Question

I’m doing search engine for games titles in my database and I have some issue with that.

First, here’s the look on DB:

ID   TITLE
1     aaB
2     abc
3     ABC
4     AbdedABc
5     deff

Next, I’m doing this query:

SELECT g.title FROM game g WHERE g.title LIKE '%abc%'

All I want to do, is to print out all titles like this (with bold matches):

abc // match
ABC // match
Abded ABc // match last part, space added for clarity

For now, my script returns this:

str_replace('abc', '<b>abc</b>', $row['title'])

abc // matches
ABC
AbdedABc

Someone know any algorithm (or other way) to do not change letters upper/lower case?

Answer 1

I’m not sure what you wan’t to do but to match any combination of abc in upper or lowercase and make it bold you can do like this:

 $data = "testABC";
 echo preg_replace("/(abc)/i","<bold>$1</bold>",$data);
