注意：未定义的偏移量：2，同时使用php从csv获取数据
问题描述：
I was trying to fetch the data from csv to display using php.Here is the code
<?PHP
$file_handle = fopen("dept.csv", "r");
while (!feof($file_handle) ) {
$line_of_text = fgetcsv($file_handle, 1024);
print ($line_of_text[0]) . " ". ($line_of_text[1]). ($line_of_text[2]) . "<BR>";
}
fclose($file_handle);
?>
I am getting the output but getting a notice msg :
Notice: Undefined offset: 2
How to solve it?
答
- You don't post such questions without providing the file
- Appears that there are either only 2 columns in csv file or 1 of the entries does not have the third column filled in
-
If you don't want to look into the file you can do this:
$file_handle = fopen("dept.csv", "r"); while (!feof($file_handle) ) { $line_of_text = fgetcsv($file_handle, 1024); print ($line_of_text[0]) . " ". ($line_of_text[1]); if (isset($line_of_text[2])) print($line_of_text[2]); print ("<BR>"); } fclose($file_handle);
