Unable to import Full "CSV" rows using "PHP" Ajax - php

Question

I'm using getcsv to import csv into database.I have huge number of datasheets in csv format. Currently i'm importing a csv which has 53,000 rows and 35 columns. when i decerase columns it's importing approx all the rows in database, but it's not importing when i want to import all the columns of csv into mysql table.
my csv has all type of character like char,numbers, symbols,specila charaters etc
Please look at my code:
Index.php:
<form action="upload.php" method="post" enctype="multipart/form-data"> <input type="text" name="type2" Placeholder='Type Folder Name' required > <input type="file" name="csv">
<input type="submit" name="submit" value="Import" class="btn btn-success waves-effect waves-light"/>
</form>
UPLOAD.php
<script>
//Declaration of function that will insert data into database
function senddata(filename){
var file = filename;
$.ajax({
type: "POST",
url: "senddata.php",
data: {file},
async: true,
success: function(html){
$("#result").html(html);
}
})
}
</script>
