php çoklu dizileri sıralamak multiarray sort
PHP- Kodu:
function SortDataSet($aArray, $sField, $bDescending = false)
{
$bIsNumeric = IsNumeric($aArray);
$aKeys = array_keys($aArray);
$nSize = sizeof($aArray);
for ($nIndex = 0; $nIndex < $nSize - 1; $nIndex++)
{
$nMinIndex = $nIndex;
$objMinValue = $aArray[$aKeys[$nIndex]][$sField];
$sKey = $aKeys[$nIndex];
for ($nSortIndex = $nIndex + 1; $nSortIndex < $nSize; ++$nSortIndex)
{
if ($aArray[$aKeys[$nSortIndex]][$sField] < $objMinValue)
{
$nMinIndex = $nSortIndex;
$sKey = $aKeys[$nSortIndex];
$objMinValue = $aArray[$aKeys[$nSortIndex]][$sField];
}
}
$aKeys[$nMinIndex] = $aKeys[$nIndex];
$aKeys[$nIndex] = $sKey;
}
$aReturn = array();
for($nSortIndex = 0; $nSortIndex < $nSize; ++$nSortIndex)
{
$nIndex = $bDescending ? $nSize - $nSortIndex - 1: $nSortIndex;
$aReturn[$aKeys[$nIndex]] = $aArray[$aKeys[$nIndex]];
}
return $bIsNumeric ? array_values($aReturn) : $aReturn;
}
function IsNumeric($aArray)
{
$aKeys = array_keys($aArray);
for ($nIndex = 0; $nIndex < sizeof($aKeys); $nIndex++)
{
if (!is_int($aKeys[$nIndex]) || ($aKeys[$nIndex] != $nIndex))
{
return false;
}
}
