This simple loop, the inside of the variable exactly how to write it? It's simple, I'm a novice, I don't know how to write

In this simple loop, how do the variables in the inside write? It's simple, I'm a novice, I don't know how to write.
for ($k =1; $k <4; $k + +) {

$blName _. $k = ' Hello '. $k;

｝

I want to put this $blname_1, the following number 1 is the increment effect, that is: $blName _1, $blName _2, $blName _3, with variable loop instead, how to write it?

------Solution--------------------
for ($k =1; $k <4; $k + +) {
$varname = ' blname_ '. $k;
${$varname} = ' Hello '. $k;
｝
Because $varname = ' blname_1 ' so $ $varname = $blName _1;
Generally not, this should be done with an array of

   PHP Code
   
   
for ($k =1; $k <4; $k + +) {${"blname_{$k}"} = ' Hello '. $k; 
------Solution--------------------
 
     
     

      
       PHP code 
      
      
 $arr =array (); for ($k =1; $k <4; $k + +) {Array_push ($arr, ' hello '. $k);} List ($blName _1, $blName _2, $blName _3) = $arr; 
------Solution--------------------
 $var = Array (); 
 for ($k =1; $k <4; $k + +) {
 $var [] = ' hello '. $k; 
 } 
 Print_r ($var); 
    Output 
 Array (
 [0] = ' Hello 1 '; 
 [1] = ' Hello 2 '; 
 [2] = ' Hello 3 '; 
) 
//Take the value $var [1] and the value is ' Hello 2 '.

------solution--------------------
 ${"Blname$k" } = ' Hello '. $k; 
 
 PHP recommended syntax 
 $varname = ' blname '; 
 for ($k =1; $k <4; $k + +) {
 $blName = $varname. $k; 
 $ $blName = ' Hello '. $k; 
} 
 
 What do you mean by enclosing a variable with {}? 
 ${$varname} 
 and ${"blname_{$k}"} 
 
 curly braces treat the enclosed part as a whole
