Regular expression question

Using php I would like to detect something in a string depending on whether the part immediately after the matched part does not contain certain characters. I think I may need to use a lookahead negative assertion as explained here but it is not working as I would expect so not sure. So for example:

Code:

$string = 'test aadfadf random text kalkdfjakdf>apple peach orange';

I want an expression that will detect everything up to the > so long as apple does not immediately follow the >

I tried

Code:

if(preg_match("/test(.*)>(?!apple))/i",$string)){

echo 'true since apple does not follow > in string';

}else{

echo 'false since apple follows > in string';

}

When the string contains apple after the > it returns false as I expect and need but when I change the string to have peach after the > instead of apple it still returns false and I need it to return true. Any ideas?
