Question

I have string as abvd.qweqw.sdfs.a=aqwrwewrwerrew. I need to parse this string and get piece before = and after =. Symbol . can occur many times. So, please, tell me, which regular expression can I use for parsing? Thank you.

Answer 1

Purely based on your example:

/([a-z.]+)=([a-z]+)/

Edit

But actually:

/([a-z_.]+)=(.*)/i

The results are in memory groups 1 and 2. In code:

if (preg_match('/^([a-z_.]+)=(.*)/i', $str, $matches)) {
    // $matches[1] contains part before =
    // $matches[2] contains part after =
}

Btw, I’ve tweaked the expression by anchoring it (using ^). If that doesn’t work, just remove it from the expression.
