During WordPress development, you often encounter situations where you need to quickly execute some PHP code. For example, you may need to temporarily test a function without modifying the core WordPress file, or you may need to debug the code execution in a specific scenario. Faced with this need, traditional methods may involve manually editing files or using complex debugging tools, which is not only time-consuming and labor-intensive, but also error-prone.
Fortunately, the eval-command feature of WP-CLI provides us with a more convenient and efficient solution. This command line tool allows you to execute arbitrary PHP code directly from the command line or load and execute PHP files without modifying any existing files. This not only greatly improves development efficiency, but also reduces the risk of possible introduction of errors.
Installing WP-CLI and eval-command using Composer is very simple, just run the following command:
<code>wp package install git@github.com:wp-cli/eval-command.git</code>
This way, you can use eval-command directly through WP-CLI. Let's look at some examples of usage:
Execute PHP code using wp eval
wp eval
allows you to execute PHP code directly from the command line. For example, to print the WordPress content directory path, you can do this:
<code>wp eval 'echo WP_CONTENT_DIR;'</code>
If you need to generate a random number and do not need to load WordPress, you can use --skip-wordpress
parameter:
<code>wp eval 'echo rand();' --skip-wordpress</code>
Load and execute PHP files using wp eval-file
If you have a more complex piece of PHP code, you can save it as a file and then load and execute it using wp eval-file
. For example:
<code>wp eval-file path/to/your-script.php</code>
If you want to read the code from standard input, you can use -
as file path:
<code>echo "echo 'Hello, World!';" | wp eval-file -</code>
If you need to pass parameters to the script, you can do this:
<code>wp eval-file path/to/your-script.php arg1 arg2</code>
In the script, you can access these parameters through the $args
variable.
Practical application effect
I greatly improved efficiency during development by using the convenient installation of eval-command and Composer of WP-CLI. Whether it is to quickly test the code or debug problems without affecting the production environment, eval-command provides great convenience. At the same time, Composer's package management capabilities make installing and updating these tools simple and reliable.
In general, WP-CLI's eval-command combines the power of Composer to provide WordPress developers with an efficient, secure and convenient code execution solution. If you often need to temporarily execute PHP code during development, this tool combination will be an indispensable helper for you.
