Tring to insert varaiable into a DB with an apostrophe

[Square1]

Hi all:

I am trying to add this variable into a DB:

$promoter = $results2["Promoter"];

Problem is the variable has an apostrophe in it and I believe it is causing problems.

I thought addslashes was the remedy for this

$promoter = addslashes($results2["Promoter"]);

I tried

$promoter = str_replace("'","''",$promoter);

as well.

And I am using bound parameters.
Any direction appreciated!

Got it. Input error!
