What is the correct syntax to echo a variable within a PHP array?

Hey all,

I'm quite new to PHP and I'm currently working on an array. I have assigned a value to a variable and now I want to echo that variable within the array. However, I'm a bit confused about the correct syntax to do so. Can someone please guide me on how to echo a variable within a PHP array?

Thanks in advance!

Hello everyone,

When it comes to echoing a variable within a PHP array, another approach that you can take is by using the `sprintf()` function. This function allows for more complex string formatting and offers flexibility in manipulating variables within arrays. Here's an example:

$name = "John";
$age = 25;

$array = [
"info" => sprintf("Name: %s, Age: %d", $name, $age)

echo $array["info"]; // Outputs "Name: John, Age: 25"

In the code snippet above, I've defined the variables `$name` and `$age`. Then, within the array, I used `sprintf()` to format the string and insert the values of these variables using placeholders `%s` and `%d` respectively. This approach allows you to have more control over how the variables are displayed within the array.

Feel free to experiment with `sprintf()` and let me know if you have any questions!


Greetings everyone,

In order to echo a variable within a PHP array, you can make use of string interpolation. It's a more concise way of achieving the desired result. Here's an example:

$greeting = "Hey there";
$array = [
"message" => "$greeting, how are you doing?"

echo $array["message"]; // Outputs "Hey there, how are you doing?"

In this case, I assigned the value "Hey there" to the variable `$greeting` and directly interpolated it within the array declaration using double quotes. By enclosing the variable in curly braces `{}`, you can make sure it is recognized and properly displayed within the string.

Feel free to give it a try and let me know if you need further assistance!


Hey there,

To echo a variable within a PHP array, you simply need to concatenate the variable inside the array declaration using the dot (.) operator. Here's an example:

$variable = "Hello";
$array = array(
"message" => $variable . " World!"

echo $array["message"]; // Outputs "Hello World!"

In the above example, I assigned the value "Hello" to the variable `$variable` and then included it within the array declaration by concatenating it with the string " World!". The dot (.) operator is used for concatenation in PHP.

Hope this helps! Let me know if you have any further questions.
