If variable equals value php [duplicate]

Answer 1

if ($type == 1) {$displayVar = "Bear";}

Example:

<form method="post" action="results.php">
How many horns does a unicorn have? <br />
<input type="text" name="inputField" id="inputField" /> <br />
<input type="submit" value="Submit" /> <br />
</form>

Results:

<?php 
$inputVar = $_POST["inputField"];
if ($inputVar == 1) {$answerVar = "correct";}
else $answerVar = "<strong>not correct</strong>";
?>
<?php 
echo "Your answer is " . $answerVar . "<br />";
?>

Answer 2

You are comparing, not assigning:

if ($type == 1){
  $type = "Bear"; 
}

You compare values with == or ===.

You assign values with =.

You could write less code to achieve the same result too, with a switch statement, or just a bunch of ifs without the elseifs.

if ($type == 1) $type = "Bear";
if ($type == 2) $type = "Cat";
if ($type == 3) $type = "Dog";

I would make a function for it, like this:

function get_species($type) {
    switch ($type):
        case 1: return 'Bear';
        case 2: return 'Cat';
        case 3: return 'Dog';
       default: return 'Jeff Atwood';
    endswitch;
}

$type = get_species($row['ttype']);

Answer 3

You are using == instead of =. It compares the variable to the new value. Use = to set the value.

if ($type == 1){
$type = "Bear";
} elseif ($type == 2){
$type = "Cat";
} elseif ($type == 3){
$type = "Dog";
}  

Answer 4

You're using == to assign values:

$type == bear;

Should be:

$type = bear;
