Call to undefined function readline()?

I am integrating Dropbox into my PHP based website. When i try to run the following code. i got this Fatal error: Call to undefined function readline() on the last line.

require_once "dropbox-sdk/Dropbox/autoload.php";
use \Dropbox as dbx;
$appInfo = dbx\AppInfo::loadFromJsonFile("app-info.json");

echo "<pre>";
print_r($appInfo);
echo "</pre>";

$webAuth = new dbx\WebAuthNoRedirect($appInfo, "PHP-Example/1.0");

echo "<pre>";
print_r($webAuth);
echo "</pre>";

$authorizeUrl = $webAuth->start();
echo "1. Go to: " . $authorizeUrl . "\n<br>";
echo "2. Click \"Allow\" (you might have to log in first).\n<br>";
echo "3. Copy the authorization code.\n<br>";
$authCode = \trim(\readline("Enter the authorization code here: "));

I have come through different forum where people said it will work in Command line , But I don't understand how? Any idea ?

readline() is for running on the command line not via the web browser.

To check you have it installed on your server, type:

php -i | grep Configure

Probably, you have not installed it and you should compile it yourself or ask your hosting admin to if they allow this.

Or just use this to simulate it

if(!function_exists("readline")) {
    function readline($prompt = null){
        if($prompt){
            echo $prompt;
        }
        $fp = fopen("php://stdin","r");
        $line = rtrim(fgets($fp, 1024));
        return $line;
    }
}

Just had this issue on Ubuntu.

Found this answer: https://askubuntu.com/a/264329/166

The solution in this scenario was to install the package php5-readline.
