Backslashes from textbox forms are returned as double-backslashes. Why?

[wylbur37]

When using a form with an input textbox such as the following ...

<input type="text" name="field1" size=30>

I discovered that when a backslash (\) is typed into the textbox,
when I later check the value (in $field1), I get *two* backslashes.
For example, If I type ...

c:\abc\xyz

the $field1 variable will then have a value of ...

c:\\abc\\xyz

Why does this happen?

Read These From Manual:

http://php.net/manual/en/security.magicquotes.php

When on, all ' (single-quote), " (double quote), \ (backslash) and NULL
characters are escaped with a backslash automatically.

http://php.net/manual/en/function.stripslashes.php

Returns a string with backslashes stripped off. (\' becomes ' and so on.)
Double backslashes (\\) are made into a single backslash (\).

Obviously a \ is an escape character in literal strings. E.g. \n \r \t
and so on.

So something somewhere is escaping the \ in the path name otherwise
your path name may not come across correctly.

How are you "checking" $field1 and are you passing it as a query
string? You need to be more specific.
