This is a very bare (really just 20 lines of code, comments included) yet very thoroughly tested (100% MSI) programmatic source code linter. Give it a piece of source code from a file or as a string, and it will tell you if this is a valid PHP or not. But do not forget to include the opening <?php
tag.
The linter uses the default PHP executable found in PATH
. If you want to test your code with a different, non-default, PHP executable, consider other libraries out there, careful PATH
manipulation, or, provided you have a convincing argument, you can send a pull request.
composer require sanmai/linter
$linter = new \Linter\StringLinter('<?php return 1;');
$result = $linter->foundErrors();
var_dump($result);
// bool(false)
$linter = new \Linter\StringLinter('<?php obviously invalid PHP code;');
$result = $linter->foundErrors();
var_dump($result);
// bool(true)
That's it!
