PHP命令行执行脚本的几种方法

2. Run a PHP Script File

You can execute a standalone PHP file by passing its path to the php command. This is the most common way to run PHP applications via CLI.

• Create a file named test.php with content:
• In the terminal, navigate to the directory containing the file using cd.
• Run php test.php.
• The script output will be printed directly to the terminal.

3. Pass Arguments to PHP Scripts

PHP CLI allows passing arguments to scripts, which can be accessed via the $argv and $argc variables inside the script.

• Modify your test.php file to include:
• Execute it with arguments: php test.php arg1 arg2.
• The output will show an array of passed arguments including the script name.

4. Use Shebang for Direct Execution

On Unix-like systems, you can make a PHP script executable by adding a shebang line at the top and setting file permissions.

• Add #!/usr/bin/env php as the first line in your test.php file.
• Make it executable: chmod +x test.php.
• Run it directly: ./test.php.

This method treats the PHP script like a native shell script.

5. Check PHP Syntax Without Execution

Before running a script, you can validate its syntax using the -l (lint) option to prevent runtime errors.

• Run php -l test.php to check for parsing errors.
• If the syntax is correct, you'll receive a message confirming no syntax errors were detected.

This is especially helpful when debugging large scripts or deploying code.
