问题 Yes I know array_unique function, but the thing is that match might have a legitimate duplicates in my search term for example: $str = "fruit1: banana, fruit2: orange, fruit3: banana, fruit4: apple, fruit5: banana"; preg_match("@fruit1: (?<fruit1>\w+), fruit2: orange, fruit3: (banana), fruit4: (?<fruit4>apple), fruit5: (banana)@",$str,$match); array_shift($match); // I dont need whole match print_r($match); output is: Array ( [fruit1] => banana [0] => banana [1] => banana [fruit4] => apple [2

问题 I'm trying to modify a line in PHP file that deals with data that comes from XML(about 600 stations). The php make this data usable by a streamer media player. The original line is this if (($title <> "")&& (strpos($link,"<") === false)&& preg_match("/Cha/i",$lang)) this gives me about 50 stations, I want to add few stations that do not have "Cha" in $lang but "Soprts" and has "China" in their $title. So I wrote the line like this if (($title <> "")&& (strpos($link,"<") === false)&& preg

问题 I would like to have your opinion on a simple regular expression I built to verify a list of comma separated file extensions (there could also be one or multiple spaces after or before the comma character).
