Be careful if you choose to escape characters 0, a, b, f, n, r,

t and v. They will be converted to \0, \a, \b, \f, \n, \r, \t

In PHP \0 (NULL), \r (carriage return), \n (newline) and \t (tab)

Returns a string with backslashes before characters that need

to be quoted in database queries etc. These characters are

single quote (<literal>'</literal>), double quote

(<literal>"</literal>), backslash (<literal>\</literal>)
|

and NUL (the &null; byte).
|

</para>
|

<para>
|
||||
An example use of <function>addslashes</function> is when you're
|
||||
entering data into a database. For example, to insert the name
|
||||
<literal>O'reilly</literal> into a database, you will need to escape
|
||||
it. Most databases do this with a <literal>\</literal> which would
|
||||
mean <literal>O\'reilly</literal>. This would only be to get the data
|
||||
into the database, the extra <literal>\</literal> will not be inserted.
|
||||
Having the PHP directive <link linkend="ini.magic-quotes-sybase">
|
||||
magic_quotes_sybase</link> set to <literal>on</literal> will mean
|

<literal>'</literal> is instead escaped with another

<literal>'</literal>.

<para>
|

The PHP directive <link linkend="ini.magic-quotes-gpc">

magic_quotes_gpc</link> is <literal>on</literal> by default, and it
|

essentially runs <function>addslashes</function> on all GET, POST,
|

and COOKIE data. Do not use <function>addslashes</function> on
|
||||
strings that have already been escaped with
|
||||
<link linkend="ini.magic-quotes-gpc">magic_quotes_gpc</link> as you'll
|
||||
then do double escaping. The function
|

<function>get_magic_quotes_gpc</function> may come in handy for

checking this.

|

Some operating systems support more than one type of encryption. In
|
||||
fact, sometimes the standard DES-based encryption is replaced by an
|
||||
MD5-based encryption algorithm. The encryption type is triggered by the
|
||||
salt argument. At install time, PHP determines the capabilities of the
|
||||
crypt function and will accept salts for other encryption types. If no
|
||||
salt is provided, PHP will auto-generate a standard two character salt by
|
||||
default, unless the default encryption type on the system is MD5, in
|
||||
which case a random MD5-compatible salt is generated. PHP sets a
|
||||
constant named CRYPT_SALT_LENGTH which tells you whether a regular two
|
||||
character salt applies to your system or the longer twelve character salt
|
||||
is applicable.
|
||||
</simpara>
|
||||
<simpara>
|
||||
If you are using the supplied salt, you should be aware that the salt is
|
||||
generated once. If you are calling this function repeatedly, this may
|
||||
impact both appearance and security.

The standard DES-based encryption <function>crypt</function> returns the

salt as the first two characters of the output. It also only uses the

first eight characters of <parameter>str</parameter>, so longer strings
|

On systems where the crypt() function supports multiple
