[A previous version of this function which I wrote] did not parse empty cells at the end of a line
correctly. Here's the fixed version. Thanks to Graham Lawrence for the fix.
<?php
function
parse_csv($file,$comma=',',$quote='"',$newline="\\\\n")
{
$db_quote = $quote . $quote;
// Clean up file
$file = trim($file);
$file = str_replace("\\\\r\\\\n",$newline,$file);
$file = str_replace($db_quote,'"',$file); // replace double quotes with
" HTML entities
$file = str_replace(',",',',,',$file); // handle
,"", empty cells correctly
$file = str_replace(","\\\\n",",\\\\n",$file); // handle
,""\\\\n empty cells correctly at the end of lines
$file .= $comma; // Put a comma on the end, so we parse last cell
$inquotes = false;
$start_point = 0;
$row = 0;
$cellNo = 0;
for($i=0; $i<strlen($file); $i++) {
$char = $file[$i];
if ($char == $quote) {
if ($inquotes) {
$inquotes = false;
}
else {
$inquotes = true;
}
}
if (($char == $comma or $char == $newline) and !$inquotes) {
$cell = substr($file,$start_point,$i-$start_point);
$cell = str_replace($quote,'',$cell); // Remove delimiter quotes
$cell = str_replace('"',$quote,$cell); // Add in data quotes
if ($row>0) $data[$row][$data[0][$cellNo]] = $cell;
else $data[$row][] = $cell;
$cellNo++;
$start_point = $i + 1;
if ($char == $newline) {
$cellNo = 0;
$row ++;
}
}
}
return $data;
}
?>
