How to find word in a string?

[hongmei]

I have my query in $myquery. I need to find whether it contains "where" wording. if find "where", then I want to add "and" instead of "where".
I used
if (INSTR(1,$myquery,'where')>0){

}

I got fatal error. undefined instr() function.

Which syxtex should I use?

Thanks!

Hi,

Try to use substr_count()

by example:
print substr_count("This is a test", "is"); // prints out 2
