在多个分隔符上爆炸()

Question

我试图用多个分隔符爆炸()。

用分隔符：

• "&“
• “和”
• "/“
• "，“

以便，例如，如果我有一个数组：

<?php
    $lol = array(
        "Strawberry/Blueberry/Raspberry",
        "Strawberry, Blueberry, Raspberry",
        "Strawberry & Blueberry & Raspberry",
        "Strawberry and Blueberry and Raspberry",
        "Strawberry, Blueberry and Raspberry",
        "Strawberry, Blueberry, Raspberry",
    );
?>

它将输出如下：

<?php
    $lol = array(
        array("Strawberry","Blueberry","Raspberry"),
        array("Strawberry","Blueberry","Raspberry"),
        array("Strawberry","Blueberry","Raspberry"),
        array("Strawberry","Blueberry","Raspberry"),
        array("Strawberry","Blueberry","Raspberry"),
        array("Strawberry","Blueberry","Raspberry"),
    );
?>

有没有一种有效的方法来做到这一点？

Answer 1

for($i=0;$i<count($lol);$i++){
    $lol[$i] = preg_split("@(\s*and\s*)?[/\s,&]+@", $lol[$i]);
}

Answer 2

可以将分隔符替换为explode()将接受的通用分隔符：

foreach($lol as $key => $current) {
    $bits = explode(',', stri_replace(array('/', '&', 'and'), ',', $current));
    $lol[$key] = $bits;
}

Answer 3

您可以使用preg_split() -然后使用正则表达式来表示"a或b或c“。

示例：

<?php
    $lol = array(
        "Strawberry/Blueberry/Raspberry",
        "Strawberry, Blueberry, Raspberry",
        "Strawberry & Blueberry & Raspberry",
        "Strawberry and Blueberry and Raspberry",
        "Strawberry, Blueberry and Raspberry",
        "Strawberry, Blueberry, Raspberry",
    );
    $s = "/\/|, | & | and /";
    foreach ($lol as $v) {
      print_r(preg_split($s, $v));
    }
?>

输出：

Array
(
    [0] => Strawberry
    [1] => Blueberry
    [2] => Raspberry
)

    [0] => Strawberry
    [1] => Blueberry
