preg_match() Help

I'm getting a preg_match warning and I don't see where the problem is in my regex code:

The warning:
PHP Warning: preg_match() Unknown modifier ']' in /var/www/html/Fetch_Refresh_TFR_Data.php on line 596

My php offending line:
$php_TFR_description = "/detail_\d_\d{4}.html\">[A-Za-z0-9,' /].*/";

What is the format you are trying to allow? Right now that last bracket is being escaped. Try this
$php_TFR_description = "/detail_\d_\d{4}.html\">[A-Za-z0-9].*/";

$php_TFR_description = "/detail_\d_\d{4}\.html\">[^<]*/m";


you also must:
- escape dot before html
- a better solution to fetch all until < is to use [^<]*
- use m modifier for multiline
