sizeof(): Parameter must be an array or an object that implements Countable

[Marcelofj]

Hi, how can I Solve this?

private function _convertToArray($param)
    {
        $ret = array();
        foreach ($param as $k => $v) {
            if ($v instanceof PayPalModel) {
                $ret[$k] = $v->toArray();
            } elseif (sizeof($v) <= 0 && is_array($v)) {  // this code error line
                $ret[$k] = array();
            } elseif (is_array($v)) {
                $ret[$k] = $this->_convertToArray($v);
            } else {
                $ret[$k] = $v;
            }
        }
        // If the array is empty, which means an empty object,
        // we need to convert array to StdClass object to properly
        // represent JSON String
        if (sizeof($ret) <= 0) {
            $ret = new PayPalModel();
        }
        return $ret;
    }

Thanks.

I also keep getting this same error. Running the example provided in the readme generates this exact error.

I found this in paypal/PayPal-PHP-SDK#1014
You need to change:

} elseif (sizeof($v) <= 0 && is_array($v) ) {
to
} elseif (is_array($v) && sizeof($v) <= 0) {

For reference, in my case it was in /includes/libs/PayPal-PHP-SDK/paypal/rest-api-sdk-php/lib/PayPal/Common/PayPalModel.php
