#28292 [NEW]: __toString() does not work in echo "x=$x"

From: php at koteroff dot ru Operating system: Windows PHP version: 5.0.0RC2 PHP Bug Type: Zend Engine 2 problem Bug description: __toString() does not work in echo "x=$x" Description: ------------ Method __toString() work in PHP5 RC1 correctly, but in PHP4 RC2 - wrong (in today CVS - too). Bewitched method? :-) There are so many bugs and changes around them in all PHP versions... I'm finishing the book about PHP5, please say if __toString() behavour will be changed in release. P.S. I cannot understand too why this method is called only in print and echo functions - thanks to it I cannot write function myecho($s) { echo $s; } myecho("x=$x"); But, I think, it is another question. Reproduce code: --------------- <? class C { function __toString() { return "s"; } } $x = new C; echo "x=$x"; ?> Expected result: ---------------- x=s Actual result: -------------- x=Object id #1 (and NO warning or notice) -- Edit bug report at http://bugs.php.net/?id=28292&edit=1 -- Try a CVS snapshot (php4): http://bugs.php.net/fix.php?id=28292&r=trysnapshot4 Try a CVS snapshot (php5): http://bugs.php.net/fix.php?id=28292&r=trysnapshot5 Fixed in CVS: http://bugs.php.net/fix.php?id=28292&r=fixedcvs Fixed in release: http://bugs.php.net/fix.php?id=28292&r=alreadyfixed Need backtrace: http://bugs.php.net/fix.php?id=28292&r=needtrace Need Reproduce Script: http://bugs.php.net/fix.php?id=28292&r=needscript Try newer version: http://bugs.php.net/fix.php?id=28292&r=oldversion Not developer issue: http://bugs.php.net/fix.php?id=28292&r=support Expected behavior: http://bugs.php.net/fix.php?id=28292&r=notwrong Not enough info: http://bugs.php.net/fix.php?id=28292&r=notenoughinfo Submitted twice: http://bugs.php.net/fix.php?id=28292&r=submittedtwice register_globals: http://bugs.php.net/fix.php?id=28292&r=globals PHP 3 support discontinued: http://bugs.php.net/fix.php?id=28292&r=php3 Daylight Savings: http://bugs.php.net/fix.php?id=28292&r=dst IIS Stability: http://bugs.php.net/fix.php?id=28292&r=isapi Install GNU Sed: http://bugs.php.net/fix.php?id=28292&r=gnused Floating point limitations: http://bugs.php.net/fix.php?id=28292&r=float
