note 99108 modified in function.curl-setopt by danbrown

Be careful when setting the CURLOPT_POSTFIELDS setting using an array. The array used to set the POST fields must only contain scalar values. Multidimentional arrays or objects lacking a __toString implementation will cause Curl to error. If there is a need to send non-scalar values using a POST request, consider serializing them before transmission. <?php $ch = curl_init('http://host.example.com'); // Data to post $multiDimensional = array( 'name' = 'foo', 'data' = array(1,2,3,4), 'value' = 'bar' ); // Will error curl_setopt($ch, CURLOPT_POSTFIELDS, $multiDimensional); // Data to post $postData = array( 'name' = 'foo', 'data' = serialize(array(1,2,3,4)), 'value' = 'bar' ); // Will not error curl_setopt($ch, CURLOPT_POSTFIELDS, $postData); ?> --was-- Be careful when setting the CURLOPT_POSTFIELDS setting using an array.
