PHP读取每一行

Question

我有<textfield>（$_POST['list']）。

如何获取数组键的每一行的值？

示例：

<textfield name="list">Burnett River: named by James Burnett, explorer
Campaspe River: named for Campaspe, a mistress of Alexander the Great
Cooper Creek: named for Charles Cooper, Chief Justice of South Australia 1856-1861
Daintree River: named for Richard Daintree, geologist
</textfield>

应转换为：

Array(
[Burnett River: named by James Burnett, explorer]
[Campaspe River: named for Campaspe, a mistress of Alexander the Great]
[Cooper Creek: named for Charles Cooper, Chief Justice of South Australia 1856-1861]
[Daintree River: named for Richard Daintree, geologist]
)

感谢。

Answer 1

使用explode函数，然后修剪结果数组（去除任何剩余的\n，\r或任何意外的空格/标签符号）：

$lines = explode("\n", $_POST['list']);
$lines = array_map('trim', $lines);

Answer 2

这是最安全的方法。它并不假设您可以丢弃回车符（\r）字符。

$list_string = $_POST['list'];

// \n is used by Unix. Let's convert all the others to this format

// \r\n is used by Windows
$list_string = str_replace("\r\n", "\n", $list_string);

// \r is used by Apple II family, Mac OS up to version 9 and OS-9
$list_string = str_replace("\r", "\n", $list_string);

// Now all carriage returns are gone and every newline is \n format
// Explode the string on the \n character.
$list = explode("\n", $list_string);

您可以使用explode()并在换行符\n处展开。

$array = explode("\n", $_POST['list']);

explode("\n", $_POST['list'])
