There are several ways to concatenate two strings together.

Use the concatenation operator . (and .=)

In PHP . is the concatenation operator which returns the concatenation of its right and left arguments

$data1 = "the color is";
$data2 = "red";
$result = $data1 . ' ' . $data2;

If you want to append a string to another string you would use the .= operator:

$data1 = "the color is ";
$data1 .= "red"

Complex (curly) syntax / double quotes strings

In PHP variables contained in double quoted strings are interpolated (i.e. their values are "swapped out" for the variable). This means you can place the variables in place of the strings and just put a space in between them. The curly braces make it clear where the variables are.

$result = "{$data1} {$data2}";

Note: this will also work without the braces in your case:

$result = "$data1 $data2";

You can also concatenate array values inside a string :

$arr1 = ['val' => 'This is a'];
$arr2 = ['val' => 'test'];
$variable = "{$arr1['val']} {$arr2['val']}";

Use sprintf() or printf()

sprintf() allows us to format strings using powerful formatting options. It is overkill for such simple concatenation but it handy when you have a complex string and/or want to do some formatting of the data as well.

$result = sprintf("%s %s", $data1, $data2);

printf() does the same thing but will immediately display the output.

printf("%s %s", $data1, $data2);
// same as
$result = sprintf("%s %s", $data1, $data2);
echo $result;

Heredoc

Heredocs can also be used to combine variables into a string.

$result= <<<EOT
$data1 $data2
EOT;

Use a , with echo()

This only works when echoing out content and not assigning to a variable. But you can use a comma to separate a list of expressions for PHP to echo out and use a string with one blank space as one of those expressions:

echo $data1, ' ', $data2;

combine two strings together in PHP     result    data1          data2

I believe the most performant way is    data1    the color is    data2    red    result    data1          data2    If you want to implement localisation  you may do something like this    translationText    the color is  s    translationRed     red    result   sprintf  translationText   translationRed     It s a bit slower  but it does not assume grammar rules

I am not exactly clear with what your requirements are but basically you could seperately define the two variables and thereafter combine them together    data1  The colour is     data2  red     result  data1  data2    By doing so you can even declare  data2 as a global level so you could change its value during execution  for instance it could obtain the answer  red  from a checkbox

A period is used to concatenate strings  Simple example to turn two string variables into a single variable    full    part1    part2    In your example  you d want to do    result    data1          data2    You ll notice I added a string of one space between the two variables  This is because your original  data1 did not end with a space  If you had combined them without it  your  result variable would end up looking like the color isred

User · Answer

result    data1    data2    This is called string concatenation  Your example lacks a space though  so for that specifically  you would need    result    data1          data2

User · Answer

Concatenate them with the   operator    result    data1          data2    Or use string interpolation    result     data1  data2

User · Answer
