SplFileObject::fgetcsv — Gets line from file and parse as CSV fields
$separator
= ",", string $enclosure
= "\"", string $escape
= "\\"): array|falseGets a line from the file which is in CSV format and returns an array containing the fields read.
Nota: Le impostazioni locali vengono prese in considerazione da questa funzione. Ad esempio, i dati codificati in determinati formati a byte singolo potrebbero essere analizzati in modo errato se
LC_CTYPE
è impostato suen_US.UTF-8
.
separator
The field delimiter (one single-byte character only).
By default ,
or the value set by a prior call to
SplFileObject::setCsvControl().
enclosure
The field enclosure character (one single-byte character only).
By default "
or the value set by a prior call to
SplFileObject::setCsvControl().
escape
The escape character (at most one single-byte character).
By default \
or the value set by a prior call to
SplFileObject::setCsvControl().
An empty string (""
) disables the proprietary escape mechanism.
Nota: Usually an
enclosure
character is escaped inside a field by doubling it; however, theescape
character can be used as an alternative. So for the default parameter values""
and\"
have the same meaning. Other than allowing to escape theenclosure
character theescape
character has no special meaning; it isn't even meant to escape itself.
As of PHP 8.4.0, depending on the default value of
escape
is deprecated.
It needs to be provided explicitly either positionally or by the use
of Named Arguments,
or by a call to SplFileObject::setCsvControl().
When escape
is set to anything other than an empty string
(""
) it can result in CSV that is not compliant with
» RFC 4180 or unable to survive a roundtrip
through the PHP CSV functions. The default for escape
is
"\\"
so it is recommended to set it to the empty string explicitly.
The default value will change in a future version of PHP, no earlier than PHP 9.0.
Returns an indexed array containing the fields read, or false
on error.
Nota:
A blank line in a CSV file will be returned as an array comprising a single
null
field unless usingSplFileObject::SKIP_EMPTY | SplFileObject::DROP_NEW_LINE
, in which case empty lines are skipped.
Genera un ValueError se
separator
o enclosure
non sono lunghi un byte.
Genera un ValueError se
escape
non è lungo un byte o è una stringa vuota.

<?php
$file = new SplFileObject("data.csv");
while (!$file->eof()) {
var_dump($file->fgetcsv());

example
<?php
$file = new SplFileObject("animals.csv");

foreach ($file as $row) {
list($animal, $class, $legs) = $row;
printf("A %s is a %s with %d legs\n", $animal, $class, $legs);
}
?>
