<?php
$tab=array(
"January"=>array(),
"February"=>array(),
"March"=>array(),
"April"=>array(),
"May"=>array(),
"June"=>array()
);
foreach($tab as $month=>$number)
for($i=0;$i<6;$i++)
array_push($number,rand(10,20));
print_r($tab);
?>
I'm trying to push multiple numbers into an array which is inside an array where the keys are the names of months. print_r displays empty arrays. I don't know what I did wrong.

“I don't know what I did wrong.” - you did not read the manual forforeachattentively enough, because it explains what you need to do to manipulate the array you are looping over inside the loop.

In his eloquent comment, misorude meant to refer you to this paragraph of the foreach documentation:
In order to be able to directly modify array elements within the loop precede
$value with &. In that case the value will be assigned by
reference.
So, you could change your foreach to
foreach ($tab as &$number)
(since you don't need the key in your loop, you can omit $month=>).
