Message:

I am very new to the regex patterns. I am developing one api which accepts the user value(status), based on the status it will perform the filtering operation upto this it's working fine.

Now what my requirement is I want to accept the value based on:

1. if the string contains multiple words it should be separated by space only not other symbols(/_) .

   
   



2. Both caps and small letters are allowed .

   
   

Valid scenarios:

1. Ready to dispatch


2. ReaDy To Dispatch


3. cancelled


4. CanceLled

Invalid scenarios:

1. Ready_to_dispatch

   
   



2. Ready-to-Dispatch

   
   

   $pattern=[a-zA-Z];
   
   $validation=preg_match($pattern,$request->status);
   
   if($validation){
   
     //My logic executes if it matches the pattern
   
   }

My Answer:
To write a regex pattern that accepts space in between words, you can use the following pattern:

php
$pattern = '/^[a-zA-Z ]+$/';


Explanation of the pattern:
- `^` asserts the start of the string
- `[a-zA-Z ]` matches any uppercase or lowercase letter or a space
- `+` specifies that the previous character (letter or space) can occur one or more times
- `$` asserts the end of the string

You can use this pattern in your code as follows:

php
$pattern = '/^[a-zA-Z ]+$/';
$validation = preg_match($pattern, $request->status);
if ($validation) {
// Your logic executes if it matches the pattern
}


This pattern will only allow strings that consist of letters (both uppercase and lowercase) and spaces. It will not allow other symbols like `/` or `_`.
