I need a string which consists of some numbers, comma, undersocre, slash, hyphen and space.
I am almost ok. Here is my code so far.
$regex = '#^[0-9-_,/\s]+$#';
if(preg_match($regex, $string)){
return true;
} else {
return false;
}
But I want to contain at least 4 digit within 0 to 9.
for example, These are the values I want to valid:
09-12345678
123, 456, 789
12/ 34/ 56
These are the values I don't want to valid:
1,2
3/5/6
7-8-9
So, I tried like this.
$regex = '#^[0-9-_,/\s]{4,100}$#';
And,
$regex = '#^[0-9{4,100}-_,/\s]+$#';
But they are not true too. How can I do?
