PHP：填充一个值高达某个索引的数组？ [关闭]

Question

Is there a way to fill up an array with values? I have an array with 5 elements and I want to add the string "filler" to the end until 10 elements are filled.

I tried to find a suitable PHP function, but failed so far. Is there a function at all, or do I have to use a loop?

Thanks

The built-in function array_pad serves exactly this purpose.

$padded_array = array_pad($source_array,10,"filler");
