گرفتن value در آرایه بیش از سه بعد
0
با عرض سلام و ادب خدمت استاد گرامی و همه دوستان عزیز
من یک آرایه بیش از سه بعد رو نوشتم، ولی نمیدونم به چه صورت به یک سری value خاص دسترسی داشته باشم.
برای مثال در این آرایه میخوام به value های ‘score’ همه ی دانش آموزان دسترسی داشته باشم.
کدهای بنده و همچنین روش هایی که برای echo استفاده کردم به این صورته: (البته فایل رو هم ضمیمه میکنم)

علیک سلام پویا جان
راه حل که زدم حلقه تو در تو هستش٬ از نظر الگوریتمی زمان اش زیاده اما برای این مسئله جواب میده
تو این حلقه foreach وقتی value بر میگردونه اون یک آرایه هست
منم از این آرایه که بر میگردونه برای حلقه بعدی استفاده کردم تا که به قیمت score رسیدم
امیدوارم مشکلت رو حل کرده باشم
سپاس
foreach($students as $key => $value){
echo"$key: <br>";
foreach($value as $key2 => $value2){
echo "$key2: <br>";
foreach($value2 as $key3 => $value3){
echo "$key3 = {$value3["score"]} <br>";
}
}
}
