我们帮助他们:

代码之前:

if ( ! eregi("convert$", $this->library_path))
        {
            if ( ! eregi("/$", $this->library_path)) $this->library_path .= "/";

            $this->library_path .= 'convert';
        }

if (eregi("gd2$", $protocol))
        {
            $protocol = 'image_process_gd';
        }

代码然后:

if ( ! preg_match("convert$/i", $this->library_path))
        {
            if ( ! preg_match("/$/i", $this->library_path)) $this->library_path .= "/";

            $this->library_path .= 'convert';
        }

if (preg_match("gd2$/i", $protocol))
        {
            $protocol = 'image_process_gd';
        }

preg_match 期望它的正则表达式参数在一对分隔符内.

所以尝试:

if ( ! preg_match("#convert$#i", $this->library_path)) {
        if ( ! preg_match("#/$#i", $this->library_path)) 
                $this->library_path .= "/";

        $this->library_path .= 'convert';
}

if (preg_match("#gd2$#i", $protocol)) {                                         
        $protocol = 'image_process_gd'; 
}
