Need help with preg_match

[fifin04]

Hi there..

 

I really need help with my ugly regex code because it still can't diferrentiate string and string contain only numbers ok here the scenario;

 

All the string must meet this 3 conditions

 

1.String contain only alpha,space and dot

2.String contain only alphanumeric,space and dot

3.String contain only numbers

 

so here's my attempt code so far

 

$testStringArray = array("abc. bc. def83","abc. bc.","123","567","fdg. qwe.","dfg. rtu. hu8");

//so i start filter testing here

$total = count($testStringArray);

for($i=0;$i<$total;$i++){
   if(preg_match('/[a-zA-Z.\...\\s.]+$/',$testStringArray[$i])){
            echo $i." : ".$testStringArray[$i]." contain only alpha,dot,space";
  }else if(preg_match('/^[a-zA-Z0-9.\...\\s.]+$/i/',$testStringArray[$i])){
           echo $i." : ".$testStringArray[$i]." contain only alpha,dot,numbers,space";
  }else if(preg_match('/^[0-9]/',$testStringArray[$i])){
      echo $i." : ".$testStringArray[$i]." contain only numbers";
  }

}

 

Current output:

 

 

contain only alpha,dot,numbers,space

contain only alpha,dot,space

contain only alpha,dot,numbers,space-->it seems the regex not wokr here

contain only alpha,dot,numbers,space-->it seems the regex not wokr here

contain only alpha,dot,space

contain only alpha,dot,numbers,space

 

suppose to :

 

contain only alpha,dot,numbers,space

contain only alpha,dot,space

contain only numbers--->shoud be numbers only

contain only numbers--->shoud be numbers only

contain only alpha,dot,space

contain only alpha,dot,numbers,space

 

So i really need help with it....thanks in advance guys...

I think it fails because the order of 'if's

 

for example take string "123"

U aks "Does this string contains only alpha space or dot characters"?

NO

Then u ask "Does this string contains alpha numbers space or dot chars only"?

YES cuz "123" realy cointains numbers

And since second's 'IF' answer was YES u never will reach third 'IF'

 

so try do something like:

 

if('/^[0-9]+$/im') //only numbers
{
}
else if ('/^[a-z\\s\\.]+$/im') //alpha space dot
{
}
else if('/^[a-z0-9\\s\\.]+$/im') //alpha numbers space dor
{
}
