Php – var_export to string

PHPrender-to-stringstring

I have an HTML code in the $output string, this code is delimited by two terms: -startMiniPreview- and -endMiniPreview-.
I need to take the part wrapped between those two terms and save it in another string variable.
This is what I thought was the right way to do so, but it's not working at all. The HTMLCODE part is getting exported succesfully but not as a string

    $output="-startMiniPreview-HTMLCODE-endMiniPreview-EXTRA";
    preg_match( '/\-startMiniPreview-(.*?)\-endMiniPreview/', $output,$vt);
    $cutOut=strval(var_export($vt[1]));

The documentation clearly gives the answer:

$cutOut = var_export($vt[1],true);

EDIT: That said, why are you doing this? Just $cutOut = $vt[1]; is all you need.

C# – the difference between String and string in C#

string is an alias in C# for System.String.
So technically, there is no difference. It's like int vs. System.Int32.

As far as guidelines, it's generally recommended to use string any time you're referring to an object.

e.g.

string place = "world";

Likewise, I think it's generally recommended to use String if you need to refer specifically to the class.

e.g.

string greet = String.Format("Hello {0}!", place);

This is the style that Microsoft tends to use in their examples.

It appears that the guidance in this area may have changed, as StyleCop now enforces the use of the C# specific aliases.

C++ – How to iterate over the words of a string

I use this to split string by a delimiter. The first puts the results in a pre-constructed vector, the second returns a new vector.

#include <string>
#include <sstream>
#include <vector>
#include <iterator>

template <typename Out>
void split(const std::string &s, char delim, Out result) {
    std::istringstream iss(s);
    std::string item;
    while (std::getline(iss, item, delim)) {
        *result++ = item;
    }
}

std::vector<std::string> split(const std::string &s, char delim) {
    std::vector<std::string> elems;
    split(s, delim, std::back_inserter(elems));
    return elems;
}

Note that this solution does not skip empty tokens, so the following will find 4 items, one of which is empty:

std::vector<std::string> x = split("one:two::three", ':');
