str_getcsv — Parse a CSV string into an array
$string
,$separator
= ",",$enclosure
= "\"",$escape
= "\\"Parses a string input for fields in CSV format and returns an array containing the fields read.
Nota:
The locale settings are taken into account by this function. If
LC_CTYPE
is e.g.en_US.UTF-8
, strings in one-byte encodings may be read wrongly by this function.
string
The string to parse.
separator
Set the field delimiter (one single-byte character only).
enclosure
Set the field enclosure character (one single-byte character only).
escape
Set the escape character (at most one single-byte character). Defaults as a backslash
(\
)
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.
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.

The escape parameter now interprets an empty
string as signal to disable the proprietary escape mechanism. Formerly,
an empty string was treated like the default parameter value.
