Thanks for trying out code.he.net Beta.

Please run them as a single line(see below):

php> $numbers=array(1,5,10); $fruits=array('apple','banana','watermelon'); $mixed = array_combine($numbers,$fruits); echo $mixed[10];

Let us know if the problem continues.

Yes, the exception was caused by the compiler compile each line, so that it can not understand $number and $fruits
