Question

基本上，我想在文本区域中输入文本，然后使用它们。例如

variable1:variable2@variable3
variable1:variable2@variable3
variable1:variable2@variable3

我知道我可以使用explode将每一行变成一个数组，然后使用foreach循环分别使用每一行，但是如何将三个变量分开使用呢？

Answer 1

除了preg_split：

$line = 'variable11:variable12@variable13';
print_r(preg_split('/[:@]/', $line));

/*
Array
(
    [0] => variable11
    [1] => variable12
    [2] => variable13
)
*/

你可以做preg_match_all：

$text = 'variable11:variable12@variable13
variable21:variable22@variable23
variable31:variable32@variable33';

preg_match_all('/([^\r\n:]+):([^\r\n@]+)@(.*)\s*/', $text, $matches, PREG_SET_ORDER);

print_r($matches);

/*
Array
(
    [0] => Array
        (
            [0] => variable11:variable12@variable13

            [1] => variable11
            [2] => variable12
            [3] => variable13
        )

    [1] => Array
        (
            [0] => variable21:variable22@variable23

            [1] => variable21
            [2] => variable22
            [3] => variable23
        )

    [2] => Array
        (
            [0] => variable31:variable32@variable33
            [1] => variable31
            [2] => variable32
            [3] => variable33
        )

)
*/

尝试preg_split http://php.net/manual/en/function.preg-split.php

如果有必要，你可以多次调用“爆炸”

如何拆分包含多个分隔符的列表？
