I have a code that needs to read in a file and has a parameter file. I need to know how to put in <=,<,=,>=,> operators that will be in my parameter file.
I beleive that it needs to go in this line:
$search=explode(':',strtoupper($params[0]));
but not sure if it will look like this
$search=explode('<','<=','>','>=','=',strtoupper($params[0]));
