SQL query takes less time in MYSQL, take more in PHP application

Question

I have MYISAM table and i wrote a FULL-TEXT SQL query. When i execute this query, it takes < 0.53 seconds But when i execute this php+mysql application, it takes more than 1-2 minutes

Query:

select concat(first_name, ' ', last_name) as `cand_full_name`, email 
from resumes WHERE MATCH (thesis_text) AGAINST ('-java -j2ee -oracle -mysql -software' IN BOOLEAN MODE) 

Update 1:

I am using mysqli_query($this->dbconnection, $this->query) in query

Update 2:

PHP Code http://codepad.org/qufZBC16

Note :

I am not running any other sql query on this page.

Any Idea, why it's taking more time.

Answer 1

Its very likely to be a charset issue. Set the charset after connection to speed up query

I'm not sure what charset your data Is stored in
