Sure, here's a bash script that will install the ImageMagick library and the imagick extension for PHP 7.4 by default, with an option for the user to choose PHP 8.3. This script will handle the installation through PECL and ensure the correct permissions are set for the library.

```bash
#!/bin/bash

# Function to install imagick for a specified PHP version
install_imagick() {
  PHP_VERSION=$1
  PHP_BIN="/usr/local/lsws/lsphp${PHP_VERSION}/bin"
  PHP_INI="/usr/local/lsws/lsphp${PHP_VERSION}/etc/php.ini"
  PHP_MODULES="/usr/local/lsws/lsphp${PHP_VERSION}/lib64/php/modules"

  echo "Installing ImageMagick development package..."
  dnf install -y ImageMagick-devel

  echo "Installing imagick extension for PHP ${PHP_VERSION}..."
  ${PHP_BIN}/pecl install imagick

  echo "Enabling imagick extension in php.ini..."
  echo "extension=imagick.so" >> ${PHP_INI}

  echo "Setting correct permissions for imagick.so..."
  chmod 755 ${PHP_MODULES}/imagick.so

  echo "Restarting lsws..."
  service lshttpd restart

  echo "Imagick extension installed and enabled for PHP ${PHP_VERSION}."
}

# Default PHP version
PHP_VERSION="74"

# Check for user input
if [ $# -eq 1 ]; then
  if [ $1 == "8.3" ]; then
    PHP_VERSION="83"
  elif [ $1 != "7.4" ]; then
    echo "Unsupported PHP version. Only 7.4 and 8.3 are supported."
    exit 1
  fi
fi

# Call the function to install imagick
install_imagick $PHP_VERSION
```

### Usage:
- Save the script to a file, for example, `install_imagick.sh`.
- Make the script executable: `chmod +x install_imagick.sh`.
- Run the script:
  - For PHP 7.4: `./install_imagick.sh`.
  - For PHP 8.3: `./install_imagick.sh 8.3`.

This script will check the provided PHP version and install the imagick extension for the corresponding version. If no version is specified, it defaults to PHP 7.4.
