Question

我会计算ID存在的次数，以便将我的表格的单元格与rowspan合并。我认为要进行查询，但资源过于密集，页面显示速度很慢。我尝试计算值出现的次数＆＃34; array_count_values＆＃34;但它不起作用。我使用Wordpress进行预告。

查询结果

BAKU (ID:3138)  RACE 1
BAKU (ID:3138)  RACE 2
MONZA (ID:1)    RACE
....

预期结果

BAKU (ID:3131)  RACE 1
                RACE 2
MONZA (ID:1)    RACE
....

查询

$sqlcalendarcurrentweek=$wpdb->get_results("SELECT race.entrant, team_nat, chassis.chassis, engine.engine, driver.driver, driver_code, driver_nation,

$countidcircuit=array();
foreach($sqlcalendarcurrentweek as $rowcalendarcurrentweek):
   $countidcircuit[] = $rowcalendarcurrentweek->id_circuit; 
   $resultcountidcircuit= array_count_values($countidcircuit);
   $countresultcountidcircuit= $resultcountidcircuit[$rowcalendarcurrentweek->id_circuit]
var_dump($countresultcountidcircuit);
   echo '<td rowspan="'.$countresultcountidcircuit.'">'.multiplecountry($rowcalendarcurrentweek->calendar_nation,'').' <a href="'.get_home_url().'/'.pll__('circuits').'/'.$rowcalendarcurrentweek->circuit_code.'/" title="'.$rowcalendarcurrentweek->calendar_circuit_name.'">'.$rowcalendarcurrentweek->circuit_town.'</a></td>';

endforeach;

var_dump结果

array(1) { 
    [3138]=> int(1) 
} 
array(2) { 
    [3138]=> int(1) [1]=> int(1) 
}

如何让2到巴库和1为蒙扎？
