with function file_get_contents()

i html content of url.

i need in html find tag <source src="https://v.cdn.vine.co/r/videos/xxxxx.mp4 " type="video/mp4">

how source attribute src?

theres few ways this.

1. php dom - http://us1.php.net/dom

this doo-hickey make xml/xhtml object given source code supply. it's kind of tree structure can traverse through.

2. php xml - http://php.net/manual/en/book.xml.php

just #1 older xml parser.

3. string literal searching - http://php.net/manual/en/function.strpos.php

this oldey goody. use strpos() find source tag start, again find src tag , grab string. require tags perfect , doesn't leave lot of flexibility.

$source = strpos($html, '<source '); if($source!==false) {   $src_loc = strpos($html, 'src="', $source);   if($src_loc!==false) {     $end_quote = strpos($html, '"', $src_loc + 5);     if($end_quote!==false) {       $final_src = substr($html, $src_loc+5, $end_quote-($src_loc+5)); //tada!     }   } }

java - Copying object fields -

-
what best way of copying classes when need have 2 independent variables? have simple class: public class myclass { boolean = false; string b= "not empty"; } do need make method : assign(myclass data ) { a= data.a; b= data.b; } is there automatic method copy (duplicate) objects in java? do need make method : pretty close. instead of making method, should make constructor. such constructors called copy constructor , , create them this: myclass(myclass data) { = data.a; b = data.b; } and create copy of instance, use constructor this: myclass obj1 = new myclass(); myclass obj2 = new myclass(obj1); copy constructor can tedious : using copy constructor create deep-copy can tedious, when class has mutable fields. in case, assignment create copy of reference, , not object itself. have create copy of fields (if want deep copy). can go recursive. a better way create deep copy serialize , deserialize object. why not use clone()? ...

c++ - Clear the memory after returning a vector in a function -

-
i have function processes , stores lot of data in , returns results vector of class. amount of data stored in function tremendous , want clear storage memory of function after finished job. necessary (does function automatically clear memory) or should clear memory function? update: vector<customers> process(char* const *filename, vector<int> id) { vector<customers> list_of_customers; (perform actions) return list_of_customers; } variables defined locally within function automatically released @ end of function scope. destructors objects called, should free memory allocated objects (if objects coded correctly). example of such object std::vector . anything you've allocated new must have corresponding delete release storage. try avoid doing own allocation , use raii instead, i.e. containers or smart pointers.
