Hi,

Is there a function or script that can make sure a string can be stored with serialize?
Its got html tags and alsort in it...

PHP Code:

$store = serialize(array(

   'content' => $string

)); 

I know this is not the best way to store stuff... this is some super old code

Thanks,
Lex

base64_encode() is the first and most secure thing that comes to mind.

Ah thank you,
Is there a way to see if the value needs decoding? Forgot about the existing data :S

Try this:


base64_decode — Decodes data encoded with MIME base64
PHP: base64_decode - Manual

Usage:
string base64_decode ( string $data [, bool $strict= false ] )

data - The encoded data.
strict - Returns FALSE if input contains character from outside the base64 alphabet.

PHP Code:

$str = 'VGhpcyBpcyBhbiBlbmNvZGVkIHN0cmluZw==';
echo base64_decode($str);
?> 

You might also use this regular expression:

^[a-zA-Z0-9/+]*={0,2}$

Which will also detect the usage of = or == at the end of the string (and only end). A function geared specifically toward this:

PHP Code:

<?php

function is_base64_encoded()
    {
        if (preg_match('%^[a-zA-Z0-9/+]*={0,2}$%', $data)) {
            return TRUE;
        } else {
            return FALSE;
        }
    };

is_base64_encoded("iash21iawhdj98UH3"); // true
is_base64_encoded("#iu3498r"); // false
is_base64_encoded("asiudfh9w=8uihf"); // false
is_base64_encoded("a398UIhnj43f/1!+sadfh3w84hduihhjw=="); // true

?>

It's not mine, but I'll happily take credit for it.
