将特定格式的文本转换为真正的 PHP 代码分配

我在将特定格式的文本放入实际工作的PHP代码中遇到了一些问题。

我的文本文件：

@T1:The German sociologist Max Weber once proposed
@S:Jos Bleau
@C:jos.bleau@domain.com
@L:"He used to be so conservative," she says, throwing up her hands in mock exasperation. "We used to have the worst arguments right here at this table. I was part of the first group of public city school teachers that struck to form a union, and Richard was very angry with me. He saw unions as corrupt. He was also very opposed to social security. He thought people could make much more money investing it on their own. Who knew that within 10 years he would become so idealistic
@R:At first, <@Ri>Stallman viewed these notices<@$p> with alarm. Rare was the software program that didn't borrow source code from past programs, and yet, with a single stroke of the president's pen, Congress had given programmers and companies the power to assert individual authorship over communally built programs. It also injected a dose of formality into what had otherwise been an informal system.
The AI Lab of the 1970s was by all accounts a special place. Cutting-edge projects and top-flight researchers gave it an esteemed position in the world of computer science. The internal hacker culture and its anarchic policies lent a rebellious mystique as well. Only later, when many of the lab's scientists and software superstars had departed, would hackers fully realize the unique and ephemeral world they had once inhabited.
As a single parent for nearly a decade-she and Richard's father, Daniel Stallman, were married in 1948, divorced in 1958, and split custody of their son afterwards-Lippman can attest to her son's aversion to authority. She can also attest to her son's lust for knowledge. It was during the times when the two forces intertwined, Lippman says, that she and her son experienced their biggest battles.
@ST:Fusions
@R:Such mythological descriptions, while extreme, underline an important fact. The ninth floor of 545 Tech Square was more than a workplace for many. For hackers such as Stallman, it was home.
The belief in individual freedom over arbitrary authority extended to school as well. Two years ahead of his classmates by age 11, Stallman endured all the usual frustrations of a gifted public-school student. It wasn't long after the puzzle incident that his mother attended the first in what would become a long string of parent-teacher conferences.

我需要的预期输出(半伪代码;未转义的引号(：

<?php
$title1 = 'The German sociologist Max Weber once proposed';

注意：

• 像$title1和@T1这样的名称彼此完全无关，$title1只是用作示例。它也可能是$xy或其他东西

• 如果@XY在文件中多次出现，则应将值添加为数组元素，否则作为简单赋值添加

我不知道preg_split()方向是否正确，我可以用它来做吗？还是我必须使用其他功能来完成此操作？
