如何使用cancatinating为我的php字符串变量添加括号？

I'm using PHP version 5.5.12. Why is my browser putting a <br /> when I am concatinating strings?

Let's say I want to add brackets to a variable to make it into an array variable like this:

$strName = $plyrMtchResult.'[]';
echo $strName;

Assuming $plyrMtchResult is "Hello World", my browser show this when I view the page via view page source:

'Hello World' <br />'.'[]'

What I would like to see is: $strName[] in my page source. How can I add brackets to my variable using concatinating?

Thanks for helping..

Is this what you are trying to do

$withbrackets = '[' . $strName . ']';

I used: $strName=$plyrMtchResult.'['.']'; $strName=preg_replace( "'
'", "", $strName ); echo $strName;

Got it...I use :

$strName=$plyrMtchResult.'['.']'; 
$strName=preg_replace( "' <br />'", "", $strName ); 
echo $strName;
