我有這樣的陣列去除空值密鑰值對distors訂購關聯數組
[1] => Array
(
[Assembly required] => Yes
[Max load (kg)] => 120
[Product weight (kg)] =>
[Warranty (years)] => 3
[Height adjustable] => Yes
[Lumbar support] =>
[Back tilt adjustment] => Yes
[Seat tilt adjustment] => Yes
[Chair height range (mm)] => 880 - 950
[Chair seat width (mm)] => 500
[Chair seat depth (mm)] => 480
[Chair back height (mm)] => 410
[Chair back width (mm)] => 420
[Seat height range (mm)] => 440 - 580
[AFRDI Approved] =>
[Optional adjustable arms] => Yes
[image] => https://cdn.shopify.com/s/files/1/1249/7859/files/Chair.png?18135080827462508830
)
以上陣列的的var_dump是
[1]=>
array(17) {
["Assembly required"]=>
string(3) "Yes"
["Max load (kg)"]=>
string(3) "120"
["Product weight (kg)"]=>
string(0) ""
["Warranty (years)"]=>
string(1) "3"
["Height adjustable"]=>
string(3) "Yes"
["Lumbar support"]=>
string(0) ""
["Back tilt adjustment"]=>
string(3) "Yes"
["Seat tilt adjustment"]=>
string(3) "Yes"
["Chair height range (mm)"]=>
string(9) "880 - 950"
["Chair seat width (mm)"]=>
string(3) "500"
["Chair seat depth (mm)"]=>
string(3) "480"
["Chair back height (mm)"]=>
string(3) "410"
["Chair back width (mm)"]=>
string(3) "420"
["Seat height range (mm)"]=>
string(9) "440 - 580"
["AFRDI Approved"]=>
string(0) ""
["Optional adjustable arms"]=>
string(3) "Yes"
["image"]=>
string(80) "https://cdn.shopify.com/s/files/1/1249/7859/files/Chair.png?18135080827462508830"
}
我想從上面卸下空白值對。
foreach($singlearr as $key=>$value){
if(is_null($value) || $value == '')
unset($singlearr[$key]);
}
這除去鍵 - 值對的值是空但它在以下順序扭曲序列。
[1] => Array
(
[Assembly required] => Yes
[Max load (kg)] => 120
[Warranty (years)] => 3
[Height adjustable] => Yes
[Back tilt adjustment] => Yes
[Chair height range (mm)] => 880 - 950
[Chair seat width (mm)] => 500
[Chair seat depth (mm)] => 480
[Chair back height (mm)] => 410
[Chair back width (mm)] => 420
[Seat height range (mm)] => 440 - 580
[image] => https://cdn.shopify.com/s/files/1/1249/7859/files/Chair.png?18135080827462508830
[Seat tilt adjustment] => Yes
[Optional adjustable arms] => Yes
)
結果陣列的var_dump形式:
[1]=>
array(14) {
["Assembly required"]=>
string(3) "Yes"
["Max load (kg)"]=>
string(3) "120"
["Warranty (years)"]=>
string(1) "3"
["Height adjustable"]=>
string(3) "Yes"
["Back tilt adjustment"]=>
string(3) "Yes"
["Chair height range (mm)"]=>
string(9) "880 - 950"
["Chair seat width (mm)"]=>
string(3) "500"
["Chair seat depth (mm)"]=>
string(3) "480"
["Chair back height (mm)"]=>
string(3) "410"
["Chair back width (mm)"]=>
string(3) "420"
["Seat height range (mm)"]=>
string(9) "440 - 580"
["image"]=>
string(80) "https://cdn.shopify.com/s/files/1/1249/7859/files/Chair.png?18135080827462508830"
["Seat tilt adjustment"]=>
string(3) "Yes"
["Optional adjustable arms"]=>
string(3) "Yes"
}
爲例如。在上面這個結果數組中,[image]
就像上面這樣移動。
使用此刪除您的空數組中的值字段$ arr = array_filter($ arr); –
@NaveenKumar @jaimin array_filter()刪除空我不需要檢查,但它也扭曲了以前的順序。我正在從'CSV'文件中讀取數組 –
