php - 如何在 php 中为 LaTeX 输出添加多个作者

Question

PHP代码：只能单作者。

if ($field == 'author') {
        $newVal = "";
        foreach (@split("\n", $value) as $refEntry) {
            if (strlen(trim($refEntry)) > 0) {
                $newVal .= "\IEEEauthorblockN{{$refEntry}}\n";
            }
        }
        $value = $newVal;

如何在 php 中编辑下面的代码，可以有\和？

\author{\IEEEauthorblockN{Authors Name/s per 1st Affiliation (Author)}
\IEEEauthorblockA{line 1 (of Affiliation): dept. name of organization\\
line 2: name of organization, acronyms acceptable\\
line 3: City, Country\\
line 4: Email: name@xyz.com}
\and
\IEEEauthorblockN{Authors Name/s per 2nd Affiliation (Author)}
\IEEEauthorblockA{line 1 (of Affiliation): dept. name of organization\\
line 2: name of organization, acronyms acceptable\\
line 3: City, Country\\
line 4: Email: name@xyz.com}
}
