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：
<?php
classCSVIteratorimplementsIterator
{
constROW_SIZE=4096;
private$filePointer;
private$currentElement;
private$rowCounter;
private$delimiter;
publicfunction__construct($file,$delimiter=',')
{
$this->filePointer=fopen($file,'r');
$this->delimiter=$delimiter;
}
publicfunctionrewind()
{
$this->rowCounter=0;
rewind($this->filePointer);
}
publicfunctioncurrent()
{
$this->currentElement=fgetcsv($this->filePointer,self::ROW_SIZE,$this->delimiter);
$this->rowCounter++;
return$this->currentElement;
}
publicfunctionkey()
{
return$this->rowCounter;
}
publicfunctionnext()
{
return!feof($this->filePointer);
}
publicfunctionvalid()
{
if(!$this->next())
{
fclose($this->filePointer);
returnFALSE;
}
returnTRUE;
}
}//endclass
?>
希望本文所述对大家的php程序设计有所帮助。
