php读取csv数据保存到数组代码
csv是常用的excel格式的替代品,很多时候我们导出数据是都会导成csv格式的,这样和excel没什么区别,下面的程序是要读取csv数据保存到数组我们要对数据进行操作,所以保存到数据,代码如下:
- $info=csvtoarray::open('teste.csv');
-
-
-
- foreach ($info as $c)
- {
- echo '学号:'.$c[0];
- echo '姓名:'.$c[1];
- echo '年龄:'.$c[2];
- echo '身高:'.$c[3].'<br>';
- }
-
-
- final class csvtoarray{
-
-
-
-
-
-
-
-
- public static function open($file, $delimiter = ';'){
- return self::ordenamultiarray(self::csvarray($file, $delimiter), 1);
- }
-
- private function csvarray($file, $delimiter)
- {
- $result = array();
- $size = filesize($file) + 1;
- $file = fopen($file, 'r');
- $keys = fgetcsv($file, $size, $delimiter);
- fseek($file,0);
- while ($row = fgetcsv($file, $size, $delimiter))
- {
- for($i = 0; $i < count($row); $i++)
- {
- if(array_key_exists($i, $keys))
- {
- $row[$keys[$i]] = $row[$i];
- }
- }
- print_r($row);
- $result[] = $row;
- }
-
- fclose($file);
-
- return $result;
- }
- private function ordenamultiarray($multiarray, $secondindex)
- {
- while (list($firstindex, ) = each($multiarray))
- $indexmap[$firstindex] = $multiarray[$firstindex][$secondindex];
- asort($indexmap);
- while (list($firstindex, ) = each($indexmap))
- if (is_numeric($firstindex))
- $sortedarray[] = $multiarray[$firstindex];
- else $sortedarray[$firstindex] = $multiarray[$firstindex];
- return $sortedarray;
- }
- }
