to answer. I've been reading all the regex guides and tried various things but none have worked and I'm starting to get a headache. I've decided to just pitch the question here.

How do I test if a string contains ONLY a certain character- but could be one or more instances of that character. In this case it's a comma. So:

','           -> Would return TRUE
',,,'         -> Would return TRUE
',,,,,,,'     -> Would return TRUE

',,,hello,' -> Would return FALSE
'hi,,,'       -> Would return FALSE


Thanks in advance!
