String offset cast occurred

[SnakeME]

I'm currently running PHP 5.4.16 and get the following error when i use the getShortenedURLFromID function:

Severity: Notice
Message: String offset cast occurred

Line:
$out = $base[fmod($integer, $length)] . $out;

[SnakeME]

Solution:

Convert $base into an array with the following format:

$base = array('0' => '0', '1' => '1', '2' => '2', '3' => '3', '4' => '4', '5' => '5', '6' => '6', '7' => '7', '8' => '8', '9' => '9', '10' => 'a', '11' => 'b' etc.

If i find time i'll open an pull request

You could use str_split():

function getShortenedURLFromID ($integer, $base = ALLOWED_CHARS)
{
    $length = strlen($base);
    $base = str_split($base);
    $out = '';
    while($integer > $length - 1)
    {
        $out = $base[fmod($integer, $length)] . $out;
        $integer = floor( $integer / $length );
    }
    return $base[$integer] . $out;
}

Thanks, @osthafen !

@RationalEar how to fix code sir?

@kudataz, in the getShortenedURLFromID() function, just convert the string variable $base to an array by adding this line before the while statement:

$base = str_split($base);
