Question

整个上午都在摸不着头脑，似乎没有想到一个合乎逻辑的快速方法，不使用大量资源。

这是方案，

$content = "hello this is a lovely website that people help me with and i love it";
$arrayto = array("good morning","hello","good afternoon","morrow");
$website = "http://www.google.com";

我想检查$ content，如果它包含一个数组单词，如果它确实将$website作为href=""转换为链接，然后立即停止它找到了一个。

那么$content就是"<a href="$website">hello</a> this is a lovely website that people help me with and i love it";。

由于

Answer 1

来源link str_replace可能是一个答案

// Provides: You should eat pizza, beer, and ice cream every day
    $phrase  = "You should eat fruits, vegetables, and fiber every day.";
    $healthy = array("fruits", "vegetables", "fiber");
    $yummy   = array("pizza", "beer", "ice cream");

    $newphrase = str_replace($healthy, $yummy, $phrase);

Answer 2

这样做 -

<?php

$content = "hello this is a lovely website that people help me with and i love it";
$arrayto = array("good morning","hello","good afternoon","morrow");
$website = "http://www.google.com";

$data=explode(' ', $content);
$final=array();

foreach ($data as $key ) {

    if(array_search($key, $arrayto))
    {
        $word='<a href='.$website.'>'.$key."</a>";
        array_push($final, $word);
    }
    else
    {
      array_push($final, $key);
    }
}

$res=implode(' ', $final);

print_r($res);

?>

OUTPUT- hello这是一个可爱的网站，人们帮助我，我喜欢它

Answer 3

使用str_replace

可以不使用正则表达式

 <?php
    $content = "hello this is a lovely website that people help me with and i love it";
    $arrayto = array("good morning","hello","good afternoon","morrow");
    $website = "http://www.google.com";

    foreach($arrayto as $v){
     if(strpos($content,$v)!==false){
   $content= str_replace("$v","<a href=$website>$v</a>",$content);
        }
    }
    echo $content;

<强>输出：

<a href=http://www.google.com>hello</a> this is a lovely website that people help me with and i love it

Answer 4

$content = "hello this is a lovely website that people help me with and i love it";
$arrayto = array("good morning","hello","good afternoon","morrow");
$website = "http://www.google.com";
while($item = each($arrayto)){
    if(strstr($content, $item['value'])!==false){
        $content = str_replace($item['value'], '<a href="'.$website.'">'.$item['value'].'</a>', $content);
        break;
    }
}

您可以使用功能strstr。

Answer 5

这可以通过有效的方式解决，而无需使用preg_replace：

进行循环

$content = "hi hello and bye";
$words = array('hello', 'bye');
$website = "http://www.google.com";

$regex = '/\b(' . implode('|', $words) . ')\b/';
echo preg_replace($regex, "<a href='$website'>$1</a>", $content, 1);

请注意，如果您只想替换整个单词，则必须使用正则表达式和\b位，否则会将helloween变为<a...>hello</a>ween。

检查字符串以查看它是否包含数组中的一个字符串
