我正在寻找一段代码，可以检查一个＆＃34;字的一部分＆＃34;在多维数组中。
foreach($teamMembers as $key => $value){
if(preg_match('/^1.1./', $key)){
$countCount += $key;
$answerCount++;
}
}
我试过用这个，但没有运气。
我需要在key以＆＃39; 1.1开头时计算所有数字。＆＃39;
它位于多维数组中。也许这就是它无法正常工作的原因？
我需要从中获取数据的地方总是不同的。
$teamMembers[0]
$teamMembers[1]等。

下一行代码几乎完全有效。
$count=0;
foreach($teamMembers[0] as $item){
if(is_array($item)){
foreach($item as $k=>$v){
if(strpos($k,'1.1')===0){
$count += $v;
}
}
}
}
但我需要$teamMembers[0]进入$ teamMembers[0]['antwoord']. Else it'll pick up wrong data. Does anyone know how I can get this implemented? Just putting '['antwoord']后面的方向，并将所有0作为输出。
答案 0 :(得分：1)
您可以迭代每个子阵列并使用array_filter()致电strpos()，然后将该计数添加到总计数中。
代码：（Demo）
$count=0;
foreach($teamMembers as $item){
if(is_array($item)){
$count+=sizeof(array_filter($item,function($k){return strpos($k,'1.1.')===0;},ARRAY_FILTER_USE_KEY));
}
}
echo $count;
输出：
6
这是带循环的相同类型的方法：
$count=0;
foreach($teamMembers as $item){
if(is_array($item)){
foreach($item as $k=>$v){
if(strpos($k,'1.1.')===0){
++$count;
}
}
}
}
echo $count;
...此外
如果要定位特定子阵列并计算其中有多少个关联元素具有以某个子字符串开头的键，则可以使用：
function count_keys_beginning_with($array,$substring){
return sizeof(array_filter($array,function($k)use($substring){return strpos($k,$substring)===0;},ARRAY_FILTER_USE_KEY));
}
echo count_keys_beginning_with($teamMembers['antwoord'],'1.1.');
// output: 3
或者没有自定义函数调用：
$answer_count=sizeof(array_filter($teamMembers['antwoord'],function($k){return strpos($k,'1.1.')===0;},ARRAY_FILTER_USE_KEY));
echo $answer_count;
// output: 3

array_walk_recursive + strpos解决方案：
$teamMembers = [
'responderScoRev' => 'Score',
'antwoord' => ['1.2. text' => 1, '1.1.2 text' => 1, '1.1.3 text' => 1],
'1.1.3' => 3
];
$cnt = 0;
array_walk_recursive($teamMembers, function($v, $k) use(&$cnt){
if (strpos($k, '1.1.') === 0) $cnt++;
});
print_r($cnt);
