你可以将键附加到数组变量，如python字典？

Question

Ok so I have this function that eventually returns and array return array($offset , $currentpage , $totalpages , $rowsperpage);

I would like to reference this array with keywords like $variablecontainingarray['offset] rather than $variablecontainingarray[0]

is this possible? I know something similar existed in python. >>> d = {'key':'value'}

i'd like to have a variable store the output of the array from the function and give a keyword to the values for easier reference.

In php you can use arrays in the same way. http://php.net/manual/en/function.array.php

So you could do:

return array(
    'offset'      => $offset,
    'currentpage' => $currentpage,
    'totalpages'  => $totalpages,
    'rowsperpage' => $rowsperpage,
);

Furthermore you could use compact to keep it all on one line:

return compact('offset' , 'currentpage' , 'totalpages' , 'rowsperpage');

You can find more information on compact here: http://php.net/manual/en/function.compact.php

Hope this helps!
