Question

Is there a way in PHP to only echo the integers from a variable?

For example say I had this piece of code:

$variable = "something123";

How would I echo out only the “123”?

Answer 1

You should use a regular expression for this.

preg_match('/\d+/', $variable, $match);
echo $match[0];

The $match variable is filled with the first numerical part of the string you pass to the preg_match function.

\d+ means “1 or more digits”
