Unexpected output with echo statement.

Reproduce code:

// Expression 1
echo 'echo "<bob ".func()."></bob>";';

// Newline for "view source"
echo "\n";

// Expression 2
echo 'echo "<bob value=".func()."></bob>";';

// Newline for "view source"
echo "\n";

// Expression 3
echo 'echo "bob ".func()."></bob>";';


Expected result:
echo "<bob ".func()."></bob>";

echo "<bob value=".func()."></bob>";

echo "bob ".func()."></bob>";

// Note extra newlines for ease of reading.

Actual result:
echo "<bob .func().></bob>";
echo "<bob value=".func()."></bob>";
echo "bob ".func()."></bob>";

Line 2 and 3 are expected.  Line 1 is just plain weird!

Note that the '=' after 'value' makes the output work correctly.  Bizarre.  I have looked in PHP books, the web and asked a couple of experts all to no avail.

You can reduce the original code down to:
echo 'echo "<bob =".func()."></bob>";';

and it will give expected result!  But remove the equals sign and the bug will occur.

Also note removing the first < (i.e. before bob) will work too.  (see expression 3).

I'm possibly having a REALLY bad coding day and making a REALLY simple error...

I would be very worried if the output wasn't what you got.
(you're using single quotes..are you sure you've pasted the right code here? :)

Check out "Actual result: Expression 1". The double quotes are missing around .func()

I should have made it more clear.

Works perfectly here.

Are you sure you are getting:

   echo "<bob ".func()."></bob>"

and not, as I am getting:

   echo "<bob .func().></bob>"

I am definitely not making this up :o)  I have just reinstalled PHP 5.0.3 and it STILL fails.

I think we need to investigate this further before closing it.

Yes, I *AM* sure.
Try it with PHP CLI and if it works - fix your browser/editor instead.

Thanks Tony.  I wasn't being awkard saying "are you sure?", it's just that I had double, nay triple checked my code, however your hint re browsers clinched it.

It fails on Mozilla Firefox and Netscape, but it works on Internet Explorer and Opera.  I had been unlucky as I only tested it on Firefox and Netscape, as I assumed it wasn't a browser problem, i.e. I've never had problems with PHP output and browsers before.

Thanks for everyone's help.  Very much appreciated.

** This problem is closed as it's a browser problem. **
