php菜鸟教程:一招教你怎么样识别真假百度蜘蛛
<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;">本文介绍PHP<span style="color: black;">怎样</span>识别蜘蛛的真实性,<span style="color: black;">重点</span>是<span style="color: black;">经过</span><span style="color: black;">有些</span>组合手段对搜索引擎蜘蛛的真实性进行判断,让虚假蜘蛛无处可逃。我<span style="color: black;">晓得</span>部分站长为了安全起见,都会屏蔽假人<span style="color: black;">拜访</span>,<span style="color: black;">然则</span>会对蜘蛛敞开<span style="color: black;">前门</span>,<span style="color: black;">倘若</span><span style="color: black;">此时</span>候有人伪装成蜘蛛,对你的网站为所欲为,那岂不是<span style="color: black;">无</span>一点安全感吗?之前我介绍过PHP<span style="color: black;">怎样</span>识<span style="color: black;">拜访</span>者是不是搜索引擎的<span style="color: black;">设备</span>(参考<span style="color: black;">文案</span>《PHP<span style="color: black;">怎样</span>识别蜘蛛:全网最新最全蜘蛛整理》),<span style="color: black;">这儿</span>就不对识别蜘蛛的<span style="color: black;">办法</span>进行<span style="color: black;">仔细</span>介绍了,本文<span style="color: black;">重点</span>是介绍<span style="color: black;">怎样</span>识别蜘蛛的真假。</p>
