PHP : 如何将一个字符串分成 4 个部分？

Question

我正在尝试将一个字符串分成 4 个部分：

$str = 'Bill Gates - Founder and CEO - Microsoft'

$first_name = 'Bill';
$last_name = 'Gates';
$position = 'Founder and CEO';
$company= 'Microsoft';

如何在 PHP 中实现这些目标？我觉得我必须使用破折号和空格...但无法弄清楚哪个功能最有效...有什么想法吗？

非常感谢！

Answer 1

使用分解字符串

https://www.php.net/manual/en/function.explode.php

1.

你可以说用 [white-space] 分割字符串，但在这种情况下你会得到

$return_array = explode(" ", "Bill Gates - Founder and CEO - Microsoft");

["Bill", "Gates", "-", "Founder", "and", "CEO", "-", "Microsoft"]

2.

如果你说用 [white-space 破折号 white-space] 分割，你会得到

$return_array = explode(" - ", "Bill Gates - Founder and CEO - Microsoft");

["Bill Gates", "Founder and CEO", "Microsoft"]

Answer 2

如果对于名称部分，您假设总是至少有两个词，您可以创建一个非常简单的正则表达式来一次性获取它：

$str = 'Bill Gates - Founder and CEO - Microsoft';
preg_match('/^(.+) (.+) - (.+) - (.+)$/', $str, $parts);

print_r($parts);

/*
Array
(
    [0] => Bill Gates - Founder and CEO - Microsoft
    [1] => Bill
    [2] => Gates
    [3] => Founder and CEO
    [4] => Microsoft
)
*/

或者如果您不想使用数组索引 1 到 4，则使用命名组：

$str = 'Bill Gates - Founder and CEO - Microsoft';
preg_match('/^(?P<firstName>.+) (?P<lastName>.+) - (?P<position>.+) - (?P<company>.+)$/', $str, $parts);

print_r($parts);

/*
Array
(
    [firstName] => Bill
    [lastName] => Gates
    [position] => Founder and CEO
    [company] => Microsoft

// but also:
    [0] => Bill Gates - Founder and CEO - Microsoft
    [1] => Bill
    [2] => Gates
    [3] => Founder and CEO
    [4] => Microsoft
)
*/

要完成 uVolpus 答案：

'explode' 是这种情况下的最佳解决方案，但重要的是对数组进行双重分解以获得名字和姓氏。

完整代码如下：

   $str = 'Bill Gates - Founder and CEO - Microsoft';
   $array = explode(" - ", $str);
   $new_array = array();
   $new_array['full_name'] =  $full_name = $array[0];
   $new_array['first_name'] = $first_name = explode(' ',$array[0])[0];
   $new_array['last_name'] = $last_name = explode(' ',$array[0])[1];;
   $new_array['position'] = $position = $array[1];
   $new_array['company'] = $company = $array[2];

   echo "new_array"; print_r($new_array);
