mysql automatically cast strings to integer

Question

I\'ve just noticed that if I do a MySQL request like this one:

SELECT 1 FROM myTable WHERE id = \'asdf\'

Then the string \'asdf\' is casted

Answer 1

Since pdo prepared statements binding with correct types will not raise any error (except if mysql strict mode is enabled), your only choice is to ensure and control the types of your variables within your php to "correct" the permissivity of these languages.
