PHP - 使用explode创建数组

Question

我的php问题如下：

我有这个字符串：$days="Monday* Tuesday* Wednesday*"

我想创建一个这样的数组：$d[1]="Monday"; $d[2]="Tuesday"; $d[3]="Wednesday"

我感觉解决方案经过explode(*, $days)，但我无法进一步

感谢您的帮助：）

Answer 1

$days="Monday* Tuesday* Wednesday*";
$d=explode('* ', $days);

或

$days="Monday* Tuesday* Wednesday*";
$d=explode(' ', str_replace('*','',$days));

在最后一个单词的末尾排除“*”。

Answer 2

explode('* ', trim($days, '*'));

Answer 3

您应该使用：

explode("* ", $days)

但IMO，我会像这样使用昏迷：

$days  = "Monday,Tuesday,Wednesday";
$days = explode(",", $days);
echo $days[0]; // => Monday
echo $days[1]; // => Tuesday

Answer 4

$days="Monday* Tuesday* Wednesday*";
$exploded = explode('* ',substr($days, 0, -1));
print_r($exploded);

输出：

Array
(
    [0] => Monday
    [1] => Tuesday
    [2] => Wednesday
)

Answer 5

<?php
$days = 'Monday* Tuesday* Wednesday*';
$d = array_filter(explode('* ', $days));
