From: Operating system: Windows 7 PHP version: 5.3.6 Package: Output Control Bug Type: Bug Bug description:substr return is fail
Description: ------------ the substr(string,from,to) failed and return something i find strange, and never seen it before.. my version is also 5.3.5 but i chose 5.3.6 because the 5.3.5 is not there. Test script: --------------- $x=1; while ($x<=strlen("hello")) { $xx=$x-1; echo substr("hello",$xx,$x); $x++; } echo "<br/>"; $x=1; while ($x<=strlen("hello")) { $xx=$x-1; echo $xx." "; echo $x." "; echo substr("hello",$xx,$x); echo "<br/>"; $x++; } Expected result: ---------------- i expect a result saying: hello 0 1 h 1 2 e 2 3 l 3 4 l 4 5 o like in substr("hello",0,1) substr("hello",1,2) and continue like that. Actual result: -------------- the actual result is: hellloloo 0 1 h 1 2 el 2 3 llo 3 4 lo 4 5 o like substr("hello",1,2) is "el" how can that be? and substr("hello",2,3) is "llo" and how can that be too? -- Edit bug report at https://bugs.php.net/bug.php?id=55180&edit=1 -- Try a snapshot (PHP 5.2): https://bugs.php.net/fix.php?id=55180&r=trysnapshot52 Try a snapshot (PHP 5.3): https://bugs.php.net/fix.php?id=55180&r=trysnapshot53 Try a snapshot (trunk): https://bugs.php.net/fix.php?id=55180&r=trysnapshottrunk Fixed in SVN: https://bugs.php.net/fix.php?id=55180&r=fixed Fixed in SVN and need be documented: https://bugs.php.net/fix.php?id=55180&r=needdocs Fixed in release: https://bugs.php.net/fix.php?id=55180&r=alreadyfixed Need backtrace: https://bugs.php.net/fix.php?id=55180&r=needtrace Need Reproduce Script: https://bugs.php.net/fix.php?id=55180&r=needscript Try newer version: https://bugs.php.net/fix.php?id=55180&r=oldversion Not developer issue: https://bugs.php.net/fix.php?id=55180&r=support Expected behavior: https://bugs.php.net/fix.php?id=55180&r=notwrong Not enough info: https://bugs.php.net/fix.php?id=55180&r=notenoughinfo Submitted twice: https://bugs.php.net/fix.php?id=55180&r=submittedtwice register_globals: https://bugs.php.net/fix.php?id=55180&r=globals PHP 4 support discontinued: https://bugs.php.net/fix.php?id=55180&r=php4 Daylight Savings: https://bugs.php.net/fix.php?id=55180&r=dst IIS Stability: https://bugs.php.net/fix.php?id=55180&r=isapi Install GNU Sed: https://bugs.php.net/fix.php?id=55180&r=gnused Floating point limitations: https://bugs.php.net/fix.php?id=55180&r=float No Zend Extensions: https://bugs.php.net/fix.php?id=55180&r=nozend MySQL Configuration Error: https://bugs.php.net/fix.php?id=55180&r=mysqlcfg Try a snapshot (PHP 5.4): https://bugs.php.net/fix.php?id=55180&r=trysnapshot54
