Global Matching, Perl, Regular Expressions, /g Flag
Global matching in Perl refers to the use of the /g modifier in regular expressions, which allows a pattern to match multiple occurrences within a string, rather than stopping after the first match. 

$input = "Perl is great. Perl is versatile.";
@matches = ($input =~ /Perl/g);
print "Matches found: " . scalar(@matches); // Outputs: Matches found: 2
