php遍历CSV类实例

本文实例讲述了php遍历CSV类。分享给大家供大家参考。具体如下：

<?phpclass CSVIterator implements Iterator{ const ROW_SIZE = 4096;private $filePointer;private $currentElement;private $rowCounter;private $delimiter;public function __construct（ $file, $delimiter = "," ）{$this->filePointer = fopen（ $file, "r" ）;$this->delimiter= $delimiter;}public function rewind（）{$this->rowCounter = 0;rewind（ $this->filePointer ）;}public function current（）{$this->currentElement = fgetcsv（$this->filePointer,self::ROW_SIZE,$this->delimiter）;$this->rowCounter++;return $this->currentElement;}public function key（）{return $this->rowCounter;}public function next（）{return ！feof（ $this->filePointer ）;}public function valid（）{if（ ！$this->next（） ）{fclose（ $this->filePointer ）;return FALSE;}return TRUE;}} // end class?>

希望本文所述对大家的php程序设计有所帮助。
