La funzione restituisce una stringa con il carattere backslash anteposto ai caratteri
|
|
che richiedono l'escape. Questi caratteri sono:
|
|
<simplelist>
|
|
<member>virgoletta singola (<literal>'</literal>)</member>
|
|
<member>doppia virgoletta (<literal>"</literal>)</member>
|
|
<member>backslash (<literal>\</literal>)</member>
|
|
<member>NUL (il byte NUL)</member>
|
|
</simplelist>
|
|
</para>
|
|
<para>
|
|
Un caso d'uso di <function>addslashes</function> è fare l'escape dei suddetti
|
|
caratteri in una stringa che deve essere eseguita come script da PHP:
|
|
<informalexample>
|
|
<programlisting role="php">
|
|
<![CDATA[
|
|
<?php
|
|
$str = "O'Reilly?";
|
|
eval("echo '" . addslashes($str) . "';");
|
|
?>
|
|
]]>
|
|
</programlisting>
|
|
</informalexample>
|
|
</para>
|
|
<para>
|
|
A volte <function>addslashes</function> è erroneamente utilizzato per provare a prevenire
|
|
<link linkend="security.database.sql-injection">SQL Injection</link>. Invece,
|
|
dovrebbero essere usate funzioni di escape specifiche per il database e/o prepared statement.
