检查字符串以查看它是否包含数组中的一个字符串

Question

Been scratching my head all morning and cannot seem to think of a logical quick way of doing this, without using alot of resources.

Here is the scenario,

$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";

I would like to check the $content and if it contains one of the arrays words and if it does turn it into a link using the $website as the href="", and then stop as soon as it finds one.

So then $content would be "<a href="$website">hello</a> this is a lovely website that people help me with and i love it";.

Thanks

You can do without Regex using str_replace

 <?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;

OUTPUT:

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