php - Function returns lots of notices -

First of all, my skill level is the best, a hobbit - I'm new at all, if not all of you.

I am trying to create a function that is a & lt; Br / & gt; will return if no parameter / value is returned, many & lt; Br / & gt; tag is equal to $ num

I am trying to create this function:

a) How to create a function

b) I & lt; Br / & gt;

C) I hate to type, this is the idea of ​​the function that came with interest to me.

So, ideally, in my code, if type getBrT () , this is a single return the tag, if I type << code> getBrT (1) , it also has a single & gt; return the tag, but if type getBrT (5) this five & lt; Br / & gt; return the tag.

This is not working because I hope that when I type getBrT () . Do I always have a price to flatten? Am I trying to not be possible within PHP's obligations?

Here is the function I have created:

  function getBrT2 ($ num) {// If the number is equal to 'nothing', 1 break - repeatedly Easy to call / Type the code ($ num = '') {echo '& lt; Br / '; } Else {// If the number is equal to 'some', breaks equal value $ i = 0; // Initial Counter ($ i & lt; $ num) {echo '& lt; Br / & gt; '; // sal = i ++;}}}    
 
 
 to ensure that This function does not give any value to the function, a default value is set.  
  function getBrT2 ($ num = 1) {// default value 1 $ num = (int) $ num; // if the number is negative ($ num & lt; 1) {// if the number is negative 0 or negative then it would be numerically numerator of 1 $ num = 1; } Return str_repeat ('& lt; br / & gt;', $ num); // many & lt; Br / & gt; As requested, echo getBrT2 (1); // prints "
" Echo getBrT2 (5); // print out "
 
 
 
 
 
 
" Echo getBrT2 (''); // prints "
" Echo getBrT2 ('hello'); // prints "
"   
 I made some improvements to your function.  
 
 In addition to the default value, I put the value passed to an integer, because we need to work with it. Any string value that does not begin with a number will be converted to  0 .  
 Then we check that  is $ num  is  0  or if a negative number, then we make it  1  .  
 Then we need as many as  str_repeat ()  as many  & lt; Br / & gt;  tags  
 Then we return that string, so that it is echoed.
