【问题描述】：

我需要在 php 中生成 zeros 数组，但不知道如何使用 php 生成它。我可以用js来做。

在js数组中的零代码是：

for (let _i = 0; _i < 25; _i++) {
   let n = new Array(_i).fill(0)
   console.log(n);
}

像这样生成：

[]
[ 0 ]
[ 0, 0 ]
[ 0, 0, 0 ]
[ 0, 0, 0, 0 ]
[ 0, 0, 0, 0, 0 ]
[ 0, 0, 0, 0, 0, 0 ]
[ 0, 0, 0, 0, 0, 0, 0 ]
[ 0, 0, 0, 0, 0, 0, 0, 0 ]
[ 0, 0, 0, 0, 0, 0, 0, 0, 0 ]
[ 0, 0, 0, 0, 0, 0, 0, 0, 0, 0 ]
[ 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0 ]
[ 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0 ]
[ 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0 ]
[ 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0 ]
[ 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0 ]
[ 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0 ]
[ 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0 ]
[ 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0 ]
[ 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0 ]
[ 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0 ]
[ 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0 ]
[ 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0 ]
[ 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0 ]
[ 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0 ]

如何使用 php 数组生成这样的内容？

for (let _i = 0; _i < 25; _i++) {
  let n = new Array(_i).fill(0)
  console.log(n);
}

与array_fill
array_fill如何使用？
for ($i = 0; $i < 25; $i++) echo json_encode(array_fill(0, $i, 0)).PHP_EOL;3v4l.org/AL1o3

【解决方案1】：

array_fill()

for ($i = 0; $i < 25; $i++) {
    $n = array_fill(0, $i, 0);
    echo implode(', ', $n) . PHP_EOL; // output imploded for readable reasons
}
