I'm confused about an error I am getting stating Array to string conversion

The reason I'm confused is I'm trying to do exactly that, convert an array to a string, using implode which according to the manual should allow me to convert my array into a string. So why am I getting an error?

var $matches is an array. $error_c is the var I want to store the string.

print_r($matches); // prints the array correctly
$error_c = implode(',', $matches);
echo $error_c;

Outputs simply array and gives:

Notice: Array to string conversion in ...

The manual states that implode — Join array elements with a string so why do I get an error when I try to do it?

Edit: this is the output I get from $matches

Array ( [0] => Array ( [0] => C [1] => E [2] => R [3] => R [4] => O [5] => R [6] => C [7] => O [8] => N [9] => T [10] => A [11] => C [12] => T [13] => S [14] => U [15] => P [16] => P [17] => R [18] => E [19] => S [20] => S [21] => E [22] => D ) )

the element of your array should be string or have __toString capability –  George Garchagudashvili Sep 19 '14 at 8:43

You have an array of arrays... Try this:

$error_c = implode(',', $matches[0]);

Do that:

print_r($matches); // prints the array correctly
$error_c = implode(',', $matches[0]);
echo $error_c;

$error_c = implode(',', $matches[0]);
echo $error_c;

because your array contains arrays inside
