Question

I have this strings. i want to remove the "0002." but it also remove the 22. How will i remove the leading numbers and the dot(.) then stop removing any numbers after?

$title = "0002.22 Greatest Voices In The Business (Current Female Singers Only)";
$words = preg_replace('/[0-9]+./', '', $title );

output:

Greatest Voices In The Business (Current Female Singers Only)

expected output:

Answer 1

So, you need to remove all numbers from start of the string till the dot ? Use ^ for "start of string"

$title = "0002.22 Greatest Voices In The Business (Current Female Singers Only)";
$words = preg_replace('/^[0-9]+\./', '', $title );

If u need to remove any number followed by dot, your code is correct, except that dot is special character and need to be escaped .

$title = "0002.22 Greatest Voices In The Business (Current Female Singers Only)";
$words = preg_replace('/[0-9]+\./', '', $title );
