复制代码 代码如下:

<?php
$filename=dirname(__FILE__).\"/readfrom.txt\";
$ofilename=dirname(__FILE__).\"/writeto.txt\";

if(!file_exists($filename)){
echo $filename.\" not found!\";
exit;
}

$fp=fopen($filename,\"r\");
$fo = fopen($ofilename,\"w\");

while(!feof($fp)){

$record=fgets($fp);

if($record!=NULL){
$record_arr=explode(\"\\t\", $record);

fwrite($fo,$record,strlen($col));
}


}
fclose($fo);
fclose($fp);

?>
