This is a quick script to diff two files which contain email addresses putting the emails in file A which do not exist in file B into file C. Just for personal consumption really.
<?php
$audi_list = array();
$cerritos_list = file_get_contents("/Users/jgordon/Downloads/CerritosVW.csv");
$cerritos_list = str_replace(',', '', $cerritos_list);
$cerritos_list = explode("\n", $cerritos_list);
$common_list = file("/Users/jgordon/Downloads/Common.csv");
foreach ($common_list as $common) {
$found = false;
foreach ($cerritos_list as $cerritos) {
if (trim(strtolower($cerritos)) == trim(strtolower($common))) {
$found = true;
break;
}
}
if ( ! $found) {
$audi_list[] = $common;
}
}
$out = "Contains ".count($audi_list)." email addresses...or something like that\n".implode("", $audi_list);
file_put_contents("/Users/jgordon/Downloads/Audi.csv", $out);
?>
