PHP – swap two variable values

~ tadmin

For example, you have a function which takes two parameters int|float $min and int|float $max parameters and you need to swap variable values vise versa, in case if $max value is less then $min value.

You can do it using the following code below:

if ($min > $max) {
    list($min, $max) = [$max, $min];
}

Git – copy few branches from old repository to a new one

~ tadmin

Sometimes, then you need to transfer few Git branches from existing repository to a new one you could run the following commands:

git clone --no-checkout [New Git Repository URL] new-repo-folder

This command will create a new folder new-repo-folder with a .git folder inside, but without any files from branches.

Change to the repository folder:

cd new-repo-folder

Adding the necessary branches: Now you need to do “remote tracking” for the desired branches. You could do it using commands below:

git remote add old-origin [Original Git Repository URL]

git fetch old-origin dev:dev
git fetch old-origin stage:stage
git fetch old-origin prod:prod

This will add the dev, stage, and prod branches from the original repository to your local copy.

Check: Verify that you now have only these three branches.

git branch -l

In case if you have also have copied Git tags use the command below:

git tag -l

to list all Git tags.

To remove all local tags use the command below:

git tag -l | xargs git tag -d

To push all branches to remote use the following command:

git push origin --all

Bulk files rename shell script for Linux

~ tadmin

If you need to make a bulk files rename on Linux you could use the following Bash Shell script:

#!/bin/bash

# Specify the directory where the files are located
directory="/home/user/Videos/2023-08-18"

# Change to the directory
cd "$directory"

# Iterate over the files matching the pattern and rename them
for file in [0-9]*.mp4; do
    new_filename=$(echo "$file" | sed -E "s/^([0-9]+)\.mp4$/_name-prefix-\1.mp4/")
    mv -v "$file" "$new_filename"
done

Just replace directory variable value to an actual path to folder with *.mp4 files on your system.

Replace _name-prefix- with a desired file names prefix.

You could use the following Gist: with bulk mp4 files rename shell script.

Generate .htaccess config file using tee shell command

~ tadmin

If you are using Docker setup for Yii2 Advanced application template to build REST API as I do, you could be interested in the command below:

tee /app/api/web/.htaccess <<EOF
RewriteEngine on

RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d

RewriteRule . index.php
EOF

it is generating .htaccess configuration file for Apache web server to redirect all requests from not existing files or directories to index.php file in API web application inside Docker container.

Multiple lines below starting < and closing EOF are the configuration file content. Such multiple lines syntax is called heredoc. You could choose any other identifier (one word in upper case letters) instead of EOF if you want.

Web server Apache Mod_rewrite module should be installed and enabled to make it work.

Docker network declared as external could not be found

~ tadmin

I’ve faced the following error running CoreShop 3.0.2 demo in a Docker running command:

docker-compose up -d

I’ve got the following error:

network cors_dev declared as external, but could not be found

To fix it run the commands below:

docker network create "cors_dev"
docker-compose up -d

I hope this will save several minutes of your time.
