php traverses CSV class instances, php traverses csv instances

The examples in this article describe php traversing CSV classes. Share it with everyone for your reference. The details are as follows:

<&#63;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
