Problem in single quote

[eluser]Tamilmani[/eluser]
I have tried those things

For Example:

$name = "Mc'Donald";
$slashName = addslashes($t); // output- 'Mc\'Donald'
insert into user(user_name)values('$slashName');

when i tried to run the above query.

Getting below error message.

Msg 102, Level 15, State 1, Line 1
Incorrect syntax near 'Donald'.
Msg 105, Level 15, State 1, Line 1
Unclosed quotation mark after the character string ')
'.
