排序关联数组

标签： php arrays sorting associative-array

以前曾有人问过这个问题，但给出的例子对我没有用。

我有一个带有两个键的数组

$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),
);

如果我遍历数组，则会按原始顺序获得输出

foreach ($miarray as $optionArray){ 
$pr .= "$optionArray[factor] - $optionArray[valor]<br>";
}

我需要根据键“ valor”对它们进行升序排序，所以我尝试使用usort 

usort($miarray, 'sort_valor');

具有以下示例中提供的以下功能。

function sort_valor($a, $b)
{
    $a = $a['valor'];
    $b = $b['valor'];

    if ($a == $b) return 0;
    return ($a < $b) ? -1 : 1;
}

但出现以下错误

  

[2018年11月20日19:12:08 UTC] PHP警告：usort（）需要参数2   是有效的回调，未找到函数'sort_valor'或无效   xxxxxxxxxxx中的函数名称

我使用以下两个文件

问题在于您的排序功能在代码的JavaScript部分中。将其移动到您要引用的文件中的<?php标记下（或从另一个PHP文件中将其include / require移到该标记下）。
