** Aumentar longitud del de la función fgetcsv()

[David]

Según el manual:

Must be greater than the longest line (in characters) to be found in the CSV file (allowing for trailing line-end characters). It became optional in PHP 5. Omitting this parameter (or setting it to 0 in PHP 5.0.4 and later) the maximum line length is not limited, which is slightly slower.
