if(file_exists("temp.txt")) unlink("temp.txt");
$query = "select * into outfile 'temp.txt' FIELDS TERMINATED BY ',' from tbl_user ";
$myfile=file("temp.txt");
for($index=0;$index {
print($myfile[$index]);
}
运行它之后为什么会出现这样的提示：

Warning: file("temp.txt") - No such file or directory in 456.php on line 3
