In Perl, string manipulation is typically done using string operators and built-in functions. Here are some commonly used string manipulation methods:<\/p>\n

    \n
  1. Concatenating strings: Using the string operator “.” to combine two strings. For example:<\/li>\n<\/ol>\n
    my<\/span> $str1 = \"Hello\"<\/span>;\r\nmy<\/span> $str2 = \"World\"<\/span>;\r\nmy<\/span> $result = $str1 . $str2;\r\nprint<\/span> $result; # \u8f93\u51faHelloWorld<\/span>\r\n<\/code><\/pre>\n
      \n
    1. get the length of an object<\/li>\n<\/ol>\n
      my<\/span> $str = \"Hello World\"<\/span>;\r\nmy<\/span> $len = length<\/span>($str);\r\nprint<\/span> $len; # \u8f93\u51fa11<\/span>\r\n<\/code><\/pre>\n
        \n
      1. Separate a string into substrings using a specified delimiter.<\/li>\n<\/ol>\n
        my<\/span> $str = \"apple,banana,orange\"<\/span>;\r\nmy<\/span> @arr = split<\/span>(\",\"<\/span>, $str);\r\nforeach<\/span> my<\/span> $item (@arr) {\r\n    print<\/span> $item . \"\\n\"<\/span>;\r\n}\r\n<\/code><\/pre>\n
          \n
        1. substitute<\/li>\n<\/ol>\n
          my<\/span> $str = \"Hello World\"<\/span>;\r\n$str =~ s\/Hello\/Hi\/<\/span>;\r\nprint<\/span> $str; # \u8f93\u51faHi World<\/span>\r\n<\/code><\/pre>\n
            \n
          1. \nfind()<\/li>\n<\/ol>\n
            my<\/span> $str = \"Hello World\"<\/span>;\r\nmy<\/span> $pos = index<\/span>($str, \"World\"<\/span>);\r\nprint<\/span> $pos; # \u8f93\u51fa6<\/span>\r\n<\/code><\/pre>\n
            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.<\/p>\n","protected":false},"excerpt":{"rendered":"
