Composer can be learned through the following address: Learning address

Modification of wp-config.php file has always been a challenge in managing WordPress websites. This is not only because the file content is complicated, but also because a little carelessness in manual modification may cause the website to crash. Once, I tried to edit this file manually, but because of a small syntax error, the entire website was paralyzed and it took a lot of time and effort to fix it.

In this case, I started looking for a safer and more efficient solution and finally found the wp-cli/wp-config-transformer tool. This tool can help us programmatically edit wp-config.php file to avoid the risk of manual operations.

Installing wp-cli/wp-config-transformer with Composer is very simple, just run the following command in the terminal:

 <code>composer require wp-cli/wp-config-transformer</code>

After the installation is complete, we can use the following code to instantiate WPConfigTransformer class:

 <code class="php">$config_transformer = new WPConfigTransformer('/path/to/wp-config.php');</code>

Next, we can use this tool to edit constants and variables. For example, update WP_DEBUG constant:

 <code class="php">$config_transformer->update('constant', 'WP_DEBUG', 'true', array('raw' => true));</code>

Add a new constant:

 <code class="php">$config_transformer->add('constant', 'MY_SPECIAL_CONFIG', 'foo');</code>

Or remove a constant:

 <code class="php">$config_transformer->remove('constant', 'MY_SPECIAL_CONFIG');</code>

The same method can also be used for variables:

 <code class="php">$config_transformer->update('variable', 'table_prefix', 'wp_custom_'); $config_transformer->add('variable', 'my_special_global', 'foo'); $config_transformer->remove('variable', 'my_special_global');</code>

In addition, we can check whether a configuration exists:

 <code class="php">if ($config_transformer->exists('constant', 'MY_SPECIAL_CONFIG')) { // 執(zhí)行相關操作} if ($config_transformer->exists('variable', 'my_special_global')) { // 執(zhí)行相關操作}</code>

wp-cli/wp-config-transformer provides some special options to control the addition and update behavior of configurations. For example, the output can be normalized by the normalize option to comply with WordPress encoding standards:

 <code class="php">$config_transformer->update('constant', 'WP_DEBUG', 'true', array('raw' => true, 'normalize' => true));</code>

Use the raw option to insert unreferenced code directly:

 <code class="php">$config_transformer->update('constant', 'ABSPATH', "dirname(__FILE__) . '/somewhere/else/'", array('raw' => true));</code>

With anchor , placement and separator options, we can control the insertion position and format of the new configuration:

 <code class="php">$config_transformer->update('constant', 'FOO', 'bar', array('anchor' => '/** Absolute path to the WordPress directory')); $config_transformer->update('constant', 'BAZ', 'qux', array('placement' => 'after')); $config_transformer->update('constant', 'FOO', 'bar', array('separator' => PHP_EOL . PHP_EOL));</code>

If the configuration does not exist, you can use the add option to decide whether to add a new configuration:

 <code class="php">$config_transformer->update('constant', 'FOO', 'bar', array('add' => true)); // 默認行為$config_transformer->update('constant', 'FOO', 'bar', array('add' => false));</code>

Using wp-cli/wp-config-transformer not only greatly reduces the risk of manually editing wp-config.php files, but also provides flexible configuration options to make configuration management more efficient and controllable.

In general, wp-cli/wp-config-transformer greatly simplifies the modification process of WordPress configuration files through the installation and use of Composer, and improves the security and efficiency of website management. If you often need to modify WordPress configuration files, you might as well try this tool.
