Sort associative array












0















This has been asked before but the examples given have not worked for me.



I have an array with two keys



$miarray = array(

    array('factor' => $textof[1],    'valor' => $i1),

    array('factor' => $textof[2],    'valor' => $i2),

    array('factor' => $textof[3],    'valor' => $i3),

    array('factor' => $textof[4],    'valor' => $i4),

    array('factor' => $textof[5],    'valor' => $i5),

    array('factor' => $textof[6],    'valor' => $i6),

    array('factor' => $textof[7],    'valor' => $i7),

    array('factor' => $textof[8],    'valor' => $i8),

    array('factor' => $textof[9],    'valor' => $i9),

    array('factor' => $textof[10],    'valor' => $i10),

);


And if I go through the array I get the output in the original order



foreach ($miarray as $optionArray){ 

$pr .= "$optionArray[factor] - $optionArray[valor]<br>";

}


I need them to be sorted ascending according to the key 'valor' so i tried using usort



usort($miarray, 'sort_valor');


with the following function I found in the examples given.



function sort_valor($a, $b)

{

    $a = $a['valor'];

    $b = $b['valor'];



    if ($a == $b) return 0;

    return ($a < $b) ? -1 : 1;

}


but I get the following error




[20-Nov-2018 19:12:08 UTC] PHP Warning: usort() expects parameter 2
to be a valid callback, function 'sort_valor' not found or invalid
function name in xxxxxxxxxxx

    Can you post your full code? I can't reproduce your problem.

  • @FatemehNB PHP will hoist the comparator function. It shouldn't be an issue here.

    Is this code running within a class?

    You have sort_valor in your JavaScript code, not PHP.

    BTW, you can simplify it to just function sort_valor($a, $b) { return $a['valor'] - $b['valor']); }

    Can you post your full code? I can't reproduce your problem.

  • @FatemehNB PHP will hoist the comparator function. It shouldn't be an issue here.

    Is this code running within a class?

    You have sort_valor in your JavaScript code, not PHP.

    BTW, you can simplify it to just function sort_valor($a, $b) { return $a['valor'] - $b['valor']); }

This has been asked before but the examples given have not worked for me.



I have an array with two keys



$miarray = array(

    array('factor' => $textof[1],    'valor' => $i1),

    array('factor' => $textof[2],    'valor' => $i2),

    array('factor' => $textof[3],    'valor' => $i3),

    array('factor' => $textof[4],    'valor' => $i4),

    array('factor' => $textof[5],    'valor' => $i5),

    array('factor' => $textof[6],    'valor' => $i6),

    array('factor' => $textof[7],    'valor' => $i7),

    array('factor' => $textof[8],    'valor' => $i8),

    array('factor' => $textof[9],    'valor' => $i9),

    array('factor' => $textof[10],    'valor' => $i10),

);


And if I go through the array I get the output in the original order



foreach ($miarray as $optionArray){ 

$pr .= "$optionArray[factor] - $optionArray[valor]<br>";

}


I need them to be sorted ascending according to the key 'valor' so i tried using usort



usort($miarray, 'sort_valor');


with the following function I found in the examples given.



function sort_valor($a, $b)

{

    $a = $a['valor'];

    $b = $b['valor'];



    if ($a == $b) return 0;

    return ($a < $b) ? -1 : 1;

}


but I get the following error

The problem is your sort function is in the JavaScript portion of your code. Move it below the <?php tag in the file you'd like to reference it in (or include/require it from another PHP file).
