復(fù)制代碼 代碼如下:

<?php
$filename = "html/cache.txt";
$contents = "我是張斌";
if(is_writable($filename)){
if(($handle = fopen($filename,"a") )== false){
echo "寫入文件 $filename 失敗";
exit();
}
if(fwrite($handle,$contents) == false){
echo "寫入文件$filename失敗";
exit();
}
echo "寫入文件 $filename 成功";

fclose($handle);
}else{
echo "文件$filename不可寫入";
}
?>
