Question

我有一个用“|”分隔的数组。我想做的是用这个标识符分开。

数组如下： -

myid1|My Title|Detailed Description
myid2|My Title|Second Row Description
myid3|My Title|Third row description

我所做的是我在其上使用explode来获得我想要的结果。

$required_cells = explode('|', $bulk_array);

但问题是（如下所示）只有我的第一个阵列被正确爆炸，并且下一个阵列的下一个第一个单元格由于“新行”而混合。

我是否可以在连续的数组单元格中获取上层数组？

Array
(
    [0] => myid1
    [1] => My Title 
    [2] => Detailed Description
myid2
    [3] => My Title 
    [4] => Second Row Description
myid3
    [5] => My Title 
    [6] => Second Row Description
)

Answer 1

您可以使用preg_split在|和EOL：

上爆炸

$parts = preg_split('#(\||\r\n|\r|\n)#', $string); // EOL is actually 3 different types

这使得1个阵列包含9个元素。

或首先在EOL上爆炸，然后在|上爆炸：

$lines = preg_split('#(\r\n|\r|\n)#', $string);
$lines = array_map(function($line) {
  return explode('|', trim($line));
});

这使得3个数组各有3个元素。

Answer 2

首先爆炸新行，又称"\n"，然后遍历该数组并在管道上爆炸，又名'|'

$bulk_array = "myid1|My Title|Detailed Description
myid2|My Title|Second Row Description
myid3|My Title|Third row description";

$lines = explode("\n", $bulk_array);

foreach ($lines as $key => $line)
{
    $lines[$key] = explode('|', $line);
}

然后print_r($lines);将输出：

Array
(
    [0] => Array
        (
            [0] => myid1
            [1] => My Title
            [2] => Detailed Description
        )

    [1] => Array
        (
            [0] => myid2
            [1] => My Title
            [2] => Second Row Description
        )

    [2] => Array
        (
            [0] => myid3
            [1] => My Title
            [2] => Third row description
        )

）

Answer 3

您可以使用array_map：

$str = "myid1|My Title|Detailed Description
  myid2|My Title|Second Row Description
  myid3|My Title|Third row description";

$newLine = (explode("\n", $str));
$temp = array();
$result = array_map(function($someStr) use(&$temp) { 
  $exploded = explode("|", $someStr); 
  foreach($exploded as $value) $temp[] = $value;
}, $newLine); 

print_r($temp);

Sandbox example，如果你不需要它展平你可以放弃foreach部分：

$str = "myid1|My Title|Detailed Description
  myid2|My Title|Second Row Description
  myid3|My Title|Third row description";

$newLine = (explode("\n", $str));
$result = array_map(function($someStr) { 
  return explode("|", $someStr); 
}, $newLine); 

print_r($result);

在PHP中爆炸一个包含新行的数组
