if and echo

[sriram]

code:
if(!echo(1<2))
echo 'true';

This shows error can any one explain this?

echo is not part of an evaluation.

if( 1 < 2 ) echo("true");

Look at this.

Yeah, your using echo incorrectly. Echo only outputs a string.

For instance if the string is "this is text", echo will display "this is text" as text on the page.

So:

if(!echo(1<2))
echo 'true'; 

Is very wrong. But this:

$i = 1;

if($i < 2) {
echo "true"; 
}

(if $i is less than 2, then display the word "true" on the page... )
