想了解php遍历CSV类实例的相关内容吗，不吃皮蛋在本文为您仔细讲解php遍历CSV类的相关知识和一些Code实例，欢迎阅读和指正，我们先划重点：php,遍历,CSV,类，下面大家一起来学习吧。

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：

<?php
class 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
?>
