Php + regExp, how?

Question

PHP

We have a simple example (in php):

$text='\\';
preg_match_all('/\\\\/',$text,$item);
print_r($item);

At the output we get:

Array
(
    [0] => Array
        (
            [0] => \
        )

)

The question is how to get 2 slashes instead of one? It is necessary not to adapt to the desired string, but somehow disable the escaping of the slash in php.

Answer 1

Or is it better to use var_dump instead of print_r?

Answer 2

How are you going to get 2 slashes if there is only one in the input?
This is how you get two:

$text='\\\\';
preg_match_all('/\\\\+/',$text,$item);

Answer 3

Do an
echo $text;

Answer 4

I came up with only a variant with preg_quote:

preg_match_all('/'.preg_quote('\\\\','/').'/',preg_quote($text,'/'),$item);

or, if you need slashes separately, then
preg_match_all('/\\\\/',preg_quote($text,'/'),$item);
