PHP PDO Safe string

Posted on 2016-10-04

Im trying to backup my SQL databases (as cant connect remotly to do a backup, and cant use mysqldump), and I have the values from the database, but I want to store them safely in a text file, which means escaping characters such as "\n".

My initial ideal was to use str_replace, but I could be here for ages doing it. Then I thought about converting the string to hex codes and using that, but it seems a bit messy.

What I really want to do is do something like :-
<?php

$strOutput = <<<EOD
This is a 
test with a % character.
EOD;

echo mysqli::real_escape_string($strOutput);

?>

Open in new window


But all I get is:-
E_ERROR : type 1 -- Non-static method mysqli::real_escape_string() cannot be called statically -- at line 8

Any suggestions?

Instantiate a MySQLi object, then call the method with non-static OOP notation.  Something like this:

$x = new MySQLi( ... );
$y = $x->real_escape_string($strOutput);
echo $y;

Open in new window

Non-static methods require an object instance.
