我有这个字符串（245）“- 当前地图 = VILLA - 当前任务 = VEGAS JUNKYARD、VILLA、PRESIDIO、KILL HOUSE、街道、三个王国赌场； - 可用任务 = TRAINYARD、IMPORT/EXPORT、MURDERTOWN、CQB 培训、炼油厂, 会议中心, 剧院;"
当前地图始终是一个值，当前任务和可用任务具有可变数量的值。
我想解析字符串，以便我有一个如下所示的数组：
Array ([Current Map] => VILLA [Current Missions] => Array ([0] => VEGAS JUNKYARD [1] => VILLA [2] => PRESIDIO [3] => KILL HOUSE [4] => STREETS [5] => THREE KINGDOMS CASINO) [Availible Missions] => Array ([0] => TRAINYARD [1] => IMPORT/EXPORT [2] => MURDERTOWN [3] => CQB TRAINING [4] => OIL REFINERY [5] => CONVENTION CENTER [6] => THEATER))
工作原理：它将 3 个主要部分（当前地图、当前任务、可用任务）分开
什么不起作用：将“当前任务”和“可用任务”的多个值分隔到一个数组中。
错误（或者我只是愚蠢）：注意“可用任务”之前的分号
$search_strs_maps = array('Current Map = ', '- Current Missions = ', '; - Available Missions = ', ';');
如果我把分号放在那里，即使我很确定分号在字符串中，它也找不到任何东西。
我提出这个的原因是，当我将分号放在“可用任务”之前时，我无法弄清楚为什么它没有找到任何东西，这让我发疯。此外，我还可以对代码进行第二次观察，并就如何使它变得更好提供一些建议。谢谢你的帮助！
这是我到目前为止所写的。
