intagers only

Hey guys,

 

I need a function that can tell if any of the characters within var are a non integer.

 

basically its to verify that the value entered is a valid phone number

no no, i need a function that can tell if any of the character are not intagers.

 

so 2g4 would come back as false

but 224 would come back as true

[rhodesa]

is_int() will only return if the data type of the variable is INT....use is_numeric()

[Mark Baker]

Of course, is_numeric() will return true for '1.5e-2', '0xAB' and other similar variants, non of which remotely resembles a telephone number.

 

What was wrong with the original response pointing you to http://regexlib.com/REDetails.aspx?regexp_id=607

thanks guys

 

this is what i did

 

if(!is_numeric($_POST['phone1'])){$error=1;$phone=1;}

if(!is_numeric($_POST['phone2'])){$error=1;$phone=1;}

if(!is_numeric($_POST['phone3'])){$error=1;$phone=1;}

No problem, but regex is still better.

so 3.14159 qualifies as a valid phone number

 

And in an amazing coincidence, it's the phone number of the local pizza house.

ok i figured it all out

 

this is the new code that only allowes phone numbers, im 100% this works like it is suppost to

 

preg_match('/(^[0-9]*)/i', $_POST['ship_phone1'].$_POST['ship_phone2'].$_POST['ship_phone3'], $matches);
if($_POST['ship_phone1'].$_POST['ship_phone2'].$_POST['ship_phone3'] == $matches[0])
{
  if($_POST['ship_phone1']<="199")
  {$error .="Your Area Code cannot start with 1 and must be 3 digits long.<br>"."\n";}
  if($_POST['ship_phone2']<="199")
  {$error .="Your Phone Number cannot start with 1 and must be 3 digits long.<br>"."\n";}
  if(strlen($_POST['ship_phone3'])!="4")
  {
   $error .="Your Phone Number Must contain 10 digits.<br>"."\n";
  }
}
else
{
  $error .="Your Phone Number Can only contain characters 0-9.<br>"."\n";
}
