Bug description: Echo not producing correct result.
Description:
------------
Unexpected output with echo statement.
Reproduce code:
---------------
<?php
// 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...
