A Abbas author When dealing with Arabic text in databases, we face the problem of different letter shapes due to hamzas and diacritics. To solve this problem, we need to ignoring these differences. Proposed solution using regular expressions in PHP to convert all the shapes of a single letter into one unified shape before performing the comparison process. Here is an example explaining the idea in PHP: function search($searchTerm) { // Converting the search to a uniform form to ignore hamzas and Ta Marbuta $searchTerm = preg_replace('/[\u0621\u0623\u0625\u0627]/u', 'ا', $searchTerm); // [ا أ إ آ] $searchTerm = preg_replace('/[\u0647\u0649]/u', 'ه', $searchTerm); // [ة ه] $searchTerm = preg_replace('/[\u0649\u064A\u0626]/u', 'ى', $searchTerm); // [ى ي ئ] // SQL query to search database (example using PDO) $pdo = new PDO("mysql:host=localhost;dbname=mydatabase", "username", "password"); $stmt = $pdo->prepare("SELECT * FROM users WHERE name LIKE :searchTerm"); $searchTerm = '%' . $searchTerm . '%'; // Partial search $stmt->bindParam(':searchTerm', $searchTerm); $stmt->execute(); $results = $stmt->fetchAll(PDO::FETCH_ASSOC); return $results; } Question: How can this idea be applied to research in PHPRunner?

	Not knowing of what quality the following Copilot (AI-generated code) answer is all about to fit your needs it is my understanding that it a general purpose script to remove diacritics..., so, it is just meant to be an inspiration ... quote It looks like you’re interested in handling diacritics, specifically Hamza, in PHP code. Hamza is a diacritic in Arabic script that represents a glottal stop. There are two main types: Hamzat al-Wasl and Hamzat al-Qat12. To handle diacritics in PHP, you can use the mbstring extension, which provides multibyte string functions. Here’s a simple example of how you might handle Arabic text with diacritics: PHP <?php // Ensure the mbstring extension is enabled mb_internal_encoding("UTF-8"); // Example Arabic string with Hamza $arabicString = "أحمد"; // Normalize the string to remove diacritics $normalizedString = preg_replace('/\p{Mn}/u', '', $arabicString); echo $normalizedString; // Outputs: احمد ?> AI-generated code. Review and use carefully. More info on FAQ. In this example, preg_replace is used with a regular expression to remove diacritic marks from the string. The \p{Mn} pattern matches all non-spacing marks, which include diacritics. If you have more specific requirements or need further assistance, feel free to ask!
