[Solved] Delete first array php

by


The only reason why you would get such an output is because you print_r inside the loop.

I believe you have something like:

$aa = [47, 51];

foreach($aa as $a){
    $b[] = $a;
    print_r($b);
}

/*Output:
Array
(
    [0] => 47
)
Array
(
    [0] => 47
    [1] => 51
)*/

But instead you should have done this:

$aa = [47, 51];

foreach($aa as $a){
    $b[] = $a;
}
print_r($b);

/*Output:
Array
(
    [0] => 47
    [1] => 51
)

Here you can see the difference.

First two outputs are from inside the loop, the last is after the loop.

I.e. your code is correct but the output is placed wrong and therefore confusing you to believe there is two items with key 0 and value 47.
