PHP JPEG support is not configured properly the problem under PHP 5.3.x
Aufgefallen ist mir diesem Problem beim Aufsetzten eines Magento Online-Shops, der nach einem Upgrade auf PHP 5.3.1 plötzlich keine PDFs mehr produzieren konnte. Statt dessen nu lapidar den Dienst mit folgender Fehlermeldung quittierte.
Undefined index: JPG Support in /usr/local/lib/php/Zend/Pdf/Resource/Image/Jpeg.php on line 60
Eine Befragung des Google-Orakels brachte dann auch schnell Linderung. Schuld ist wohl eine Änderung einens Strings der die API-Fähigkeiten beschreibt. So änderte sich “JPG” in “JPEG“, was dazu führt das das Zend Framework plötzlich der Meinung ist das das drunterliegende PHP nicht mehr richtig in der Lage ist JPG-Grafiken zu verarbeiten.
Im Bugtracker des Zendframeworks hat man auch gleich einen kleinen Patch parat (BUG ZF6715).

Wie man sehen kann ändern sich nur zwei Zeilen in der Datei Zend/Pdf/Resource/Image/Jpeg.php das kann man auch leicht mit einem einfachen Editor wie nano, vim oder mc manuell ausführen. Dazu in genannter Datei die Zeile 53 von
view source print ?
1 | if (!function_exists('gd_info')) { |
in
view source print ?
1 | if (!function_exists('gd_info') || !function_exists('imagetypes')) { |
und Zeile 59 von
view source print ?
1 | if (!$gd_options['JPG Support'] ) { |
in
view source print ?
1 | if ((imagetypes() & IMG_JPG) == 0) { |
abändern fertig ! Nun sollte alles wieder wie gewohnt arbeiten.

JWT is an open standard based on JSON, used to securely transmit information between parties, mainly for identity authentication and information exchange. 1. JWT consists of three parts: Header, Payload and Signature. 2. The working principle of JWT includes three steps: generating JWT, verifying JWT and parsing Payload. 3. When using JWT for authentication in PHP, JWT can be generated and verified, and user role and permission information can be included in advanced usage. 4. Common errors include signature verification failure, token expiration, and payload oversized. Debugging skills include using debugging tools and logging. 5. Performance optimization and best practices include using appropriate signature algorithms, setting validity periods reasonably,

Session hijacking can be achieved through the following steps: 1. Obtain the session ID, 2. Use the session ID, 3. Keep the session active. The methods to prevent session hijacking in PHP include: 1. Use the session_regenerate_id() function to regenerate the session ID, 2. Store session data through the database, 3. Ensure that all session data is transmitted through HTTPS.

The application of SOLID principle in PHP development includes: 1. Single responsibility principle (SRP): Each class is responsible for only one function. 2. Open and close principle (OCP): Changes are achieved through extension rather than modification. 3. Lisch's Substitution Principle (LSP): Subclasses can replace base classes without affecting program accuracy. 4. Interface isolation principle (ISP): Use fine-grained interfaces to avoid dependencies and unused methods. 5. Dependency inversion principle (DIP): High and low-level modules rely on abstraction and are implemented through dependency injection.
