String and variable concatenation in php

问题

I am new to PHP and I want to concatenate a string with a variable without any space. I am using a variable $var and a string which is given below.

$var   // This is variable
"Name\branch" //This is String

I want to concatenate the string and the variable without any space. I am using code like this:

$var2 = "Name\Branch\ $var" 

But a space is created between them.

回答1:

Space is there, because you entered it ;)

Use examples:

$var2 = "Name\Branch\\$var";
$var2 = "Name\Branch\\" . $var;
$var2 = 'Name\Branch\\' . $var;
$var2 = "Name\Branch\\{$var}";
$var2 = trim("Name\Branch\ ") . $var;

回答2:

Use . for concatenations:

$var2 = "Name\\branch\\".$var;

Refer to the PHP manual.

回答3:

$var1 = 'text';
$var2 = "Name\branch\".$var1;

回答4:

Please try below code : concatenation $var and $str using dot(.)

 $var = 'variable';
 $newvar = "Name\\Branch\\".$var

You can use { } to use variable's value in a string.

$result = "Name\Branch\\{$var}";

回答6:

$var2 = "Name\Branch\".$var;
