PHP Minifier Causes Parse Error

[taufik-nurrohman]

[16-Oct-2021 12:18:44 UTC] PHP Parse error: syntax error, unexpected '' (T_ENCAPSED_AND_WHITESPACE), expecting '-' or identifier (T_STRING) or variable (T_VARIABLE) or number (T_NUM_STRING) in .\lot\x\panel\engine\f\route.php on line 15

PHP Version: 7.2.7

On line 15 of .\lot\x\panel\engine\f\route.php is a HEREDOC syntax:

$content=<<<S
Stuff goes here.
S;$_['title']='Etc...';

Adding a line break just after the ; fixed the issue:

$content=<<<S
Stuff goes here.
S;
$_['title']='Etc...';

HA! Just found the spec for older PHP version:

Prior to PHP 7.3.0, it is very important to note that the line with the closing identifier must contain no other characters, except a semicolon (;). That means especially that the identifier may not be indented, and there may not be any spaces or tabs before or after the semicolon. It's also important to realize that the first character before the closing identifier must be a newline as defined by the local operating system. This is \n on UNIX systems, including macOS. The closing delimiter must also be followed by a newline.
