ID: 13950 Updated by: derick Reported By: liamr@umich.edu Old Status: Open Status: Bogus Old Bug Type: Documentation problem Bug Type: Filesystem function related Operating System: Sun (SPARC) Solaris 2.6 PHP Version: 4.0.6 / 4.20cvs New Comment: What output did you expect then from your example? Derick Previous Comments: ------------------------------------------------------------------------ [2001-11-08 16:32:16] jeroen@php.net The CSV format prescribes that fields may be enclosed in double quotes, to make it possible to have the delimiter itself part of a field. try google on CSV, to find a definition. If you find one, we'd appreciate it if you entered a link here, so we can make the documentation better. Changing to documentation bug (indeed, the docs aren't clear about this) ------------------------------------------------------------------------ [2001-11-08 16:22:46] liamr@umich.edu How is this /not/ a bug? It does the same thing indepentdent of delimiter. If I have a CSV file that looks like one,"two" three,four one,two" three",four one,two,three,four one,two "three" four,five and it gets read in as ('one', 'two', 'four') ('one',' two "three"', 'four') ('one', 'two', 'three', 'four') ('one', 'two "three" four', 'five') That behavoir does not match the function definition of fgetcsv in the manual. it is mishandling the data. "fgetcsv -- Gets line from file pointer and parse for CSV fields Description 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. " How can that possibly mean "strips off double quotes and removes subsequent data"? I'd expect it to split on the delimiter specified, and to file the resulting information into the array. ------------------------------------------------------------------------ [2001-11-08 15:33:14] jeroen@php.net This is exactly what fgetcsv is for (interpreting the double quotes in CSV files). Use explode if you simply want to split on tabs. No bug. --Jeroen ------------------------------------------------------------------------ [2001-11-08 14:34:20] liamr@umich.edu I tried it with the copy of PHP in CVS. It's a problem in that version too. ------------------------------------------------------------------------ [2001-11-06 00:23:31] liamr@umich.edu I'm trying to write a script to interpret pine-style addressbooks, which are pretty much just full tab-seperated values.. It doesn't handle fields with double quotes correctly. If the field starts with a quotes, it strips them, and removes any data that follows the closing quote for that field. This code and data will replicated the problem. <?php $row = 1; $fh = fopen("./addressbook","r"); while ($data = fgetcsv ($fh, 1000, "\t")) { $num = count($data); $match = preg_grep("/(#|\(|\))/", $data); if ( ($num < 3) || (count($match) >=1) ) { continue; } print "\n$num fields in line $row:\n"; $row++; for ($c=0; $c<$num; $c++) { print $data[$c] . "\n"; } } fclose ($fh); ?> "addressbook" is a tab separated file containing data along the lines of: liamr Hoekenga, Liam liamr@umich.edu liam "Liam Hoekenga" liam.hoekenga@umich.edu lhoek "Liam H." "Liam R. Hoekenga" <liamr@umich.edu> lrh ME "ME" ME liamr@umich.edu lrh1 "ME" ME liamr@umich.edu produces this output: 3 fields in line 1: liamr Hoekenga, Liam liamr@umich.edu 3 fields in line 2: liam Liam Hoekenga liam.hoekenga@umich.edu 3 fields in line 3: lhoek Liam H. Liam R. Hoekenga 3 fields in line 4: lrh ME "ME" ME liamr@umich.edu 3 fields in line 5: lrh1 ME liamr@umich.edu ------------------------------------------------------------------------ Edit this bug report at http://bugs.php.net/?id=13950&edit=1
