Initially i have an array list like this:
[
  [
    "hi",
    "hi",
    "hi",
    "",
    "hi",
    "2021-11-29 00:00:00",
    "4"
  ],
  [
    "custom title",
    "new custom",
    "customurl.com",
    "https://wpsn.test/wp-content/uploads/2021/09/vnech-tee-blue-1.jpg",
    "Custom Description",
    "2022-01-12 00:00:00",
    "4"
  ],
  [
    "new title",
    "suvro",
    "www.suvro.com",
    "",
    "new description",
    "2022-01-26 00:00:00",
    "4"
  ]
]
I want to add 'custom' at position 1 in each array - something like this:
[
  [
    "hi",
    "custom",
    "hi",
    "hi",
    "",
    "hi",
    "2021-11-29 00:00:00",
    "4"
  ],
  [
    "custom title",
    "custom",
    "new custom",
    "customurl.com",
    "https://wpsn.test/wp-content/uploads/2021/09/vnech-tee-blue-1.jpg",
    "Custom Description",
    "2022-01-12 00:00:00",
    "4"
  ],
  [
    "new title",
    "custom",
    "suvro",
    "www.suvro.com",
    "",
    "new description",
    "2022-01-26 00:00:00",
    "4"
  ]
]
What is the appropriate way to push this 'custom' in php, without iterating over the arrays?
