内容标题抽取

PHP从内容里面随机抽取标题 - 摘要: 本文讲的是PHP从内容里面随机抽取标题, <?php   $temp=$LabelArray['内容']; $temp=preg_replace("%<[^>]+>%",',',$temp);//防止网址中字母被匹配 $temp=make_semiangl

<?php

 

$temp=$LabelArray['内容'];

$temp=preg_replace("%<[^>]+>%",',',$temp);//防止网址中字母被匹配

$temp=make_semiangle($temp);//半角转化

if(preg_match_all("%[[:punct:]]([^[:punct:]]{5,30})[[:punct:]]%u",$temp,$arr)){

$i=rand(0,count($arr[0])-1);

$LabelArray['标题']=$arr[1][$i];

}

// 全角半角转

function make_semiangle($str) 

    $arr = array('0' => '0', '1' => '1', '2' => '2', '3' => '3', '4' => '4',
