Just watched first composer video. As someone who kept looking at composer and having it fly right over their head a few times, this was really good. It actually went to the necessary level of detail instead of assuming users having familiarity with miscellaneous subtle details that are often left out.

Thank you Reval! I have looked for DAYS for an example of what it actually looks like to install a package using Composer, seeing what is going on. This embodies the detail of the relationship between the local server, composer, what the hierarchy looks like after it's installed, WHERE to install it in the first place! THANK YOU. Excellent work!! You kept it to a bare-bones example that provides such valuable clarity for a newbie. Thoughtful presentation, greatly greatly appreciated!!! You a-b-s-o-l-u-t-e-l-y ROCK!

Need lesson/tip on using composer for an old project. I faced a lot of issues with composer if the project/website is old and need to install a new plugin. Dependencies never seems to met and it makes impossible to add new plugin. Sometimes old plugins aren't available anymore and I am forced to use newer ones for which I have no idea how to make sure to get right packages and update the older ones.

i got composer installed on my local pc but how can i use it to update my website on a host server? how can i access ftp directory with it?

I need to do this by using PHP and composer and this is the task, so what does this mean and how am I suppose to do it?
Sorry I never programmed in PHP or used Composer before, Can u help?

*The task
[The aim is is implement the source code link to pass the pre written tests.

To run the tests run ./vendor/bin/phpunit and look at the output.

The toInt function should be able to translate any Roman Numerial to the correct integer.

For example VI should return 6 and XX should return 20

Cant get phpunit running ?
Included is an index file (index.php) This should run on any web server (eg MAMP, XAMP etc)]

*and this is what the source code looks like!

<?php
namespace PhpNwSykes;

class RomanNumeral
{
protected $symbols = [
1000 => 'M',
500 => 'D',
100 => 'C',
50 => 'L',
10 => 'X',
5 => 'V',
1 => 'I',
];

protected $numeral;

public function __construct(string $romanNumeral)
{
$this->numeral = $romanNumeral;
}

/**
* Converts a roman numeral such as 'X' to a number, 10
*
* @throws InvalidNumeral on failure (when a numeral is invalid)
*/
public function toInt():int
{
$total = 0;

return $total;
}
}

and this is the link to the actual exercise if you want to see for yourself! :0


and this is the link to that actual source code! :0

I have downloaded composer for the purposes of reading xlsx files. I have watched a couple of tutorials to enable me to use the data within a mysql database.


I have composer installed and ready to go but cannot get any further. Do you have, or are you considering doing a tutorial on reading from an xlsx file? Thanks

[csandreas]

if you want to update the library you perform the same procedure?

[mazoody]

The perfect tutorial for composer. Good work.

Hi! Where did you write the command which you copy from packagist??
Thanks

[kensleylewis]

this feels a lot like npm for javascript projects. so where can learn more about packages available through composer?

[commanderbensisko]

Doesn't the presence of the package in the lock file mean it was previously installed?

[TheGarageboyz]

got localhost is currently unable to handle this request.

I've got a shared hosting service for my website, so I don't have access to WHM and can't run commands like you did.
Can I still use composer?

[siddiquiquameruddin]

Can u please tell me command prompt name which you used

[Viperdwarrior]

It's always easy to pull package for a new project but way too hard for adding one with old and existing projects
