escape comma and add new column while creating a csv file - php

Question

I am converting a Delimited FLAT file to CSV and it has some data which as comma in between them. For eg the product name Iphone 6splus, 32 gb. Since this a description of the product and can have special characters also. How do i escape the comma as because of this fputcsv is considering this data as a new line. which is wrong. I am using
$handle = fopen("data.txt", "r");
$lines = [];
$row_count=0;
if (($handle = fopen("data.txt", "r")) !== FALSE) {
while (($data = fgetcsv($handle, 1000, "\t")) !== FALSE) {
if($row_count>0)
{
$lines[] = $data;
}
$row_count++;
}
fclose($handle);
}
$fp = fopen('example.csv', 'w');
foreach ($lines as $line) {
fputcsv($fp, split('\*\*', $line));
}
fclose($fp);
I need to escape the value before i start converting the data and store into csv

Enclose the field in quotes, e.g.
field1_value,field2_value,"field 3,value",field4, etc...
To encode a quote, use ", a single quote symbol in a field will be encoded as "", and the whole field will become """". So if you see the following in e.g. Excel:
---------------------------------------
| regular_value |,,,"| ,"", |""" |"|
---------------------------------------
the CSV file will contain:
regular_value,",,,""",","""",","""""""",""""
A comma is simply encapsulated using quotes, so , becomes ",".
A command and quote needs to be encapsulated and quoted, so "," becomes """,""".
