Help with expression

[ngreenwood6]

I came up with this solution all on my own knowing no regex at all

 

'/(\[)(adapter)(=\")(.*)(\"\])/i'

 

All I wanted this to do was match this: [adapter=test] or this:[adapter=""].

 

I was just wondering if there is a better way to do this and to match it on this as well [adapter] because currently it wont match that.

Something like:

 

'/\[adapter[="]*(.*?)["]?\]/i'

 

Should match:

 

[adapter=test]

[adapter=""]

[adapter]

[adapter=test]

[Adam]

Try: '/\[adapter(?:=")?(.*?)"?\]/i'

 

Edit

 

Or if you want to enable single or double quotes, but make sure they match:

 

preg_match('/\[adapter(?:=(["\']))?(.*?)\\1\]/i', $str, $matches, PREG_OFFSET_CAPTURE)
