我有这个数组
[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
)
上面数组的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"
}
我想从上面删除空白值对。
foreach($singlearr as $key=>$value){
if(is_null($value) || $value == '')
unset($singlearr[$key]);
}
此删除的键值对的值为null 但它按顺序扭曲了序列。
[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
)
结果数组var_dump form：
[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"
}
例如。在上面的结果数组中，[image]向上移动，就像这样。
