Writing your own CSV code is probably a waste of your time  just use a package such as league csv - it deals with all the difficult stuff for you  the documentation is good and it s very stable   reliable   http   csv thephpleague com   You ll need to be using composer  If you don t know what composer is I highly recommend you have a look  https   getcomposer org

First make data as a String with comma as the delimiter  separated with       Something like this   CSV string  No Date Email Sender Name Sender Email  n     making string  So   n  is used for newLine   rand   rand 1 50     Make a random int number between 1 to 50   file   export export   rand   csv     For avoiding cache in the client and on the server                                         side it is recommended that the file name be different   file put contents  file  CSV string       Or try this code if  CSV string is an array     fh  fopen  file   w        fputcsv  fh    CSV string            n            is delimiter      n  is new line      fclose  fh

The thread is a little old  I know  but for future reference and for noobs as myself   Everyone else here explain how to create the CSV  but miss a basic part of the question  how to link  In order to link to download of the CSV-file  you just link to the  php-file  which in turn responds as being a  csv-file  The PHP headers do that  This enables cool stuff  like adding variables to the querystring and customize the output    lt a href  my csv creator php user 23 amp amp othervariable true  gt Get CSV lt  a gt    my csv creator php can work with the variables given in the querystring and for example use different or customized database queries  change the columns of the CSV  personalize the filename and so on  e g    User John Doe 10 Dec 11 csv

The thread is a little old  I know  but for future reference and for noobs as myself   Everyone else here explain how to create the CSV  but miss a basic part of the question  how to link  In order to link to download of the CSV-file  you just link to the  php-file  which in turn responds as being a  csv-file  The PHP headers do that  This enables cool stuff  like adding variables to the querystring and customize the output    lt a href  my csv creator php user 23 amp amp othervariable true  gt Get CSV lt  a gt    my csv creator php can work with the variables given in the querystring and for example use different or customized database queries  change the columns of the CSV  personalize the filename and so on  e g    User John Doe 10 Dec 11 csv
