If I assign values to array like this:
$foo[0] = 2;
$foo[1] = 3;
print_r($foo);
I get:
Array
(
[0] => 2
[1] => 3
)
But if I do:
$foo[1] = 3;
$foo[0] = 2 ;
print_r($foo);
I get:
Array
(
[1] => 3
[0] => 2
)
As you can see first goes array with index 1 and it confuses me, is it possible to make that it would start from 0
If you interested, I assign value to array with index 1 because I need to use that value for calculating array with index 0
try to use ksort();. It sorts your keys ascending
<?php
$foo[1] = 3;
$foo[0] = 2 ;
ksort($foo);
print_r($foo);
results in
Array (
[0] => 2
[1] => 3
)
ksort() does would be helpful.
Returns TRUE on success or FALSE on failure. that line prints that returnvalue (probably true), and not the sorted array
print_r on the array. The argument is passed as reference.Try ksort()
The reason it is like this in PHP, is because arrays are a bit different from arrays in other languages. Arrays in PHP are somewhat similar to HashMaps in Java and Dictionaries in C#, although still a bit different.
print_ris the final use you have for that$foo. Could it be that this is a presentation issue only? If you access$foo[0]you'll still get the same result, sorted or not. You could ofcourse use theksort()option provided in the answers, but first consider if you need it.
