DOWNLOAD META TAG GENERATOR

sebelum masuk ke fungsi kita butuh rangkaian kata untuk kata / keyword yang nantinya tidak diharapkan muncul pada hasi generate, sebenarna hanya untuk pembanding sajah.

commonwords.php

Code:

<?php
$commonwords = <<<EOF
Copyright wwwdremiinfo
EOF;

?>

dan satu lagi file untuk memfilter kata yang diharapkan muncul ..

expectedwords.php

Code:

<?php
$expectwords = <<<EOF
tutorial photoshop
EOF;
?>

Code:
