Successor to PR #3523. There are 494 single-line changes (`public function provider` to `public static function provider`) in this PR. None of these were made manually; they were all created with the following script (adapted from https://stackoverflow.com/questions/25909820/how-to-recursively-iterate-through-files-in-php): ```php $dir = 'C:/git/unit10prep2/tests/PhpSpreadsheetTests'; $it = new RecursiveDirectoryIterator($dir); // Loop through files foreach(new RecursiveIteratorIterator($it) as $file) { if ($file->getExtension() === 'php') { $contents = file_get_contents($file); $new = preg_replace('/public function (\\w*)([Pp])rovider/', 'public static function $1$2rovider', $contents); if ($new !== $contents) { echo "changing $file\n"; file_put_contents($file, $new); } } } ``` After this PR, there will be one more, with a small number of test changes, and enabling PhpUnit 10 for Php 8.1+.
