PHP If / Else related question

I am testing a script for one of my websites. I am looking for a certain condition to be met. If it is true, I am currently echoing text to a page. Otherwise (else) I am displaying a different message. Now I need to change this, but are not sure with the right command. Here is the existing code

if (code removed as not needed for this question()) {
    echo "The result is true";
} else {
    echo "The result is not true. Go somewhere else";
}

PHP:

The "If" echo should pretty much be replaced with "do nothing" = meaning - just finish displaying the page the code is embedded in. The "else" echo should be replaced with a redirect to another page. How would I do that? Thanks.

Not sure if I understand you correctly, but you can use the ! operator.

if (! condition)
{
   // Do something
}

PHP:

! means "if not". It's what the else would do basically.

 

Well, if there is no code html outputted before the if condition you can use the 'header' redirect. For example:

if ( this == that )
{
  // do nothing
}
else 
{
  header("Location: http://www.google.com/");
  exit;
}

PHP:

 

I am getting this error message when I try your suggestion, chopsticks.

Replacing " with ' helped ....

Thanks.

Instead of the header... you can also use...

echo "<script>window.open("--link--","_self")</script>";

This is a better approach using javascript

 

You probably have some html outputted to the page already or something. Placing it before any html is outputted may fix it.
