Description:
------------
<?php
 $myDS=array(1,2,3);
 false===($targetKey=array_search(3,$myDS)) or var_dump($targetKey);  
 // outputs:2

 false===($targetKey=array_search(3,$myDS)) or unset($myDS[$targetKey]);   
 //  Fail:this is a syntax error!(Actually I just want to remove the target element with specified value from the array-$myDS,but it does not work!)



Test script:
---------------
<?php
 $myDS=array(1,2,3);
 false===($targetKey=array_search(3,$myDS)) or var_dump($targetKey);  
 // outputs:2

 false===($targetKey=array_search(3,$myDS)) or unset($myDS[$targetKey]);   
 //  Fail:this is a syntax error!(Actually I just want to remove the target element with specified value from the array-$myDS,but it does not work!)

 =>So ,I hope "unset" keyword  can be used after "or" keyword,Thank you !

Expected result:
----------------
Actually "exit" keyword can be used after "or" keyword,why not "unset"?
for example:
!defined('IN_MANAGE') or exit('no access for this site!'); // works successfully

I hope "unset" keyword  can be used after "or" keyword,Thank you !
for example:
!isset($somekey) or unset($myDS[$somekey]);

Actual result:
--------------
Actually "exit" keyword can be used after "or" keyword,why not "unset"?
for example:
!defined('IN_MANAGE') or exit('no access for this site!'); // works successfully

I hope "unset" keyword  can be used after "or" keyword,Thank you !
