Summary: str_getcsv parses lines incorrectly
Status: Open
Type: Bug
Package: Unknown/Other Function

It is not about input validation :) Your example is clearly invalid input. The
function should fail and return FALSE. My example perfectly fits into formal
CSV
grammar, thus it is valid input. It is just parsed incorrectly.
I would not send you a bug about invalid input :)

str_getcsv is a conversion tool and not an input validator. Any invalid input
is
surely not going to work correctly and I do not think it is good practice to
account for bad input b/c it would cause extra processing time when it is not
needed.
If the input were:
var_dump(str_getcsv('"123" a , "456" ', ',', '"'))
what would you expect str_getcsv to do?

Description:
------------
Putting a space around the separator *and* using quotes around fields adds
spaces to the field. The following line:
"123" , "456"
should produce:
"123" and "456"
but it makes:
"123 " and " 456".
In the RFC4180 the specification suggests that if the field contains quotes,
only the text inside quotes is the content of the field. Here is the formal
gramma:
record = field *(COMMA field)
field = (escaped / non-escaped)
escaped = DQUOTE *(TEXTDATA / COMMA / CR / LF / 2DQUOTE) DQUOTE
non-escaped = *TEXTDATA
Thus spaces should appear in field only if the field is not quoted.
Test script:
---------------
print_r(str_getcsv('"123" , "456" ', ',', '"'))
Expected result:
----------------
array(
0 => "123",
1 => "456",
)
Actual result:
--------------
array(
0 => "123 ",
1 => "456 ",
)
