Bonjour,

je suis nouveau sur le forum et souhaite faire exactement la meme chose que dans cette discussion : http://www.developpez.net/forums/d72...e-fichier-pdf/

Pour être précis, je souhaite trouver un script qui puisse extraire un code chiffré d'un PDF pour le renommer avec (entre autres) ce code isin.

Exemple :
le fichier "Reporting blablabla.pdf" contient le texte FR008129928 et je souhaite qu'il s'appelle après coup : 30122009_FR008129928_reporting.pdf

[s.n.a.f.u]

Il existe un soft qui s'appelle XPDF qui peut extraire du texte d'un pdf.

J'ai aussi trouvé ça, mais pas testé: http://community.livejournal.com/php/295413.html

Bonjour snafu,

merci de ton aide,
serais tu assez aimable pour copier dans le post l'information qui est sur la page que tu as mise en lien, car cette page est bloquée par le firewall de la boite.

merci a toi

Bonjour Fench,

merci pour ton aide,

Pardon pour la question de débutant en php, mais au vu du script,

je vois a peu près comment faire pour extraire la donnée..

mais

je ne vois pas où je peux intervenir sur le fait de renommer le fichier pdf, avec cette donnée extraite... (Je pense que c'est cette partie la plus difficile)

[Fench]

Tu as changé le Pdf en Txt,
Tu as récupéré ta donnée,

Reste plus qu'a renommer le fichier par les fonctions standarts non?
Attention aux droits sur les fichiers (voir chmod)
