I am using this regex expression:

String regex = '(\d11|\d5 \d6|\+\d12)';

Pattern compiledPattern = Pattern.compile(regex);

Matcher match = compiledPattern.matcher('Inbound Call at 5:10:54 PM from 07970123123 (Jack Daniels)');

if (match.matches()) 
 System.debug('MATCH');
 String phone = match.group(1);
 else 
 System.debug('MISS');

To extract the phone number from this String:

Inbound Call at 5:10:54 PM from 07970123123 (Jack Daniels)

When I test the Regex in:

Java Regular Expression Tester

regex101

It works fine.

But when I try and use it in Apex code, it does not find a match.

What am I doing wrong?

How can I fix it?

There is a difference between matches() and find() in apex. Mind adding your apex that isn't working?

The documentation on the Matcher class should shed some light here.

The description for matches() states the following

Attempts to match the entire region against the pattern.

Meanwhile the description for find() is

Attempts to find the next subsequence of the input sequence that matches the pattern. This method returns true if a subsequence of the input sequence matches this Matcher object's pattern.

find() is what you want to use here, since you want to match a portion of the input.

An example for illustration

String regex = '(\d11|\d5 \d6|\+\d12)';
Pattern msgPattern = Pattern.compile(regex);
Matcher m1 = msgPattern.matcher('Inbound Call at 5:10:54 PM from 07970123123 (Jack Daniels)');

system.debug(m1.matches()); // displays false
system.debug(m1.find()); // displays true

Matcher m = p.matcher(input);

System.debug('Find: ' + m.find()); // true
System.debug('Group: ' + m.group()); // 07970123123
System.debug('Matches: ' + m.matches()); // false

Matcher.matches() asks to find a match against the entire input region. Matcher.find() locates a group within the input region.
