note 88353 modified in function.str-getcsv by danbrown

After using several methods in the past to create CSV strings without using files (disk IO sucks), I finally decided it's time to write a function to handle it all. This function could use some cleanup, and the variable type test might be overkill for what is needed, I haven't thought about it too much. Also, I took the liberty of replacing fields with certain data types with strings which I find much easier to work with. Some of you may not agree with those. Also, please note that the type "double" or float has been coded specifically for two digit precision because if I am using a float, it's most likely for currency. I am sure some of you out there would appreciate this function. <?php function str_putcsv($array, $delimiter = ',', $enclosure = '"', $terminator = "\n") { # First convert associative array to numeric indexed array foreach ($array as $key => $value) $workArray[] = $value; $returnString = ''; # Initialize return string $arraySize = count($workArray); # Get size of array for ($i=0; $i<$arraySize; $i++) { # Nested array, process nest item if (is_array($workArray[$i])) { $returnString .= str_putcsv($workArray[$i], $delimiter, $enclosure, $terminator); } else { switch (gettype($workArray[$i])) { # Manually set some strings case "NULL": $_spFormat = ''; break; case "boolean": $_spFormat = ($workArray[$i] == true) ? 'true': 'false'; break; # Make sure sprintf has a good datatype to work with case "integer": $_spFormat = '%i'; break; case "double": $_spFormat = '%0.2f'; break; case "string": $_spFormat = '%s'; break; # Unknown or invalid items for a csv - note: the datatype of array is already handled above, assuming the data is nested case "object": case "resource": default: $_spFormat = ''; break; } $returnString .= sprintf('%2$s'.$_spFormat.'%2$s', $workArray[$i], $enclosure); $returnString .= ($i < ($arraySize-1)) ? $delimiter : $terminator; } } # Done the workload, return the output information return $returnString; } ?> --was-- After using several methods in the past to create CSV strings without using files (disk IO sucks), I finally decided it's time to write a function to handle it all.
