How to check PHP syntax using the command line

If you're using PHP for web developoment, you may often want to check the syntax of your file without opening it in a browser. Checking syntax is quite easy from the command line.


If you're on a Mac you can open Terminal which is located in: Applications/Utilities


You can navigate to your project folder by using the change directory or cd command followed by the directory. For me it is: cd /Users/josephtylerjones/Developer/scripts/


Now you can check the syntax of your script by running php -l followed by the file name. For me it is: php -l testfile.php This command will detect any syntax errors in your script!
