The issue of garbled characters when reading databases in PHP is usually caused by a mismatch between the character sets of the database and the PHP code. Here are some solutions:<\/p>\n

    \n
  1. Check the character set of the database and tables: Make sure the character set of the database and tables is set correctly, common character sets include UTF-8, GBK, etc. You can confirm by checking the character set in the database.<\/li>\n
  2. Set the character encoding for PHP code: Use the mysqli_set_charset() function in PHP code to ensure it matches the character encoding of the database.<\/li>\n<\/ol>\n
    \/\/ \u8bbe\u7f6e\u5b57\u7b26\u96c6\u4e3aUTF-8<\/span>\r\nmysqli_set_charset<\/span>($conn<\/span>, 'utf8'<\/span>);\r\n<\/code><\/pre>\n
      \n
    1. establish a connection with MySQL database<\/li>\n<\/ol>\n
      \/\/ \u8fde\u63a5\u6570\u636e\u5e93\u5e76\u8bbe\u7f6e\u5b57\u7b26\u96c6\u4e3aUTF-8<\/span>\r\n$conn<\/span> = mysqli_connect<\/span>($host<\/span>, $username<\/span>, $password<\/span>, $database<\/span>);\r\nmysqli_set_charset<\/span>($conn<\/span>, 'utf8'<\/span>);\r\n<\/code><\/pre>\n
        \n
      1. Change the structure of the table<\/li>\n<\/ol>\n
        ALTER<\/span> TABLE<\/span> table_name CONVERT<\/span> TO<\/span> CHARACTER<\/span> SET<\/span> utf8;\r\n<\/code><\/pre>\n
          \n
        1. Convert the encoding using mb_convert_encoding().<\/li>\n<\/ol>\n
          $data<\/span> = mb_convert_encoding<\/span>($data<\/span>, 'UTF-8'<\/span>, '\u539f\u5b57\u7b26\u96c6'<\/span>);\r\n<\/code><\/pre>\n
            \n
          1. HTML element to provide metadata about the webpage.<\/li>\n<\/ol>\n
            <meta<\/span> charset<\/span>=\"UTF-8\"<\/span>><\/span>\r\n<\/code><\/pre>\n
            By implementing the above methods, the issue of PHP reading database gibberish can be resolved. Choose the appropriate method based on the specific situation.<\/p>\n","protected":false},"excerpt":{"rendered":"
