使用PHP从通用文件构造JavaScript代码时出现“SyntaxError：unterminated string literal”

Question

I'm trying to use PHP to generate a JavaScript switch block by taking input from TemplateList.txt. It works fine when I only have one line in TemplateList.txt, but when I have two or more I get an error in the console saying I have a

SyntaxError: unterminated string literal

on the line of the php opening tag, I can't see any unclosed strings.

<?php 
$listHandle = fopen('templates/TemplateList.txt', 'r');

while (!feof($listHandle)) {                    
   $thisTemplate = fgets($listHandle);   
   echo "case \"" . $thisTemplate . "\": " . $thisTemplate . "();  break; "; 
}  

fclose($listHandle);
?>

My TemplateList.txt file looks like this:

heart_by_john
dog_by_sue

What am I doing wrong?

Answer 1

The fgets() function includes the line break in the returned string, so you add a line break to your JS inside the string. Replace

$thisTemplate = fgets($listHandle);

by

$thisTemplate = trim(fgets($listHandle));
