I’m not exactly sure about the format of your string, but here’s something to get you going.

You can use explode to convert a string with delimiters to an array. Then you can change a value and convert it back to a form delimited by, e.g. ":". You do this by using join, which is an alias for implode:

<?php
// initialize variable and print it
$s = "pritesh:name:nilesh:replace";
print("{$s}\n");

$s = explode(":", $s); // convert to array
$s[1] = "anotherName"; // change value

// convert back to foo:bar form and print
$s = join($s, ":");
print("{$s}\n");
?>

Putting that into a file example.php and running it on the command line:

$ php -q example.php
pritesh:name:nilesh:replace
pritesh:anotherName:nilesh:replace

As someone mentioned, if you need to handle more advanced formats you should learn how to use regular expressions in PHP.

Hope that helps!
