regex - Use PHP to extract specific string data -


the iframe assigned variable $string. want extract texts between embed/ , ?rel in iframes src. looking code sl-2oyai35o

<iframe width="420" height="315" src="http://www.youtube.com/embed/sl-2oyai35o?rel=0" frameborder="0" allowfullscreen></iframe>

would need use php substr function or regex? cant use regular substring because start value may differ.

$text = '<iframe width="420" height="315" src="http://www.youtube.com/embed/sl-2oyai35o?rel=0" frameborder="0" allowfullscreen></iframe>';  preg_match('`embed/(.+)\?rel`i', $text, $matches); $code = (!empty($matches[1])) ? $matches[1] : '';

i have database in store data based upon following 3 fields: id, text, {labels}. note each text has been assigned more 1 label \ tag \ class. want build model (weka \ rapidminer \ mahout) able recommend \ classify bunch of labels \ tags \ classes given text. i have heard svm , naive bayes classifier, not sure whether support multi-label classification or not. guides me right direction more welcome! the basic multilabel classification method one-vs.-the-rest (ovr), called binary relevance (br). basic idea take off-the-shelf binary classifier, such naive bayes or svm, create k instances of solve k independent classification problems. in python-like pseudocode: for each class k: learner = svm(settings) # example labels = [class_of(x) == k x in samples] learner.learn(samples, labels) then @ prediction time, run each of binary classifiers on sample , collect labels predict positive. (both training , prediction can done in parallel, since problems assumed ...
