PHP将所有数组值搜索到另一个每个数组值中

好的，这是我想做的

我有一个包含关键字的数组

$keywords = array('sport','messi','ronaldo','Barcelona','madrid','club','final','cup','player');

我还有另一个数组，它包含了我的全部标题

比方说

$titles = array('Real Madrid is the only club to have kept a European cup by winning it five times in a row.','Cristiano Ronaldo is World Soccer's Player of the Year 2013.','Lionel Messi Reaches $50 Million-A-Year Deal With Barcelona','','');

那么现在我想做什么呢

是在每个titles数组元素中循环我的关键字数组

如果一个元素中有3个关键字，那么做些什么

比如说

$titiles[0] // this one has these words => Madrid , cup club

所以这一个是有至少3个字的我的关键字

因此，如果每个元素有3个或更多关键字，则回显该数组元素

你知道怎么让它工作吗

foreach ($titles as $t){

$te=explode(' ',$t);

$c=count(array_intersect($te,$keywords));

if($c >=3){
echo $t.' has 3 or more matches';
}

} 

现场演示：

2个匹配项是您当前的最大匹配项

如果你想马德里与马德里

$keywords=array_map('strtolower', $keywords);
foreach ($titles as $t){

$te=explode(' ',$t);
$comp=array_map('strtolower', $te);

$c=count(array_intersect($comp,$keywords));



   if($c >=3){
   echo $t.' has 3 or more matches';
   }

}

   }

}

或者，您也可以使用

substr\u count（）

获取发生次数。考虑这个例子：

$keywords = array('sport','messi','ronaldo','Barcelona','madrid','club','final','cup','player');
$titles = array('Real Madrid is the only club to have kept a European cup by winning it five times in a row.',"Cristiano Ronaldo is World Soccer's Player of the Year 2013.","Lionel Messi Reaches $50 Million-A-Year Deal With Barcelona",'','');
$count = 0;
$data = array();
foreach($titles as $key => $value) {
    $value = strtolower($value);
    $keys = array_map('strtolower', $keywords);
    foreach($keys as $needle) {
        $count+= substr_count($value, $needle);
    }
    echo "In title[$key], the number of occurences using keywords = " .$count . '<br/>';
    $count = 0;
}

更简单的数组_intersect:

$keywords = array('sport','messi','ronaldo','Barcelona','madrid','club','final','cup','player');

$titles = array('Real Madrid is the only club to have kept a European cup by winning it five times in a row.','Cristiano Ronaldo is World Soccer\'s Player of the Year 2013.','Lionel Messi Reaches $50 Million-A-Year Deal With Barcelona');

foreach($titles as $title) {
    if (count(array_intersect(explode(' ',strtolower($title)), $keywords)) >= 3) {
        //stuff
    }
}

使用数组_intersect更简单：

$keywords = array('sport','messi','ronaldo','Barcelona','madrid','club','final','cup','player');

$titles = array('Real Madrid is the only club to have kept a European cup by winning it five times in a row.','Cristiano Ronaldo is World Soccer\'s Player of the Year 2013.','Lionel Messi Reaches $50 Million-A-Year Deal With Barcelona');

foreach($titles as $title) {
    if (count(array_intersect(explode(' ',strtolower($title)), $keywords)) >= 3) {
        //stuff
    }
}

循环标题，在空格上分解，在分解的vs$KEYONS count（）结果上运行array_intersect（），在空格上分解，在分解的vs$KEYONS count（）结果上运行array_intersect（），但是为什么在第一个foreach末尾又写了$count呢loop@HasanZohdy不客气，这只会重置计数器。每个标题都有一个计数。所以在一个标题迭代之后，你需要重新设置它，为下一个标题做准备。在第二个foreach对我来说更有意义之前，只需设置一次就可以了。谢谢，伙计，但是为什么你在第一个foreach末尾又写了$count呢loop@HasanZohdy不客气，这只会重置计数器。每个标题都有一个计数。所以在一个标题的迭代之后，你需要重新设置它，为下一个标题做准备，只需设置一次，在第二个foreach对我来说更有意义之前。
