note 125719 added to function.str-getcsv

Sometimes the enclosure parameter of the str_getcsv function doesn't work, so I wrote a function that is equivalent to the function <?php /** * @param string $input * @param string $delimiter * @param string $enclosure * @param string $escape * @return array * @author TXX * @date 2021/1/25 15:03 */ function my_str_getcsv($input, $delimiter = ',', $enclosure = '"', $escape = '\\') { $output = array(); if (empty($input) || !is_string($input)) { return $output; } if (preg_match("/". $escape . $enclosure ."/", $input)) { while ($strlen = strlen($input)) { $pos_delimiter = strpos($input, $delimiter); //分隔符出现位置 $pos_enclosure_start = strpos($input, $enclosure); //封闭符-开始出现位置 //有封闭符并封闭符在分隔符之前 if (is_int($pos_delimiter) && is_int($pos_enclosure_start) && $pos_enclosure_start < $pos_delimiter) { $pos_enclosure_start += 1; $enclosed_str = substr($input, $pos_enclosure_start); //封闭字符串-开始 $pos_enclosure_end = strpos($enclosed_str, $enclosure); //封闭符-结尾封闭字符串-开始中出现位置 $pos_enclosure_end += $pos_enclosure_start; //封闭符-结尾在原始数据中出现位置 if ($pos_enclosure_end < $pos_delimiter) { //封闭符-结束在分隔符之前,无需进行封闭 $output[] = substr($input, 0, $pos_delimiter); $offset = $pos_delimiter + 1; } else { //封闭符-结束在分隔符之后,需要封闭 $pos_enclosure_end += 1; $before_enclosed_str = substr($input, 0, $pos_enclosure_end); $enclosed_str = substr($input, $pos_enclosure_end); //封闭字符串之后的字符串 $enclosed_arr = my_str_getcsv($enclosed_str, $delimiter, $enclosure); //将封闭之后的字符串执行自身 $enclosed_arr[0] = $before_enclosed_str . $enclosed_arr[0]; $output = array_merge($output, $enclosed_arr); $offset = strlen($input); //光标移至结尾 } } else { //无封闭 if (!is_int($pos_delimiter)) { //无分隔符,直接将字符串加入输出数组 $output[] = $input; //光标移至结尾 $offset = strlen($input); } else if ($input == $delimiter) { //如果字符串只剩下分隔符,需保存'','' $output = array_merge($output, ['','']); $offset = $pos_delimiter+1; //光标移至分隔符后一位 } else { $output[] = substr($input, 0, $pos_delimiter); //将分割符之前的数据 $offset = $pos_delimiter+1; //光标移至分隔符后一位 } } //将字符串更新至光标位置 $input = substr($input,$offset); } } else { //字符串中不存在封闭符,直接通过分隔符分割 $input = preg_split("/". $escape . $delimiter ."/", $input); if (is_array($input)) { $output = $input; } } return $output; } ?> ---- Server IP: 45.112.84.4 Probable Submitter: 45.91.159.166 (proxied: 119.122.115.58) ---- Manual Page -- http://php.net/manual/en/function.str-getcsv.php Edit -- https://master.php.net/note/edit/125719 Del: integrated -- https://master.php.net/note/delete/125719/integrated Del: useless -- https://master.php.net/note/delete/125719/useless Del: bad code -- https://master.php.net/note/delete/125719/bad+code Del: spam -- https://master.php.net/note/delete/125719/spam Del: non-english -- https://master.php.net/note/delete/125719/non-english Del: in docs -- https://master.php.net/note/delete/125719/in+docs Del: other reasons-- https://master.php.net/note/delete/125719 Reject -- https://master.php.net/note/reject/125719 Search -- https://master.php.net/manage/user-notes.php
