Add new line to dynamically created js file

Question

I am using PHP to concatenate several Javascript files into one. I need to add new lines beforeeach part is added and have tried '\\n' but this throws an unknown character error. What is the correct character to indicate a new line?

file_put_contents($JSfile," /n ");


$jspart = file_get_contents($myfile);
file_put_contents($JSfile,'  '. $jspart  , FILE_APPEND);

Answer 1

您可以使用预定义的PHP常量PHP_EOL添加正确的“行尾”符号：

file_put_contents($JSfile, PHP_EOL);

Answer 2

Use only following in your Codes

$jspart = file_get_contents($myfile);
file_put_contents($JSfile, $jspart . "\n", FILE_APPEND);
