我有这个数组$ data:
Array
(
[0] => 86086
[1] => Arnel
[2] => Paras
)
Array
(
[0] => 86085
[1] => Arnely
[2] => Para
)
Array
(
[0] =>
)
如何删除完全不包含任何值的底部数组,因此仅包含:
Array
(
[0] => 86086
[1] => Arnel
[2] => Paras
)
Array
(
[0] => 86085
[1] => Arnely
[2] => Para
)
我尝试使用array_filter($ data,strlen),它只是这样做:
Array
(
)

array_pop()弹出并返回数组的最后一个元素的值,将数组缩短一个元素,即可完成您所描述的操作。答:
array_shift()做相反的操作(从数组中删除第一个元素并返回值)
因此您可以执行以下操作:
$firstVal = array_pop($data)
或者只是
array_pop($data)
取决于是否要返回该值。
