The contents of the PHP database are saved as an array in the file

$res =mysql Tutorial _query ("Select K1,k2 from". Table (' keywords '). " ") ;
$STR = "<?php rn";
while ($rs =mysql_fetch_array ($res))
{

$str. = "$keyword ['". $rs [0]. "'] = ' ". $rs [1]." '; RN ";
}
$str. = "?>";
File_put_contents ("keyword.php", $str);
echo "Export Success";

Method Two

$f =file_get_contents ("W1.txt");
$f =str_replace ("RN", "<br>", $f);//Replace line feed
$arr =explode ("<br>", $f);
$STR = "<?php rn";
foreach ($arr as $t)
{
$rs =explode ("|", $t);
Cannot contain? and other special symbols
$str. = "$keyword ['] Str_replace ("? "," ", $rs [0]). = ' ". Str_replace ("? "," ", $rs [1])." '; RN ";

}
$str. = "?>";
File_put_contents ("keyword.php", $str);
echo "Export Success";
