如何将一堆不同长度的数组合并为一个线性数组PHP [重复]

This question already has an answer here:

I have some author names of different books as listed below. some of has one author name some has two and three and so on. This is my array: (PHP, Laravel)

array:10 [▼
  0 => "["Yashavant P. Kanetkar"]"
  1 => "["Jordan Krause"]"
  2 => "["Christopher Negus","James","McKnight"]"
  3 => "["Richard Petersen"]"
  4 => "["Das", "Sumitabha"]"
  5 => "["Groff", "James"]"
  6 => "["Martin Reddy"]"
]

And I want to convert to this:

array:10 [▼
  0 => "["Yashavant P. Kanetkar"]"
  1 => "["Jordan Krause"]"
  2 => "["Christopher Negus"]"
  3 => "["James"]"
  4 => "["McKnight"]"
  5 => "["Richard Petersen"]"
  6 => "["Das"]"
  7 => "["Sumitabha"]"
  8 => "["Groff"]"
  9 => "["James"]"
  10 => "["Martin Reddy"]"
]
