本文介绍了一个自定义的PHP函数sysSortArray，该函数能够按多个键名及指定的排序方式进行数组排序。通过示例展示了如何使用此函数进行复杂的数据排序。

<?php
function sysSortArray($ArrayData,$KeyName1,$SortOrder1 = "SORT_ASC",$SortType1 = "SORT_REGULAR")
{
if(!is_array($ArrayData))
{
return $ArrayData;
}
$ArgCount = func_num_args();
for($I = 1;$I < $ArgCount;$I ++)
{
$Arg = func_get_arg($I);
if(!eregi("SORT",$Arg))
{
$KeyNameList[] = $Arg;
$SortRule[] = '$'.$Arg;
}
else
{
$SortRule[] = $Arg;
}
}
foreach($ArrayData AS $Key => $Info)
{
foreach($KeyNameList AS $KeyName)
{
${$KeyName}[$Key] = $Info[$KeyName];
}
}
$EvalString = 'array_multisort('.join(",",$SortRule).',$ArrayData);';
eval ($EvalString);
return $ArrayData;
}
?>

示例如下：

<?php
$arr = array(
array(
'name' => '学习',
'size' => '1235',
'type' => 'jpe',
'time' => '1921-11-13',
'class' => 'D',
),
array(
'name' => '中国功夫',
'size' => '153',
'type' => 'jpe',
'time' => '2005-11-13',
'class' => 'J',
),
array(
'name' => '编程',
'size' => '35',
'type' => 'gif',
'time' => '1997-11-13',
'class' => 'A',
),
array(
'name' => '中国功夫',
'size' => '65',
'type' => 'jpe',
'time' => '1925-02-13',
'class' => 'D',
),
array(
'name' => '中国功夫',
'size' => '5',
'type' => 'icon',
'time' => '1967-12-13',
'class' => 'C',
),
);
print_r($arr);
//注意：按照数字方式排序时 153 比 65 小
$temp = sysSortArray($arr,"class","SORT_ASC","type","SORT_DESC","size","SORT_ASC","SORT_STRING");
echo "<pre>";
print_r($temp);
?>
