Big CSV upload - filename could not be empty - php

Question

Using php 5.4.34 And Laravel 4 with apache 2.2.22 and Ubuntu.
Using the library https://github.com/goodby/csv to parse a csv uploaded.
here is my code :
$file = Input::file('file');
//echo $file->getClientOriginalName();
$config = new LexerConfig();
$config
->setDelimiter(";")
->setToCharset('UTF-8')
;
$lexer = new Lexer($config);
$interpreter = new Interpreter();
$salarie_csv = [];
$errors = [];
$lineNb = 0;
$interpreter->addObserver(function (array $rows) use (&$salarie_csv, &$lineNb, &$errors) {
//some code
});
$lexer->parse($file, $interpreter);
return Response::json($errors, 200);
When I upload a 1.5Mb size csv with 20.000 rows it works.
When I upload a 2.5Mb size csv with 38.500 rows it give me the error :
SplFileObject::__construct():Filename cannot be empty in Lexer.php line 50.
i tried with the same file (just removed or add some rows for the test)
Is there a way to fix this ?

Answer 1

Check your post_max_size and upload_max_filesize in your php.ini config file.
PHP probably does not allow too big files to be uploaded, so it cuts it off from post.
var_dump( ini_get('post_max_size') );
Note, that post_max_size overrides upload_max_filesize (as explained in answer here), you should make sure that both of those settings allow sizes that you'll be uploading.

Answer 2

Try This..........
$type=$_FILES['file']['type'];
$filename=$_FILES["file"]["tmp_name"];
$filename_csv = explode(".", $_FILES["file"]["name"]);
$extension = end($filename_csv);
if($extension=="csv")
{
if($_FILES["file"]["size"] > 0)
{
$file = fopen($filename, "r");
while (($emapData = fgetcsv($file, 10000, ",")) !== FALSE)
{
$sql = mysql_query("insert into upload_data(spent,click,filename,date) values('$emapData[0]','$emapData[1]','$emapData[2]','$emapData[3]')") or die (mysql_error());
mysql_query($sql);
}
fclose($file);
echo $error1=ucwords('<div style="margin-left:60px;position: absolute;width: 400px; color: #006400;">CSV File has been successfully Imported</div>');
}
}
else
{
echo $error1=ucwords('<div style="margin-left:60px;position: absolute;width: 400px; color: #CC0000;">Invalid File:Please Upload CSV File</div>');
// echo 'Invalid File:Please Upload CSV File';
}
