Bug #13270 Odd Math/String behaviour when 'echo'ing...
Submitted: 2001-09-12 14:55 UTC Modified: 2001-09-12 16:58 UTC
From: SeanECoates at yahoo dot ca Assigned:
Status: Not a bug Package: Math related
PHP Version: 4.0.6 OS: Windows 2000
Private report: No CVE-ID: None

The following code produces strange output:
<?php
 echo "one".  1+2  ."two<br>\n";
 echo "one". (1+2) ."two<br>\n";
?>
(output:)
2two
one3two

maybe I'm overlooking something, but when excluding the parentheses, causes the first "one" to not display, and the addition to work incorrectly.
Please email me if you need more details. Obviously, the workaround is to put parentheses around the math.

Is this because, without parentheses, PHP is treating the statement like this:

echo "one1" + "2two"; // or something similar?

Using PHP4.0.6, Win32 pre-compiled. Other systems untested.

Just a matter of operator precedence:

Not a bug. (. is just another operator, as is + )
