ereg() is a "find" function used if you want to match a pattern, and ereg_replace() is a replace function. The "i" just ignores case. In other words, if you just want to find out if an email address is in the correct format:

if (ereg("^(.+)@(.+)\\.(.+)$", $email)
echo "Email is valid";
else
echo "Email is not valid";

But if you want to replace a pattern with another one (in this case change "hello there" to "HellO there&quot:

echo ereg_replace("h(ell)o", "H\\1O", "hello there"

Does that help?

Of sorts, thanx

How would u get it to replace A value of Y with a value of X ( x and y could be any numeric value)

So it writes to a file "video.txt" and replaces value X with value Y

eg:

x=1
y=2

so 1 would be replaced with 2 in the file.

Can u help?

thanx

So are you saying you want to replace all "1" with "2" and write the result to video.txt? If so:

$inputStr = "There is a 1 in this string.";
$outputStr = ereg_replace("1", "2", $inputStr);
$fp = fopen("video.txt", "w"
fwrite($fp, "$outputStr"
fclose($fp);
