GIT tag and retag

Working with GIT allows tagging specific points along the repository that have some importance. Commonly, tag is used when a version is released. Here are examples of listing tags, adding and deleting a tag.

List tags

List tag on local

git tag -l "v1.*"

git tag

List tag on repository

git ls-remote --tags

Display details of a tag

git show v1.0.2

Add tag to current branch

git tag -a v1.0.2 HEAD -m "Update for version 1.0.2"

git push origin --tags

Tag can be added to a specific commit.

git tag -a v1.0.2 f8c3501-m "Update for version 1.0.2" 

Retagging

This requires deleting current tag, then publish changes to remote repository.

git tag -d v1.0.2

git push origin :refs/tags/v1.0.2

How to create a dynamic object from standard class

 PHP provides a class to create a temporary object where no specific class and members are required.

The class stdClass is the empty class in PHP used to cast other types to object. Among the example of stdClass usage;

1. Directly access the members by calling them
2. Dynamic objects can be provided for temporary usage

E.g. 

An array can be treated as an object by using stdClass. 

$tmpStudent = array(

"name" => "John Doe"

);

To access data, 

$tmpStudent['name']

$tmpStudent = new stdClass;

$tmpStudent->name = "John Doe";

Using the stdClass, this can be done as an object

$tmpStudent->name
