Creating downloadable CSV files using PHP

The phpMyAdmin allows us different ways to export the MySQL database Table data. One of a method is CSV. In this tutorial, I am using fputcsv() method to write data in a file.

This function takes each line of the CSV import file and runs it through PHP's fgetcsv function. This function is similar to fgets except that fgetcsv parses the line it reads for fields in CSV format and returns an array containing the fields read. The array is an indexed array, with the first item at 0, second at 1 and so on. In web browsers the value ‘attachment’ instructs the browser to offer the file for download with the suggested name — the file might otherwise be displayed in the browser window as if it were normal text.

This PHP function will import CSV and convert it to an associative array based on the column headings in the first row. To use, simply call the function with a valid filename as the only parameter. The function will return an associative array of the import CSV file contents. The import CSV must have column headings as the first row since these are used to create the associative array elements.

This function is similar to fgets except that fgetcsv parses the line it reads for fields in CSV format and returns an array containing the fields read. The array is an indexed array, with the first item at 0, second at 1 and so on. To get the associative array, the first row of data is used as the column headings, then a loop runs over each item in the array from fgetcsv and inserts it against the column heading.

The method of using associative arrays is far better than an indexed array, as it can often be confusing, cause errors trying to remember what piece of data is at any given numerical index, and code maintenance is often a minefield. If a new column is added to the data, you have to update all the indexes where that array is used. With an associative array, you access data via a name, so it does not matter what order the data is read in or how many columns are inserted, that name will remain constant.

Glad I bumped into this on my google search. I had two lists of symlinks, with 24 and 32 links to insert in two directories. As I'm on a virtual host with no access to the shell, I wanted a PHP script to do what bash would do from the command line. With this snippet I was able to loop through my lists and create the two sets of symlinks in micro milliseconds if I don't count the time spent typing the address in the browser.
