There is a line "# 1104, # 1104, # 1108 geg787, 894654" you must have written a regular schedule that checks for the presence of such a symbol # in front of numbers. Implemented it on js, how to write the same on php
str="#1104, #1104, #1108 geg787 , 894654" re = /#(\d+)/ig found = str.match(re) 
gkey is superfluous. - PinkTux/#(\d+)/i. Or do you read aloud the chapter from a tutorial about PHP and regular expressions? Sorry, this is not for me, but, for example, in Google, or here: php.su/preg_match - PinkTux
