php for loop variable names

Question

i got a code of 100-200 rules for making a table. but the whole time is happening the same. i got a variable $xm3, then i make a column . next row, i got $xm2 and make column. n

Answer 1

It is not fully clear what you are asking, but you can do

$xm = 'xm3';
$$xm // same as $xm3

in PHP, so you can loop through variables with similar names. (Which does not mean you should. Using an array is usually a superior alternative.)
