[英]Issue with fopen and fwrite PHP
I'm having issues writing to the file VarLog.txt, It's not read only (In properties), I'm trying to write the Variable or SQL Query as a string in the logs file that I created, I also wrote a check to see if VarLog exists, and if it doesn't, make it. 我在写入文件VarLog.txt时遇到问题,它不是只读的(在属性中),我正在尝试将变量或SQL查询作为字符串写入我创建的日志文件中,我还写了一个检查查看VarLog是否存在,如果不存在,则进行创建。 Here's the Code 这是代码
if (!file_exists( "VarLog.txt")) {
$fh = fopen("VarLog.txt", 'w') or die("can't open file");
fclose($fh);
}
function anti_injection($sql) {
$fp = fopen("VarLog.txt", "a+");
$sql = preg_replace(sql_regcase("/(from|select|insert|delete|where|drop table|show tables|#|\*|--|\\\\)/"),"",$sql);
$sql = trim($sql);
$sql = strip_tags($sql);
$sql = addslashes($sql);
fwrite($fp, "SQL Query/String: $sql");
fclose($fp);
return $sql;
}
An Example of a $_POST variable $ _POST变量的示例
anti_injection($_POST['email']);
The code itself doesn't present any errors, other than the first check if the file exists and creating it is redundant. 除了首先检查文件是否存在并创建冗余文件外,代码本身不会出现任何错误。
getcwd()
to find out what that path is, and check there). 现在您的路径不是绝对路径,因此将相对于当前工作目录的内容写入文件(使用getcwd()
找出该路径是什么,然后在此处检查)。
