我如何获得每个在<代码>外的一笔总款——最大_run——?

我试图这样做,但只回去了数据的第一价值,而不是所有数据。

foreach ($apijob_all as $value2){
   $sum_job_name = $value2[ sum_job_name ];
   $sum_max_run_time = $value2[ sum_max_run_time ];
}
print_r($sum_max_run_time);
问题回答

在PHP中,当你使用像 for一样的 lo时,变数与每 it相比都是多余的。 在休息室外获取<代码>总价值_max_run_time,考虑使用一个阵列储存这些数值。 样本代码如下:

$sum_max_run_times = array(); // Initialize an empty array

foreach ($apijob_all as $value2) {
    $sum_job_name = $value2[ sum_job_name ];
    $sum_max_run_time = $value2[ sum_max_run_time ];
 
    $sum_max_run_times[] = $sum_max_run_time;
}

print_r($sum_max_run_times); // Access all values outside the loop

This is sample output:
