What are the differences between the PHP and ColdFusion languages in terms of syntax and functionality?

PHP and ColdFusion are both server-side scripting languages, but they have differences in syntax and functionality. PHP uses a C-style syntax with curly braces {} to denote code blocks, while ColdFusion uses tags like <cfif> and <cfloop> to perform conditional statements and loops. In terms of functionality, PHP is open-source and runs on multiple platforms, while ColdFusion is a commercial product developed by Adobe primarily for web development.

// PHP code snippet
&lt;?php
  $num1 = 10;
  $num2 = 5;
  $sum = $num1 + $num2;
  echo &quot;The sum of $num1 and $num2 is: $sum&quot;;
