Php 获取索引行的子数组列的和
我有一系列客户/人员，他们拥有与该客户相关的项目子阵列。项目分为两种类型：“typeJob”或“typePipeline”。我需要按客户对projects子数组中各个列的值进行求和（特别是第5、6、7列-表示第1个月、第2个月和第3个月的收入） 我尝试了各种可能的方法，包括下面的方法，但我似乎总是以测试整个数组而不是每一行是否满足条件为结束，或者如果我选择了for each循环生成错误的方式，因为要么是数组/单个值不匹配，要么是条件没有任何作用 这是我最近试过的。它的工作原理是检查数组中是否有“typeJob”，但如果为客户的任何项目找到了“typeJob”，则对所有行（即使是没有“typeJob”的行）求和。我想排除找不到“typeJob”的行Php 获取索引行的子数组列的和,php,arrays,Php,Arrays,我有一系列客户/人员，他们拥有与该客户相关的项目子阵列。项目分为两种类型：“typeJob”或“typePipeline”。我需要按客户对projects子数组中各个列的值进行求和（特别是第5、6、7列-表示第1个月、第2个月和第3个月的收入） 我尝试了各种可能的方法，包括下面的方法，但我似乎总是以测试整个数组而不是每一行是否满足条件为结束，或者如果我选择了for each循环生成错误的方式，因为要么是数组/单个值不匹配，要么是条件没有任何作用 这是我最近试过的。它的工作原理是检查数组中是否有“

在对值求和之前，可以过滤
$row['projects']foreach ($arrays as $row) {
$typeJobs = array_filter($row['projects'], function ($v) { return $v[0] == 'typeJob'; });
$job_total1[$row['Client']] = array_sum(array_column($typeJobs,5));
$job_total2[$row['Client']] = array_sum(array_column($typeJobs,6));
$job_total3[$row['Client']] = array_sum(array_column($typeJobs,7));
}
它可能会更快地循环通过他们，并保持一个总运行
foreach ($arrays as $row) {
$totals = [0,0,0];
foreach ( $row['projects'] as $project ) {
if ( $project[0] == 'typeJob' ) {
$totals[0] += $project[5];
$totals[1] += $project[6];
$totals[2] += $project[7];
}
}
$job_total1[$row['Client']] = $totals[0];
$job_total2[$row['Client']] = $totals[1];
$job_total3[$row['Client']] = $totals[2];
}
它看起来不像使用
array\uu…var_export（）
