Find matches by word and check if it's a link or not

I want to create a PHP array like below, which contains two values, one for the matching word and one to check if the match is a link or not.

Input

$string = "test <a href=\"test\" title=\"test\">test</a>"

What can I do here to find all matches of the word 'test' and check if the founded match is a link or not?

Output

Array
(
    [0] => 
           Array 
           (
               [0] test
               [1] false
           )
    [1] => 
           Array 
           (
               [0] test
               [1] true
           )
)

You could use a regular expression for this:

$string = 'test <a href="http://test" title="mytitle">link text</a>';

if (preg_match("#^\s*(.*?)\s*<a\s.*?href\s*=\s*['\"](.*?)['\"].*?>(.*?)</a\s*>#si",
         $string, $match)) {
    $textBefore = $match[1]; // test
    $href       = $match[2]; // http://test     
    $anchorText = $match[3]; // link text
    // deal with these elements as you wish...
}

This solution is not case-sensitive, it will work with <A ...>...</A> just as well. If the href value is delimited with single quotes instead of double quotes, it will still work. Surrounding spaces of each value are ignored (trimmed).

Try this code :

<?php

    $string ="test <a href=\"test\" title=\"test\">test</a>";
    $link ='';
    $word = '';
    $flag = true;
     for($i=0;$i<strlen($string);$i++){

       if($string[$i] == '<' && $string[$i+1] == 'a'){
         $flag=false;
         while($string[$i++] != '>')
         {

         }
         while($string[$i] != '<' && $string[$i+1] != '/' && $string[$i+2] != 'a' && $string[$i+3] != '>'){
             $link .= $string[$i++];
           }
       }
       else{
        if($flag)
          $word.=$string[$i];
       }
     }
    echo 'Link :'.$link . "<br/>";
    echo 'Word:'.$word;
    // You can now manipulate Link and word as you wish 

    ?>
