Simple PHP IF/ELSE code not working properly with html markup [duplicate]

  • The 3 different equals

    5 answers




I have started to learn some basic PHP. So far everything worked perfectly until I tried to run some IF/ELSE statements embedded into the markup as you can see in the snipet bellow:






<?php 

$msg = 0;

echo $msg;

?>



<!DOCTYPE html>

<html lang="en">

<head>

    <title>Test</title>

</head>

<body>

    <?php if ($msg = 5){ ?>

        <h1>5</h1>

    <?php } elseif ($msg = 0) { ?>

        <h1> 0 </h1>

    <?php } else { ?>

        <h1>Whatever</h1>

    <?php } ?>

</body>

</html>





The result is always the first if statement, even if it doesn't meet the condition. In this case the result is:



0



5



Tried everything I knew and searched a lot without any results. What am I doing wrong here?

    YOU missed = in your if condition. it should be ==.

This is a simple syntax error, it needs to be:



<?php 

$msg = 0;

echo $msg;

?>



<!DOCTYPE html>

<html lang="en">

<head>

    <title>Test</title>

</head>

<body>

    <?php if ($msg == 5){ ?>

        <h1>5</h1>

    <?php } elseif ($msg == 0) { ?>

        <h1> 0 </h1>

    <?php } else { ?>

        <h1>Whatever</h1>

    <?php } ?>

</body>

</html>


Notice the == which compares things vs. = which sets things.

    The = sign is for assignment; in order to do a comparison you need to use ==:



    <?php if ($msg == 5){ ?>

      The problem is in the condition -> ($msg = 5)
      It should be ==
      ($msg == 5) instead of ($msg = 5).



      When you are comparing two values you need to use double equal sign not single.
      Single means you are assigning value to the variable.



      Don'g give up!!



      Good luck!

                      The problem is in the condition -> ($msg = 5)
                      It should be ==
                      ($msg == 5) instead of ($msg = 5).



                      When you are comparing two values you need to use double equal sign not single.
                      Single means you are assigning value to the variable.



                      Don'g give up!!



                      Good luck!
