How Can I Use a Conditional Statement within a PHP `echo` Statement to Set an Attribute?

If-Else Statement within Echo Expression

In PHP, it is generally not possible to include an if block directly within an echo statement. However, there is an alternative approach that can be used to achieve the desired result.

In your code, you wish to set the 'selected' attribute for the 'United States' option in a select element. To accomplish this, you can employ the ternary operator, which provides a condensed form of the if-else statement:

echo '<option value="'.$value.'" '.(($value=='United States')?'selected="selected"':"").'>'.$value.'</option>';

Here, the ternary operator is used to evaluate whether $value is equal to 'United States'. If true, it adds the 'selected="selected"' attribute to the option tag; otherwise, it includes an empty string. This allows you to set the selected option without using an if-else block within the echo statement.
