How to add multiple lines to csv file?

Question

PHP

Parsing I get data from the site.
for() - product pages
foreach() - for each product separately
In foreach I open a file
I create an array with column headings.
And then you need to add the lines themselves.
How can I add more?

1) you can convert an array with product properties to a string:
$strTovar = implode("\t", $arrayTovar);
2) if there are several products, then we create an array of strings, let's say $arrayVseTovary, where such strings will be placed,
3) then we convert this array into one common string:
$strVseTovary = implode("\r\n", $arrayVseTovary);
4) after that, just write the $strVseTovary string to the CSV file, for example, using file_put_contents()
