fgetcsv — Gets line from file pointer and parse for CSV fields
$stream,$length = null,$separator = ",",$enclosure = "\"",$escape = "\\"Similar to fgets() except that fgetcsv() parses the line it reads for fields in CSV format and returns an array containing the fields read.
Note: The locale settings are taken into account by this function. For example, data encoded in certain one-byte encodings may be parsed incorrectly if
LC_CTYPEisen_US.UTF-8.
streamA valid file pointer to a file successfully opened by fopen(), popen(), or fsockopen().
length
Must be greater than the longest line (in characters) to be found in
the CSV file (allowing for trailing line-end characters). Otherwise the
line is split in chunks of length characters,
unless the split would occur inside an enclosure.
Omitting this parameter (or setting it to 0,
or null in PHP 8.0.0 or later) the maximum line length is not limited,
which is slightly slower.
separator
The separator parameter sets the field separator.
It must be a single byte character.
enclosure
The enclosure parameter sets the field enclosure character.
It must be a single byte character.
escape
The escape parameter sets the escape character.
It must be a single byte character or the empty string.
The empty string ("") disables the proprietary escape mechanism.
Note: Usually an
enclosurecharacter is escaped inside a field by doubling it; however, theescapecharacter can be used as an alternative. So for the default parameter values""and\"have the same meaning. Other than allowing to escape theenclosurecharacter theescapecharacter 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.
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 on success, or false on failure.
Note:
A blank line in a CSV file will be returned as an array comprising a single null field, and will not be treated as an error.
Note: If PHP is not properly recognizing the line endings when reading files either on or created by a Macintosh computer, enabling the auto_detect_line_endings run-time configuration option may help resolve the problem.
Throws a ValueError if
separator or enclosure
is not one byte long.
Throws a ValueError if
escape is not one byte long or the empty string.
| Version | Description |
|---|---|
| 8.4.0 |
Relying on the default value of escape is now
deprecated.
|
| 8.3.0 | An empty string is returned instead of a string with a single null byte for the last field if it contains only an unterminated enclosure. |
| 8.0.0 |
length is now nullable.
|
| 7.4.0 |
The escape parameter now also accepts an empty
string to disable the proprietary escape mechanism.

Example #1 Read and print the entire contents of a CSV file
<?php
$row = 1;
if (($handle = fopen("test.csv", "r")) !== FALSE) {
while (($data = fgetcsv($handle, 1000, ",")) !== FALSE) {
$num = count($data);
echo "<p> $num fields in line $row: <br /></p>\n";
$row++;
for ($c=0; $c < $num; $c++) {
echo $data[$c] . "<br />\n";
}
}
fclose($handle);
}
?>
