I had similar issue. In my case it helped to have Yarn installed and first execute the command

***yarn***

and then execute the command

***yarn start***

That could work for you too if the project that you cloned have the yarn.lock file. Hope it helps!

This is how I did it and it seems to work pretty well.

In you webpack.config.js file add the following:

***devServer: {
inline:true,
port: 8008
},***
Obviously you can use any port that is not conflicting with another. I mention the conflict issue only because I spent about 4 hrs. fighting an issue only to discover that my services were running on the same port.

***componentWillReceiveProps(nextProps) {
// You don't have to do this check first, but it can help prevent an unneeded render
if (nextProps.startTime !== this.state.startTime) {
this.setState({ startTime: nextProps.startTime });
}
}***

I wrote this simple code that is testing localStorage size in bytes.
***const check = bytes => {
try {
localStorage.clear();
localStorage.setItem('a', '0'.repeat(bytes));
localStorage.clear();
return true;
} catch(e) {
localStorage.clear();
return false;
}
};***

When your height is not set (auto); you can give inner div some padding (top and bottom) to make it vertically center:

******

Use calc:

***.leftSide {
float: left;
width: 50px;
background-color: green;
}
.rightSide {
float: left;
width: calc(100% - 50px);
background-color: red;
}***
******

You can sometimes get this if you accidentally import/embed the same JavaScript file twice, worth checking in your resources tab of the inspector.

According to the docs, it's preferable to omit the closing tag if it's at the end of the file for the following reason:

If a file is pure PHP code, it is preferable to omit the PHP closing tag at the end of the file. This prevents accidental whitespace or new lines being added after the PHP closing tag, which may cause unwanted effects because PHP will start output buffering when there is no intention from the programmer to send any output at that point in the script.

If you are using Laravel Homestead, make sure you're calling the commands on the server.

***homestead ssh***
Then simply cd to the right directory and fire your command there.

PHP is a dynamic language, so you can't overload methods. You have to check the types of your argument like this:

***class Student
{
protected $id;
protected $name;
// etc.

public function __construct($idOrRow){
if(is_int($idOrRow))
{
$this->id = $idOrRow;
// other members are still uninitialized
}
else if(is_array($idOrRow))
{
$this->id = $idOrRow->id;
$this->name = $idOrRow->name;
// etc.
}
}***

If you cannot modify your php.ini configuration, you could as well use the following snippet at the beginning of your code:

***date_default_timezone_set('Africa/Lagos');//or change to whatever timezone you want***

The definition of PHP_EOL is that it gives you the newline character of the operating system you're working on.

In practice, you should almost never need this. Consider a few cases:

When you are outputting to the web, there really isn't any convention except that you should be consistent. Since most servers are Unixy, you'll want to use a "\n" anyway.

If you're outputting to a file, PHP_EOL might seem like a good idea. However, you can get a similar effect by having a literal newline inside your file, and this will help you out if you're trying to run some CRLF formatted files on Unix without clobbering existing newlines (as a guy with a dual-boot system, I can say that I prefer the latter behavior)

PHP_EOL is so ridiculously long that it's really not worth using it.
