遍歷數組可能是多維

Question

我可能有以下array()

Array([ 
    0 
]=>Array([ 
    part_id 
]=>6[ 
    part_user_id 
]=>2[ 
    part_department 
]=>3[ 
    part_category 
]=>1[ 
    part_subcategory 
]=>1[ 
    part_name 
]=>SparePart[ 
    part_qty 
]=>1[ 
    part_condition 
]=>New[ 
    part_description 
]=>Thisisadescription[ 
    part_image 
]=>images/parts/default.jpg)[ 
    1 
]=>Array([ 
    part_id 
]=>7[ 
    part_user_id 
]=>2[ 
    part_department 
]=>3[ 
    part_category 
]=>1[ 
    part_subcategory 
]=>1[ 
    part_name 
]=>SparePart[ 
    part_qty 
]=>1[ 
    part_condition 
]=>New[ 
    part_description 
]=>Thisisadescription[ 
    part_image 
]=>images/parts/default.jpg)) 

從我從MYSQL得到的數據，同樣的查詢也可能返回多行，所以我也收到此array()

Array([ 
    part_id 
]=>7[ 
    part_user_id 
]=>2[ 
    part_department 
]=>3[ 
    part_category 
]=>1[ 
    part_subcategory 
]=>1[ 
    part_name 
]=>SparePart[ 
    part_qty 
]=>1[ 
    part_condition 
]=>New[ 
    part_description 
]=>Thisisadescription[ 
    part_image 
]=>images/parts/default.jpg) 

我通過循環輸出在我的HTML

foreach($myResults as $row => $value){ 

} 

當我從數據庫中收到多於一行時，此循環將正常工作。如果我收到1行，我顯然會遇到問題。

對於我來說，爲了循環或根據我的結果簡單輸出來檢查我所收到的最佳方式是什麼？

Answer 1

檢查值是否爲數組。 如果是循環它。

if (is_array($value)) foreach ($value as $value2) {}
