Replace text in quotation marks with placeholders

Hi everyone,

Happy New Year!!!

I’m looking for a way to replace the text in the quotation marks with placeholders.


$string = " = 'poodle' AND t.tree = 'oak' ";


$string = " = ? AND t.tree = ? ";

Does anyone know how this can be done?

Thank you!

I guess you need it to prepare a MySQL statement.
You can use mysqli classes for this purpose:
Suppose $stmt is an obect of calss mysqli_stmt, then you can prepare a query statement using $stmt->prepare, with question marks for placeholders, and then bind params using $stmt->bind_params.
There’s a wonderful example here.

Another way to use placeholders is to call functions such as printf and sprintf like in C.

$new_string = preg_replace("/'[^']*'/", '?', $string);
