check for number anywhere in a string

Question

$vari = "testing 245";
$numb = 0..9;

$numb_pos =  strpos($vari,$numb);
echo substr($vari,0,$numb_pos);

The $numb is numbers from 0 to 9 Where am I wrong here, all I need to echo is testing

Answer 1

Your code won't work as-is, as it'll fail if the number if the first character in the string. (You need to check $numb_pos !== false prior to the substr.)

Irrespective, if you just want to check for the existance of a number in a string, something like the following would probably be more efficient.

$digitMatched = preg_match('/\\d/im', $vari);

Answer 2

Use a regular expression to strip numeric characters from your string.

or, use a regular expression to find the first instance of one either way...

Answer 3

You want to cut out the numbers from a string?

$string = preg_replace('/(\d+)/', '', 'String with 1234 numbers');
