[PHP] Evaluating strings...
Hey, Thanks for the quick response on Retrieving parameters...
This is another that has me stumped...
if (trim($Line) = 'body') {
$InBody = true;
} elseif (trim($Line) = '/body') {
$InBody = false;
}
$Line is a line from a html file, I'm trying to parse through it to ignore
everything but the body section. When I run the above I get the
following...
Fatal error: Can't use function return value in write context in
C:\wwwRoot\anthony.maske\cfr.php on line 43
If I do this...
$Tag = trim($Line);
if ($Tag = 'body') {
$InBody = true;
} elseif ($Tag = '/body') {
$InBody = false;
}
Why won't the later work? What am I missing in the first snip...
Thanks again...!
Anthony

That should be ==
basically that is trying to set trim($line) to be equal to 'body'
which won't work (and you get an error message).
== means compare the values.
=== means compare the values AND the types (eg make sure they are both
integers or strings).

This assigns 'body' to $Tag - see below.
$InBody = true;
} elseif ($Tag = '/body') {
$InBody = false;
}

Another page for you to read:

You're confusing assignment and comparison. = is for assignment, you
have to use == or === for comparison.
