In Perl, string manipulation is typically done using string operators and built-in functions. Here are some commonly used string manipulation methods:

  1. Concatenating strings: Using the string operator “.” to combine two strings. For example:
my $str1 = "Hello";
my $str2 = "World";
my $result = $str1 . $str2;
print $result; # 输出HelloWorld
  1. get the length of an object
my $str = "Hello World";
my $len = length($str);
print $len; # 输出11
  1. Separate a string into substrings using a specified delimiter.
my $str = "apple,banana,orange";
my @arr = split(",", $str);
foreach my $item (@arr) {
    print $item . "\n";
}
  1. substitute
my $str = "Hello World";
$str =~ s/Hello/Hi/;
print $str; # 输出Hi World
  1. find()
my $str = "Hello World";
my $pos = index($str, "World");
print $pos; # 输出6

These are commonly used string manipulation methods in Perl, there are also many other string manipulation functions and modules that can be used. It is important to choose the appropriate method for manipulating strings based on specific needs.
