Rinominare file

[Mister]

Sono alla prime armi,

avendo una form con diversi campi: nome, cognome e upload allegato, è possibile che il file in upload venga rinominato con i risultati dei campi nome e cognome?

ES: nome_cognome_fileallegato.pdf?

Sotto la parte di codice dell'upload.

Grazie.

esiste una funziona apposta in php e si chiama rename() quindi

rename('path/nome_file', 'path/$nome_$cognome');
