PHP Prepared Statements… Bind variable as numeric range in REGEXP?

$query = "SELECT * FROM `mytable` WHERE `file` REGEXP 'This string :var'";
$stmt = $dbh->prepare($query);
$stmt->bindValue(':var', 'exists');
$stmt->execute();

This throws error:

SQLSTATE[42000]: Syntax error or access violation

When I echo $query before the execute, I get:

SELECT * FROM `mytable` WHERE `file` REGEXP 'This string :var'

How the hell do you bind variables in a regexp?

Two things: You need to tell mysql what column you wish to apply REGEXP to and a placeholders can only be used where a value can appear (thanks to @Barmar). For example, if you wish to search col1 for 'This string :var' you need to do

SELECT * FROM `mytable` WHERE col1 REGEXP CONCAT('This string ', :var)
