Question

I want to add a Hash key/value pair to an empty array.

Here is how I am trying to do it, however I am getting an error:

Parse error: syntax error, unexpected T_DOUBLE_ARROW

Here is my code:

$key = (string)$degree->f[0];
$value = (string)$degree->f[1];        
$SDP_ID2CohortMap[] = ( $key => $value );

Answer 1

$SDP_ID2CohortMap = array( $key => $value );
$SDP_ID2CohortMap[$key] = $value;

But not both at the same time.
