PHP replace string with value from array

Question

I'm trying to replace words in a string with words from an array. Problem is the result repeated multiple times. I know there is a gotcha for str_replace, but i can't find any solution for this problem.

I tried with str_replace and preg_replace.

My codes:

With str_replace:

$text = 'Amir and Mahdi are friends.';
$text2 = str_replace(array("Amir","Mahdi"), '{Amir|Mahdi}', $text);

Result: {Amir|{Amir|Mahdi}} and {Amir|Mahdi} are friends.

With preg_replace:

$text = 'Amir and Mahdi are friends.';
$text2 = preg_replace(array("/Amir/","/Mahdi/"), '{Amir|Mahdi}', $text);

Result: {Amir|{Amir|Mahdi}} and {Amir|Mahdi} are friends.

I want this result: {Amir|Mahdi} and {Amir|Mahdi} are friends.

with replace patter as array it first converts {Amir|Mahdi} and Mahdi are friends., again for arrays second index Mahdi it converts both Mahdi. That's why I suggest you to use | (OR) condition in pattern instead of array.

$text = 'Amir and Mahdi are friends.';
$text2 = preg_replace("/Amir|Mahdi/", '{Amir|Mahdi}', $text);
echo $text2;

Working demo.
