What will be the output of the following PHP code ?< ?phpone = 1;two = 2;three = 3;four = 4;echo "one / two + three / four";?>

The provided PHP code has a few issues that need to be addressed. Here's the analysis of the code:

Code Correction

1. Variable Declaration:

   • The variables are not correctly formatted. In PHP, variable names must begin with a dollar sign ($).
   • Therefore, one, two, three, and four should be declared as $one, $two, $three, and $four.

2. Output Syntax:

   • The echo statement is outputting a string rather than the result of the calculations. To output the result of the arithmetic operations, it should not be enclosed in quotes.

Corrected Code

<?php
$one = 1;
$two = 2;
$three = 3;
$four = 4;
echo $one / $two + $three / $four;
?>

Output Calculation

1. Calculate one / two: $\frac{1}{2} = 0.5$

2. Calculate three / four: $\frac{3}{4} = 0.75$

3. Sum the results: $0.5 + 0.75 = 1.25$

Final Answer

The output of the corrected PHP code will be 1.25.
