what necessity guid attribute? why don't let compiler handle automatically?! if compiler handled automatically, you'd end 1 of 2 situations. a new guid every time compiled - since guids supposed published, fail. collisions - if guid same every time, based on (say) hash of name, multiple projects end using same guid different purposes. the existing approach - explicit guid gives developers power control these required.

this first time using curl might silly error on part following code: $ch = curl_init($url); curl_setopt($ch, curlopt_returntransfer, 1); $output = curl_exec($ch); curl_close($ch); echo $output; prints "1". understanding curlopt_returntransfer should ensure curl_exec returns either 0 or content here it's behaving if curlopt_returntransfer hasn't been set true. missing obvious? thanks! i'd use guzzle , oop wrapper around curl. (though since you're using request, file_get_contents($url); work fine). there's no real issue code, though. sure url valid? also, check make sure curl_setopt returning true each call it, , try setting curlopt_url using function.

now bitbucket supports git repositories, seams me alternative github , since free plan includes unlimited private repositories, not available on github. yet, github seams more popular. are there major reasons choose github hosting site git repositories instead of bitbucket? (although have no problems making personal projects publicly available in general, idea of being able make switch public private or vice versa time want. if there reasons use github, willing give freedom.) this should community wiki, since it's subjective think of use community. github's greatest strength it's in use, , supported more 3rd parties. example, continuous integration services travis ci or buildhive feature transparent integration github. personally, use github public code because it's pretty used , supported , use codeplane private code, because $9 month unlimited repos pretty good.
