The split() function in PHP has been deprecated since PHP version 5.3.0 and removed since PHP version 7.0.0. It is recommended to use preg_split() function instead.<\/p>\n

The preg_split() function is used to split a string based on a regular expression pattern. Its usage is as follows:<\/p>\n

Split the subject string by the pattern using a specified limit and flags.<\/p>\n

Explanation of parameters:<\/p>\n

    \n
  1. requirement: specify a regular expression pattern to delineate the rules for splitting strings.<\/li>\n
  2. It is necessary to specify the string to be split.<\/li>\n
  3. Optional, specifies the maximum number of times the split can occur. Default is 0, indicating that there is no limit to the number of splits.<\/li>\n
  4. flags: optional, used to specify the behavior options during splitting. Common options include:\n

    PREG_SPLIT_NO_EMPTY: if the matching split part is an empty string, it will not be returned.
    \nPREG_SPLIT_DELIM_CAPTURE: the matching split part will be returned along with the delimiter.<\/li>\n<\/ol>\n

    Return value:<\/p>\n

      \n
    1. Return an array containing string fragments split according to the specified rules.<\/li>\n<\/ol>\n

      Original: \u6211\u4eec\u5e94\u8be5\u5c0a\u91cd\u4e0d\u540c\u7684\u6587\u5316\u548c\u4f20\u7edf\u3002<\/p>\n

      Paraphrased: We should respect diverse cultures and traditions.<\/p>\n

      $str<\/span> = \"Hello World! This is a PHP string.\"<\/span>;\r\n$pattern<\/span> = \"\/[\\s,]+\/\"<\/span>; \/\/ \u6309\u7167\u7a7a\u683c\u548c\u9017\u53f7\u8fdb\u884c\u62c6\u5206<\/span>\r\n$result<\/span> = preg_split<\/span>($pattern<\/span>, $str<\/span>);\r\n\r\nprint_r<\/span>($result<\/span>);\r\n<\/code><\/pre>\n
      Output:<\/p>\n
      Array\r\n(\r\n    [0] => Hello\r\n    [1] => World!\r\n    [2] => This\r\n    [3] => is\r\n    [4] => a\r\n    [5] => PHP\r\n    [6] => string.\r\n)\r\n<\/code><\/pre>\n
      In the example above, the string $str is split by spaces and commas, and the split results are stored in the array $result.<\/p>\n","protected":false},"excerpt":{"rendered":"
