我对操作数组很糟糕......鉴于这种结构,我想删除顶级数组并将所有子集合并到一个平面数组中:
Array
(
[0] => Array
(
[0] => Array
(
[0] => hey.com
)
[1] => Array
(
[0] => you.com
)
)
[1] => Array
(
[0] => Array
(
[0] => this.com
)
[1] => Array
(
[0] => rocks.com
)
)
)
到所需的结构:
Array
(
[0] => hey.com
[1] => you.com
[2] => this.com
[3] => rocks.com
)
速度至关重要 - 我们将处理数十万个结果
