(PHP 4, PHP 5, PHP 7, PHP 8)

imagedestroyDestroy an image

Descrizione

imagedestroy(GdImage $image): bool

Nota:

This function has no effect. Prior to PHP 8.0.0, this function was used to close the resource.

Prior to PHP 8.0.0, imagedestroy() freed any memory associated with the image resource. As of 8.0.0, the GD extension uses objects instead of resources, and objects cannot be explicitly closed.

Elenco dei parametri

image

Una risorsa immagine, restituita da una delle funzioni di creazione immagine, come imagecreatetruecolor().

Valori restituiti

Restituisce true in caso di successo, false in caso di fallimento.

Versione Descrizione
8.0.0 This function is a NOP now.
