Following is an example PHP script that uses SOW to read in the message.txt template and fill in the fields.
<?php /* message.php example */ /* read, fill and output message.txt */ include 'dl_local.php'; dl_local("phpsowDL.so"); $ar= array(); $ar['header']= "Cruel Collection agency\nYou owe us, pay now!\n"; $ar['date']= 'December 01, 1938'; $ar['salute']= 'Mr. Right'; $ar['account']= '01010101'; $ar['past_due_days']= 'many many years'; $ar['amount_due']= '$0.01'; $env= new_env(); update_env($env,$ar); $sow = new_sow('message.txt'); stroke_sow($sow, $env); reap_sow($sow); ?>
