>From the manual - may be what you want:
fgetcsv (PHP 3>= 3.0.8, PHP 4 >= 4.0.0)
Gets line from file pointer and parse for CSV fields
array fgetcsv (int fp, int length, string [delimiter])
Similar to fgets() except that fgetcsv() parses the line it reads for
fields in CSV format and returns an array containing the fields read. The
field delimiter is a comma, unless you specify another delimiter with the
optional third parameter.
Fp must be a valid file pointer to a file successfully opened by fopen(),
popen(), or fsockopen()
Length must be greater than the longest line to be found in the CSV file
(allowing for trailing line-end characters).
fgetcsv() returns FALSE on error, including end of file.
N.B. 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.
Example 1. fgetcsv() example - Read and print entire contents of a CSV
file
$row = 1;
$fp = fopen ("test.csv","r");
while ($data = fgetcsv ($fp, 1000, ",")) {
$num = count ($data);
print " $num fields in line $row: ";
$row++;
for ($c=0; $c<$num; $c++) {
print $data[$c] . "";
}
}
fclose ($fp);

Re: [PHP] Parsing a CSV file
Re: [PHP] Parsing a CSV file there is no need to special-case here, for empty statements would also be handled by repeated calls to explode (). quoted expressions can be joined by preg_matches then.

RE: [PHP] Parsing a CSV file
That won't do if the list is 'R001,23,"2,5"'.
I'd break that to parts with preg_match_all().

sure. explode (',', $yourdata) is what you are looking for. use file ()
to read in the file and use foreach () to iterate over the lines.
