PHP 8.1 deprecated passing null to parameter #3 when using str_replace(). str_repace() is commonly used among developers to replace the one word with another in the string.
Example:
$value = str_replace( "[", "{", $value );
which replaces [
with {
in the string $value
.
Since 8.1, if the $value
is null, the above deprecated message will be thrown.
Fix:
Make sure the 3rd parameter is not null.
or,
$value = $value ? str_replace( "[", "{", $value ) : '';
I hope this clarifies! In case you don’t already know, PHP 8.1 also deprecated passing null to parameter #1 of type string in strpos()
[Fix] str_replace(): Passing null to parameter #3 ($subject) of type array|string is deprecated
Good, this is work in my script
Thanks a lot
