How to update the value with some other symbol in php?

To update the value with some other symbol in PHP, you can use the str_replace() function. This function replaces all occurrences of a specified value with another value in a string.

Here is an example:

1
2
3
4
5
6
7

$value = "Hello World!";
$symbol = "!";

// Update the value by replacing the symbol
$newValue = str_replace($symbol, "*", $value);

echo $newValue; // Output: Hello World*

In the above example, the str_replace() function replaces all occurrences of "!" with "*". The updated value is then stored in the $newValue variable and displayed using echo.
