Installation precautions

Only with mac give an example

Look at the official documents , I used the following steps myself. Anyway, the installation failed

In the local mac Installing extensions on your PC , It didn't work . however , There's another way , Simple , Fast and effective .

My local address is laradock Environmental Science , If someone is like me , You can keep looking down

• 1. Direct editing laradock In the document env, And modify php-fpm And workspace To configure
  Such as ：
  .env file ：

### WORKSPACE #############################################
WORKSPACE_INSTALL_XLSWRITER=true

### PHP_FPM ###############################################
PHP_FPM_INSTALL_PHP_XLSWRITER=true

Insert a sentence here ： Why? workspace Also install
This is because when used xlswriter when , Use the locally configured domain name , Is take the laradock Containers , And the code is in workspace In the container , So if workspace This plug-in is not installed in the container , The code will still prompt that the plug-in does not exist

• 2. modify laradock The root directory docker-compose.yml file

### PHP-FPM ##############################################
    php-fpm:
      build:
        context: ./php-fpm
        args:
			- INSTALL_XLSWRITER=${
    PHP_FPM_INSTALL_PHP_XLSWRITER}

### Workspace Utilities ##################################
    workspace:
      build:
        context: ./workspace
        args:
        	- INSTALL_XLSWRITER=${
    WORKSPACE_INSTALL_XLSWRITER}

• 3. Modify the root directory php-fpm/Dockerfile and workspace/Dockerfile
  php-fpm/Dockerfile

#####################################
# xlswriter:
#####################################
USER root
ARG INSTALL_XLSWRITER=false
RUN if [ ${
    INSTALL_XLSWRITER} = true ]; then \
    pecl install xlswriter \
    && printf "extension=xlswriter.so\n" > $PHP_INI_DIR/conf.d/xlswriter.ini \
    && php -m | grep -q 'xlswriter' \
;fi

/workspace/Dockerfile

#####################################
# xlswriter:
#####################################
USER root
ARG INSTALL_XLSWRITER=false
RUN if [ ${
    INSTALL_XLSWRITER} = true ]; then \
    pecl install xlswriter \
    && printf "extension=xlswriter.so\n" > /etc/php/${
    LARADOCK_PHP_VERSION}/cli/conf.d/xlswriter.ini \
    && php -m | grep -q 'xlswriter' \
;fi

• 4. After saving successfully , recompile ,docker-compose build php-fpm And docker-compose build workspace
• 5. Into the container , perform php -m command , Check if the plug-in is installed successfully

composer require viest/php-ext-xlswriter-ide-helper:dev-master

Generate fileObject

pubic function generateFileObject(){
    
  $config = ['path' => config('*.*.path')];
   $excel = new \Vtiful\Kernel\Excel($config);
   return $excel->constMemory($this->fileName);
}

addStyle

private function addStyle(Object $fileObject){
    
  $fileHandle = $fileObject->getHandle();

  $format = new \Vtiful\Kernel\Format($fileHandle);
  // Combination style , font size , The font color , The background color , bold 
  $boldColorStyle = $format->bold()->fontSize(14)->fontColor(\Vtiful\Kernel\Format::COLOR_ORANGE)
  ->align(\Vtiful\Kernel\Format::FORMAT_ALIGN_VERTICAL_CENTER)
  ->align(\Vtiful\Kernel\Format::FORMAT_ALIGN_CENTER)->toResource();

  return $fileObject->setRow('A1',30, $boldColorStyle)
  ->header($this->header)
  ->gridline(\Vtiful\Kernel\Excel::GRIDLINES_SHOW_ALL);
}

use

$fileObject = $this->generateFileObject();
$fileObject = $this->addStyle($fileObject);
$fileObject->data($data);
$fileObject->output();
