Replace string between two strings php

To use preg_replace, pass in the original string and a regular expression – the matching result will be returned. There is not much more to say about that method as you need to understand regular expressions to use it.

Here is a programmatic solution, possibly not the most efficient code, but gives you an indication of what it is doing.

$tagOne = "[";
$tagTwo = "]";
$replacement = "Jainish Senjaliya";

$text = "Hello, my name is [NAME]";

$startTagPos = strrpos($text, $tagOne);
$endTagPos = strrpos($text, $tagTwo);
$tagLength = $endTagPos - $startTagPos + 1;

$newText = substr_replace($text, $replacement, 
    $startTagPos, $tagLength);

echo $newText;
