Bonjour,

Je suis artisan et je bricole le php en amateur depuis quelques années. Pour joindre l'utile à l'agréable, j'ai fait un script (basé sur un que j'ai trouvé) qui me permet de récupérer les factures PDF de mes fournisseurs en pièce jointe depuis ma boite mail, puis de les parser.
Cela marche pour la quasi-totalité de mes factures à l'exception d'un fournisseur et cela m'embête bien.

Je précise que les mails de ce fournisseur sont générer automatiquement.

Lorsque je télécharge la pièce jointe manuellement depuis mon client de messagerie (Thunder birds), pas de problème le PDF peut être ouvert et parsé.

En revanche le PDF que je récupère depuis mon script est mauvais.


Voici les messages d'erreur que j'ai :

En affichant le PDF dans vsCode :

PDF.js v2.10.377 (identifiant de compilation : 156762c48)
Message : Invalid PDF structure.

En ouvrant le PDF avec Acrobat :

Nom : temps.jpg Affichages : 209 Taille : 50,4 Ko

J'ai l'impression que cela viens du décodage

Voici le script :

Auriez vous une idée de la raison pour laquelle mon ficher est invalide ?

Je vous remercie
