Shortest Code to Translate a PHP array NOTE: This question was migrated from https://stackoverflow.com/q/27134588/1442685

PHP QUESTION

Almost purely out of curiousity, how can I take an array like this:

array( 'fruit' =&gt; 'banana', 'drink' =&gt; 'milk')


And convert it to an array like this:

array( 'fruit=banana', 'drink=milk')


Requirements


Cannot use anonymous functions
If needed, can only use array_* functions that accept callable if that callable is native to PHP
Must be a one-liner solution




This is not for a class. I'm curious to see how clever one can be with array functions. Given the requirements, is it possible?
explode('&amp;',http_build_query($a))
