PHP file_put_contents无法正常工作

Question

I have this code and it does not update the file. What am I doing wrong here?

$html = file_get_contents('/srv/www/htdocs/code.html');
$lastmon = Date("m", strtotime("first day of previous month"));
$html_r = str_replace('<strong>CODE_'.$lastmon.'</strong>', '<strong>CODE_'.Date("m").'</strong>', $html);
file_put_contents('/srv/www/htdocs/code.html', $html_r);

Answer 1

$html = file_get_contents('/srv/www/htdocs/code.html');
$lastmon = date("m", strtotime("first day of previous month"));
$html_r = str_replace('<strong>CODE_'.$lastmon.'</strong>',     '<strong>CODE_'.date("m").'</strong>', $html);
file_put_contents('/srv/www/htdocs/code.html', $html_r);

There's a function date() (and a class DateTime) and maybe you don't know that php is case sensitive.

Be sure that:

• the file path is correct
• php has permissions to read from and write to the file

Answer 2

Actually, I found another way to set the code correctly in the template vs. changing the HTML. I will use PHP in the template to retrieve it from the database vs. having to change it on the fly.
