Search for words in text, and replace them

I'm having a hard time finding the solution to my problem.

I have an array like this in a variable:

$myarray = Array (
[0] => Orange
[1] => Black
[2] => White
[3] => Yellow
[4] => Red
);

Basically, I need search the words of the array in the string, and replace them with the same ones, but with links.

For example, from:

$string = "My content contains orange and also blue";

To:

$string = "My content contains <a href="www.domain.com/orange">orange</a> and also blue";

Use str_ireplace and do it using arrays:

$from = array(
    "Orange",
    "Black",
    "White",
    "Yellow",
    "Red"
);

$to = array(
    '<a href="www.domain.com/orange">orange</a> ',
    '<a href="www.domain.com/black">black</a>',
    '<a href="www.domain.com/white">white</a>',
    '<a href="www.domain.com/yellow">yellow</a>',
    '<a href="www.domain.com/red">red</a>'
);

$string = str_ireplace($from, $to, $string);

Edit 1: This also replaces all strings if they are met inside the array, meaning that if you have orange and black in the string, those two will get replaced.

You can use str_ireplace, check the link

$string = "My content contains orange and also black";
$string = str_ireplace("orange","<a href='http://www.example.com/orange'>orange</a>",$string);

EDIT

As @Ericki has edited the question, please use the below code to achieve the same,

$myarray = array (
'Orange','Black','White','Yellow','Red'
);
$string = "My content contains Orange, Black, Yellow, Red";

foreach($myarray as $item){
    if (strpos($string, $item)) {
        $string = str_ireplace($item,"<a href='http://www.example.com/".$item."'>$item</a>",$string);
    }
}   
var_dump($string);

This is probably best achieved using preg_replace. We can create a regex by using implode to create an alternation of each of the words in $myarray; capture that word in a group and then use it in the replacement to add the link around it:

$string = "My content contains orange and also blue in a blackout";

$string = preg_replace('/\b(' . implode('|', $myarray) . ')\b/i', '<a href="www.domain.com/$1">$1</a>', $string);
echo $string;

Output:

My content contains <a href="www.domain.com/orange">orange</a> and also blue in a blackout

Demo on 3v4l.org

Note that by using a regex with word boundaries (\b) we can avoid unintentionally replacing black in blackout with a link.
