$text = str_replace(''', "'", $text);
}

At a guess, I'd say $textis an empty string (thanks Mark for pointing out the specifics)
猜测一下，我会说$text是一个空字符串（感谢 Mark 指出细节）
Edit: Also, another guess is you have the parameters in the wrong order. The method signature of strpos is
编辑：另外，另一个猜测是您的参数顺序错误。strpos 的方法签名是
int strpos ( string $haystack , mixed $needle [, int $offset = 0 ] )

For starters you going about it all wrong....
对于初学者来说，你所做的一切都错了......
- strpos may return a
false,"",0 - the first argument must be the hastack
- the second argument should be the needle.
- strpos 可能返回一个
false,"",0 - 第一个参数必须是hastack
- 第二个参数应该是针。
what you should do is:
你应该做的是：
if(false !== ($position = strpos($text,'''))) //Position Found and set in $position
{
//$position holds the offset to the needle.
$text = str_replace(''', "'", $text);
}

TRY ADDING double quotes on the on the variable $Text
尝试在变量上添加双引号 $Text
Change: if(strpos(''', $text)
改变： if(strpos(''', $text)
into: if(strpos(''', ".$text.")
进入： if(strpos(''', ".$text.")
if(strpos(''', ".$text.") === false)
{
$text = str_replace(''', "'", $text);
}

I experienced this error after removing ?> from the end of the themes function.php in WP, but the error was only reported once.
从WP中的themes function.php末尾删除?>后遇到此错误，但该错误仅报告一次。
