I need a php regex expression to catch a pattern number/x/number strings.
Examples of strings that would be valid:
"100x100"
"350x200"
"1x2000"
... etc
Examples of strings that would NOT be valid:
"100"
"absx200"
"x35"
... etc
I am trying:
/^[\w-_.]*$/
But it is not working. Please help

\d x\d
Should do the trick.
\d is for digits and means 1 or more. x means x and the rest is a repeat of the first two commands. Basically 1 or more digit followed by an x followed by one or more digits.
