what different between following commands when creating container in docker? docker run -d -p 8080 sample/image and docker run -d -p 8080:8080 sample/image i have seen majority of them use second command, not sure if mean different things, or if first shorthand. i couldn't find material on this. docker run -d -p 8080 sample/image exposes port 8080 of container arbitrary port on host. port is docker. whereas, docker run -d -p 8080:8080 sample/image exposes port 8080 of container port 8080 on host. in both cases, can see mapping using docker inspect , or docker ps : 380af8c2bcc6 ubuntu "bash" 15 seconds ago 13 seconds 0.0.0.0:32768->1234/tcp elegant_meitner in case, port 1234 of container exposed port 32768 on host.

regex - PHP remove numbers in brackets -

-
i have string looks following in php: foo [123][bar] , i'd remove [123] string entirely end foo [bar] . another example blah [9484][m0200 blah blah blah] makes things more complicated because can't remove numbers , remove empty brackets. first set of brackets contains 3-4 digit number, , never letters, second brackets can contain anything. any suggestions how i'd go doing this? thanks. this regex \[\d{3,4}\] will find 3-4 digit numbers inside brackets. demo: https://regex101.com/r/kh3nz5/1 used preg_replace, http://php.net/manual/en/function.preg-replace.php , replace found instances. echo preg_replace('~\[\d{3,4}\]~', '', 'blah [9484][m0200 blah blah blah]'); output: blah [m0200 blah blah blah] \d single number , {3,4} says @ least 3 occurrences of number , no more 4. pages more detailed info on regexs, http://www.rexegg.com/ http://www.regular-expressions.info/
