ID: 55180 Updated by: ahar...@php.net Reported by: jonasvdegn at hotmail dot com Summary: substr return is fail -Status: Open +Status: Bogus Type: Bug -Package: Output Control +Package: Strings related Operating System: Windows 7 PHP Version: 5.3.6 Block user comment: N Private report: N New Comment: Sorry, but your problem does not imply a bug in PHP itself. For a list of more appropriate places to ask for help using PHP, please visit http://www.php.net/support.php as this bug system is not the appropriate forum for asking support questions. Due to the volume of reports we can not explain in detail here why your report is not a bug. The support channels will be able to provide an explanation for you. Thank you for your interest in PHP. The third parameter for substr() is the number of characters to return, not the end position.

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 this bug report at https://bugs.php.net/bug.php?id=55180&edit=1
