$mime) { $contents=file_get_contents($file); $base64=base64_encode($contents); echo "data:$mime;base64,$base64";} |
8.创建更加友好的页面标题SEO URL
输入示例：$title = “This foo’s bar is rockin’ cool!”; echo makeseoname($title); //RETURNS: //this-foos-bar-is-rockin-cool

{ return preg_replace('/[^a-z0-9_-]/i', '',
strtolower(str_replace(' ', '-',
