problems with array_reverse

Question

I have a multi dimensional array, which is printed out. But it is printed in reverse order how I need. But when I try to use array_reverse() it outputs almost random values:

for($j=0; $j<count($positions);$j++){
    $temp[$j]=strlen($positions[$j]);
}
array_push($GLOBALS['lengths'],$temp);

and when I echo $lengths I get(as it should be, but in reverse order):

1 1
2 1

but when I use array_reverse($GLOBALS['lengths']) I get:

4 1
2 1

where might be the issue?

Thats the code that I use:

for($j=0; $j<count($positions);$j++){

    $temp[$j]=strlen($positions[$j]);
}
array_push($GLOBALS['lengths'],$temp);
$lengths=array_reverse($GLOBALS['lengths']);

Please show us the array declaration and what your goal is? Something like: this is the situation and this is my goal — Rizier123

Where is the code that outputs your array? What's the content of $positions? Is it an array of strings or an array of arrays? I noticed you are using strlen and not count. — André Laszlo

try array_reverse($GLOBALS['lengths'], true); to preserve keys it will give a good hint. — Victory

@Rizier123 codepaste.net/tx5c9m Firstly, I want to find the position of a given text in the string, and then to save that positions' length in the array $lengths — yamahamm

Try this:

//this will reverse the result output
for($j=count($positions); $j>0; $j--){
    array_push($GLOBALS['lengths'],strlen($positions[$j-1]));
}
$lengths=$GLOBALS['lengths'];
