这篇文章主要介绍了php遍历CSV类,实例分析了php针对csv文件的打开、读取及遍历的技巧,非常具有实用价值,需要的朋友可以参考下
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
 - ?>
 
希望本文所述对大家的php程序设计有所帮助。
