preg_match scheme error

[Synchro]

Can you provide test cases to show what this fixes please?

I've had more of a look at this: removing that : will break IPv6 literals, which is why it's there along with [ and ]. The match is not terribly thorough, but it's not meant to be.

When i use ssl://smtp.name.it:25;tls://smtp.test2.it:586
The script creates this situation:
Connection: opening to tls://smtp.test2.it:586:25, timeout=300, options=array (....

It does not find the fourth optional parameter (port) and add the standard port.

This is for domain name. For ipv6, i think i need to make a special regex

For this:
^((ssl|tls):\/\/)*([a-zA-Z0-9\.-]*):?([0-9]*)$

I have:

Full match | 0-23 | tls://smtp.test2.it:586
Group 1. | 0-6 | tls://
Group 2. | 0-3 | tls
Group 3. | 6-19 | smtp.test2.it
Group 4. | 20-23 | 586

For this:
^((ssl|tls):\/\/)*([a-zA-Z0-9:\[\]\.-]*):?([0-9]*)$

I have:

Full match | 0-23 | tls://smtp.test2.it:586
Group 1. | 0-6 | tls://
Group 2. | 0-3 | tls
Group 3. | 6-23 | smtp.test2.it:586
Group 4. | 23-23 | null<------that is the question

@eros23 You should find this is fixed now, and released as 5.2.24. I changed it to check for IPv6 separately.
