I have a problem with the special character \ (backslash) in php. If I have the following code:

$f="aboca.png";
$ficheros[]=array("title" => $f, "description" => $f, "image" => "select\".$f");
pirnt_r($ficheros);

The result is:

Array ( [0] => Array ( [title] => aboca.png [description] => aboca.png [image] => select".aboca.png )

and I need the result to be as follows:

Array ( [0] => Array ( [title] => aboca.png [description] => aboca.png [image] => select\aboca.png )

I already know that \ is a special character and I've tried several combinations but there's no way.

This should work (\\):

$f="aboca.png";
$ficheros[]=array("title" => $f, "description" => $f, "image" => "select\".$f");
pirnt_r($ficheros);

There is also the PHP constant DIRECTORY_SEPARATOR .

$f = "aboca.png";
$ficheros = array("title" => $f, "description" => $f, "image" => "select" . "\" . $f );
print_r($ficheros);

I think it's because you have left over quotes at the end:

 "select\".$f");

after the $ f

In PHP you can define the literals in different ways if you include it with double comma " PHP takes into account the special characters \ n \ t \ etc etc ...

Better to use ', your code with single quotes:

$f='aboca.png';
$ficheros[]=array('title' => $f, 'description' => $f, 'image' => 'select\'.$f);
pirnt_r($ficheros);

If you define literals using double comma, you should use \

$f="aboca.png";
$ficheros[]=array("title" => $f, "description" => $f, "image" => "select\$f");
pirnt_r($ficheros);

You have several ways to solve it, taking into account that the main idea is to escape the character.

Escaping the '\' backSlash
If a string is delimited with double quotes ("), PHP will interpret more escape sequences as special characters: more info

solution : '\\' backslash

$ficheros = array("title" => $f, "description" => $f, "image" => "select\".$f);

It can also look like this:

$ficheros = array("title" => $f, "description" => $f, "image" => "select\.$f");

Note: If you use double quotes (") you can put the variable php in without any problem.
