Unique variables inside foreach()
Trying to create a variable with unique name for each $item
.
To prevent error "Only variables can 开发者_Go百科be passed by reference".
If there are 5 items in array $items
, we should get 5 unique variables:
$item_name_1;
$item_name_2;
$item_name_3;
$item_name_4;
$item_name_5;
All of them should be empty.
What is a true solution for this?
You can dynamically create variable names doing the following:
$item_name_{$count} = $whatever;
I must warn you though, this is absolutely bad style and I've never seen a good reason to use this. In almost every use case an array would be the better solution.
Well, I guess that you can use $item_name_{$count} = "lorem ipsum"; for it
... But won't be better to use an array?
I'm not sure I understand what you want to do, so this may be completely wrong. Anyway, if what you want is an array with empty values you can use this code:
<?php
$arr = array_fill(0, 3, '');
var_export($arr) // array ( 0 => '', 1 => '', 2 => '', 3 => '', )
?>
See array_fill for more information.
If this is the wrong answer, please clarify what you mean. I may be able to help you.
