PHPExcel von ThinkPHP exportiert mehrere Bilddaten

Ich habe kürzlich Daten zum Exportieren von Bilddaten erstellt. Ich bin auf ein solches Projekt gestoßen und hoffe, es hiermit ein wenig zu inspirieren für Freunde in Not! ： Die Back-End-Controller-Methode: 控

Der Code wird geteilt. Diesmal muss der Code für den Erfolg in meinem Projekt geklärt werden Die Kernkategorie der PHPExcel-Datei ist der Schlüssel zum kostenlosen Download:

ThinkPHP implementiert die PHPExcel-Klassenbibliotheksdatei zum Exportieren von Daten in Excel-Dateien. Beachten Sie, dass Sie beim Exportieren mehrerer Bilder daran denken müssen, mehrere zu instanziieren Andernfalls kommt es zu Variablenkonflikten und Problemen beim Überschreiben von Bildern. Das letzte Problem besteht darin, dass beim Lesen von Datenbankdaten beurteilt werden muss, ob die Daten leer sind. Andernfalls tritt ein Programmfehler auf Ausnahmen, wenn diese beachtet werden, läuft unsere Funktion und stellt das Programm sehr gut dar.

Das obige ist der detaillierte Inhalt vonPHPExcel von ThinkPHP exportiert mehrere Bilddaten. Für weitere Informationen folgen Sie bitte anderen verwandten Artikeln auf der PHP chinesischen Website!
