PHP 二维数组按照指定键排序（正序或倒叙均可）

    public static function array_sort( $array, $keys, $type='asc' ) {

        if( !isset( $array ) || !is_array( $array ) || empty( $array ) ) return '';

        if( !isset( $keys ) || trim( $keys ) == '' ) return '';

        if( !isset( $type ) || $type == '' || !in_array( strtolower( $type ), array( 'asc', 'desc' ) ) ) return '';

       

        $keysvalue  = [];

        foreach( $array as $key => $val ) {

            $val[ $keys ]   = str_replace( '-', '', $val[ $keys ] );

            $val[ $keys ]   = str_replace( ' ', '', $val[ $keys ] );

            $val[ $keys ]   = str_replace( ':', '', $val[ $keys ] );

            $keysvalue[]    = $val[ $keys ];

        }

       

        asort( $keysvalue ); //key值排序

        reset( $keysvalue ); //指针重新指向数组第一个

        foreach( $keysvalue as $key => $vals )

            $keysort[] = $key;

       

        $keysvalue  = [];

        $count      = count( $keysort );

        if( strtolower( $type ) != 'asc' ) {

            for( $i = $count - 1; $i >= 0; $i-- )

                $keysvalue[] = $array[ $keysort[ $i ] ];

        }else{

            for( $i = 0; $i < $count; $i++ )

                $keysvalue[] = $array[ $keysort[ $i ] ];

        }

        return $keysvalue;

    }
