I have a below string.

PHP, HTML, SQL

Want to convert it to

'PHP', 'HTML', 'SQL'

I tried to write a function to do it as below. If I print the function output it prints properly.

If same function output I use for SQL query as below I get warning.

Query: SELECT skillid FROM {resubmt_skills} WHERE resubmt_skills.skillname IN (%s)", $fSkill

Warning: SELECT skillid FROM resubmt_skills WHERE resubmt_skills.skillname IN (\'ITI\',\' PHP\'))) in C:\MyWeb6.20\wamp\www\livejobs1\sites\default\modules\resume_search\resume_search.module on line 140.

Looks it has extra forward slashes. How can I overcome this.

Thanks

Austin
