Marc et al:
I joined late into this conversation, so I may be missing the point, but you want to discus strangeness try this:
<?php
if (($a = 'foo') | ($b = 'bar')) // <-- note the single pipe ( | )
{
echo "$a <br > $b";
}
else
{
echo 'Neither are populated';
}
?>
However, the above practice of using one '=' is questionable -- the following is better.
<?php
$a = 'foo';
$b = 'bar';
if (($a == 'foo') | ($b == 'bar'))
{
echo "$a <br > $b";
}
else
{
echo 'Neither are populated';
}
?>
Comment out the variables to see how things work. Also change the number of pipes to see how things change.
To the more accomplished programmers reading this, here's a question:
What's the difference between using one pipe or two in an 'if' statement? :-)
Cheers,
