regex - Extracting substrings ending with "mp4" -


i have following input:

string='get........ref=mp4;get........ref=flv;get........ref=mp4;'

it has 3 segments. need extract segments ending mp4;.

ie. 

get........ref=mp4 get........ref=mp4

the current result match get........ref=mp4 , get........ref=flv;get........ref=mp4;.

my regular express: get(.*?)mp4

i don't need long match containing flv inside, , regex not work: get(.*?)(?!:flv)mp4

i don't know how solve , appreciated.

you can explode semi-colon separated list , use preg_grep elements end mp4:

$string='get........ref=mp4;get........ref=flv;get........ref=mp4;'; $res = explode(";", $string); $res = preg_grep('/mp4$/i', $res); print_r($res);

see ideone demo

if there no semi-colons, glued:

// no semi_colons $str='get........ref=mp4get........ref=flvget........ref=mp4'; preg_match_all('/get\b(?:(?!get\b).)*mp4(?=$|get\b)/', $str, $res); print_r($res);

javascript - Why does running this loop 9 times take 100x longer than running it 8 times? -

consider code: test = function() { } t = new test(); (var = 0; < 8; i++) { result = t instanceof test; } if change number of iterations 8 9 , loop take 100 times longer complete in latest version of firefox (41.0.1). tested on 2 different pcs , magic limit 8. here jsperf test used: http://jsperf.com/instanceof-8-times-vs-9-times does have idea why might happen? seems specific instanceof . not happen if else object, example check property. note: filed bugzilla bug this. jan de mooij mozilla team has posted details in bugzilla thread . here's simplistic interpretation of highly technical answers: in i < 8 case, firefox smart enough hoist result = t instanceof test; statement out of loop (according tests, doesn't seem omit altogether). in i < 9 case, apparently doesn't optimization . why? reason not clear, related fact 9 iterations threshold above function considered "hot" enough run through jit compiler. i < 8 cas...
