從PHP陣列響應獲取某些值

Question

我試圖從陣列中提取["details"]使其顯示

Array Value 1=address 
Array Value 2=no_match 
Array Value 3=address_risk 
Array Value 4=low 

我嘗試以下，但它不返回任何值

foreach ($person as $key => $val) { 
    print "$key = $val\n"; 
} 

所以我應該能夠查詢陣列值if address="no_match" Print "no match"

Answer 1

此：

foreach ($person as $key => $val) { 
    print "$key = $val\n"; 
} 

應該是：

foreach ($person["details"] as $key => $val) { 
    print "$key = $val\n"; 
} 

原因：
要從嵌套的數組中拉出數組，需要放大與文件系統類似的差異[first_array] [second_array] ...

問題是_values屬性受到保護，而不是從類外部迭代時可見。對於一對夫婦的方式解釋訪問受保護的財產反正看到這樣一個問題：
