SplFileObject::fputcsv — Write a field array as a CSV line
$fields,$separator = ",",$enclosure = "\"",$escape = "\\",$eol = "\n"
Writes the fields array to the file
as a CSV line.
fieldsAn array of values.
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.
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,
or by a call to SplFileObject::setCsvControl().
eol
The optional eol parameter sets
a custom End of Line sequence.
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.
Note:
If an
enclosurecharacter is contained in a field, it will be escaped by doubling it, unless it is immediately preceded by anescape.
Returns the length of the written string or false on failure.
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.

Example #1 SplFileObject::fputcsv() example
<?php
$list = array (
array('aaa', 'bbb', 'ccc', 'dddd'),
array('123', '456', '789'),
array('"aaa"', '"bbb"')
);
$file = new SplFileObject('file.csv', 'w');
foreach ($list as $fields) {
$file->fputcsv($fields);
}
?>The above example will write the following to file.csv:
aaa,bbb,ccc,dddd 123,456,789 """aaa""","""bbb"""
