I have no idea what I'm doing wrong...
<?php
class Render {
public static function displayDimensions($size)
{
return implode("", $size[0]) . "". "X" . "" . implode("", $size[1]);
}
//return displayDimensions();
}
?>

return implode("", $size[0]) . "". "X" . "" . implode("", $size[1]);
// 1. You don't need to use implode
return $size[0] . "". "X" . "" . $size[1];
//2 You need to put a space in your "" so it will be " "
return $size[0] . " ". "X" . " " . $size[1];
//3 The "X" needs to be "x"
return $size[0] . " ". "x" . " " . $size[1];
// Cleaned
return $size[0] . " x " . $size[1];
Answer:
<?php
class Render {
public static function displayDimensions($size)
{
return $size[0] . " x " . $size[1];
}
}
?>
The Error when you preview is:
PHP Warning: implode(): Invalid arguments passed in index.php on line 6 PHP Warning: implode(): Invalid arguments passed in index.php on line 6
php.net manual says: implode ( string $glue , array $pieces ) : string
/*
It is asking for glue and an array
but you are passing it just one item out of your array when you designate [0] or [1]
*/
implode("", $size[0]);
//to implode you would pass it like this
implode("", $size);
/*
But you would get 1214 if the challenge was set up correctly.
Since it wasn't; you will get 111222.
