Question

I have table called “location” with a field “area”. This field can contain various type of values. Example:

“1.0/5.”, “32.22/29.”,
“.0/2.”, “6.4/15.”, “nothing” etc

I want create a regular expression that selectes only the the first number from this field and adds 1 to it.

So using the example above, the update will result in:

“2”, “33”, “1”, “7”.

Hopefully that makes sense.

Answer 1

Try this:

preg_replace("/^[^0-9]*([0-9]+).*$/e","$1+1", $input);

.. unless ofcourse you want to do it straight in the MySQL query
