Verifica immagine
Salve a tutti, ho trovato su internet questo script per riconosce da link se un file č un immagine:
Codice PHP:
if(strlen($testo_form_photo) > 0)
{
$FilePointer = fopen($testo_form_photo, "r");
if($FilePointer)
{
$FileHeaders = stream_get_meta_data($FilePointer);
foreach($FileHeaders as $FileHeader)
{
foreach($FileHeader as $HeaderValue)
{
if(strpos(strtolower($HeaderValue), "image/jpg"))
{echo "ok";}
}
}
}
}
Se perņ provo ad usarlo ricevo una lunga serie di errori:

Ho notato che $FilePointer contiene "Resource id #30", sapete quale possa essere il problema?
