Conditional Switch Statements in PHP

Conditional switch statements in PHP

I think you're searching for something like this (this is not exactly what you want or at least what I understand is your need).

switch (true) finds the cases which evaluate to a truthy value, and execute the code within until the first break; it encounters.

<?php

switch (true) {

case ($totaltime <= 1):
echo "That was fast!";
break;

case ($totaltime <= 5):
echo "Not fast!";
break;

case ($totaltime <= 10):
echo "That's slooooow";
break;
}

?>

PHP- Switch case statement with conditional switch

Switch only checks if the first condition is equal to the second, this way:

switch (CONDITION) {
    case CONDITION2:
        echo "CONDITION is equal to CONDITION2";
    break;
}

So you have to do it this way:

switch (true) {
    case $totaltime <= 1: #This checks if true (first condition) is equal to $totaltime <= 1 (second condition), so if $totaltime is <= 1 (true), is the same as checking true == true.
        echo "That was fast!";
    break;

    case $totaltime <= 5:
        echo "Not fast!";
    break;

    case $totaltime >= 10 && $totaltime<=13:
        echo "That's slooooow";
    break;
}

Instead of this i'll go for if-elseif statements. Is easier to understand at first sight:

if ($totaltime <= 1) {
    echo "That was fast!";
} elseif($totaltime <= 5) {
    echo "Not fast!";
} elseif($totaltime >= 10 && $totaltime<=13) {
    echo "That's slooooow";
}

PHP switch case more than one value in the case

The simplest and probably the best way performance-wise would be:

switch ($var2) {
    case 1:
    case 2:
       $var3 = 'Weekly';
       break;
    case 3:
       $var3 = 'Monthly';
       break;
    case 4:
    case 5:
       $var3 = 'Quarterly';
       break;
}

Also, possible for more complex situations:

switch ($var2) {
    case ($var2 == 1 || $var2 == 2):
        $var3 = 'Weekly';
        break;
    case 3:
        $var3 = 'Monthly';
        break;
    case ($var2 == 4 || $var2 == 5):
        $var3 = 'Quarterly';
        break;
}

In this scenario, $var2 must be set and can not be null or 0

How to get PHP switch case conditional statements code work properly on wordpress function.php

    $date = date('l');
    switch ($date) {
      case 'Sunday': $content = do_shortcode('[sunday_content]'); break;
      case 'Monday': $content = do_shortcode('[monday_content]'); break;
      case 'Tuesday': $content = do_shortcode('[tuesday_content]'); break;

      }
      return '<div class="daily_contant">'.$content.'</div>';

How can i avoid conditional statements or/and switch statements?

To avoid using conditionals you could use some sort of lookup to match the type to the field display I think.

Something like this perhaps:

$lookup = [
  "DVD" => ["field" => "size", "append" => "MB"],
  "Furniture" => ["field" => "dimentions", "append" => ""],
  "Book" => ["field" => "weight", "append" => "Kg"],
];

$LookupItem = $lookup[$product["product_type"]];
echo $product[$LookupItem["field"]].$LookupItem["append"];

SWITCH-statement two case with same condition and also different condition

For any variables that contain the same value why use a switch at all? Just define those variables before the switch statement. Use the switch statement only for variables that contains different values.

EDIT

In that case there is no reason why you can't use 2 switch statements, like this:

switch(strtolower($name))
{
case "dog":
    $pic = "/images/itscute.jpg";
    break;
case "cat":
    $pic = "/images/cat.jpg";
    break;
case "bird":
    $pic = "/images/bird.jpg";
    break;
}
switch(strtolower($name))
{
case "dog":
case "cat":
    $info = "four legs";
    break;
case "bird":
    $info = "two legs";
    break;
}

I do recommend that you use strtolower(), like my example shows, to avoid any case problems. You can use any number of switch statements as you need.
As for turning "dog" into "Dog's" just add the "'s" to the variable, like this:
$name = ucwords($name . "'s");
