I created a php script that uses a case and switch for dynamic content info. Everything works but I cannot get it to show the default page. I have searched all of stackoverflow and google and cannot seem to find out why my default in the switch wont load. I have tried other methods such as include('page.php');
<center><div class="dropdown">
<button class="dropbtn">TICKERS</button>
<div class="dropdown-content">
CRZ
FFT
GHG
GLH
IAN
IMH
IN
LAG
LIB
LXX
MDM
MJ
MMJ
NF
PUF
SL
SUN
TBP
THC
TNY
VGW
VP
VRT
</div>
</div></center>

<?php
if(isset($_GET['page']) && $_GET['page']!=""){
$page = "";

You write there in your if-condition:
if(isset($_GET['page']) && $_GET['page']!="")
So that means: If nothing is entered, don't go through the switch statement at all.
Either add an else-branch here or remove that if-clause.
This is not your question answer but is improved:
$allowed = array('fft','ghg','glh','ian','imh',
'in','lag','lib','lxx','mdm','mj',
'mmj','nf','puf','sl','sun','tbp',
'thc','tny','vgw','vp','vrt','crz' , //...
);
$page = 'csegainers';
if(isset($_GET['page']) && in_array($_GET['page'],$allowed)){
$page = $_GET['page'];
}
include($page . '.php');
The initial if won't let any blank $_GET['page'] pass by it. If you manually access a diferent value, say "document.php?page=example" the default case will fire normally.

I have checked the PHP source code and can not find the "require" function.
I only found a piece code relatives to it on main/main.c from line 976
switch (EG(current_execute_data)->opline->extended_value) {
case ZEND_EVAL:
function = "eval";
is_function = 1;
break;
case ZEND_INCLUDE:
function = "include";
is_function = 1;
break;
case ZEND_INCLUDE_ONCE:
function = "include_once";
is_function = 1;
break;
case ZEND_REQUIRE:
function = "require";
is_function = 1;
break;
case ZEND_REQUIRE_ONCE:
function = "require_once";
is_function = 1;
break;
default:
function = "Unknown";
}
Do you know which file defines the "function"?
Hy,
I got switch case inside function when but when i call it, i got error Undefined Variable and i don't know why (i use PHP 8)
private function getIDFromBrand() {
switch ($this->brand) {
case "Niky":
$id = 1;
break;
case "Pumo":
$id = 4;
break;
case "Coke":
if ($this->typecoke== 0) {
$id = 2;
} else {
if ($this->typecoke== 1) {
$id = 3;
}
}
break;
case "Tomato":
$id = 5;
break;
case "Riles":
$id = 6;
break;
case "TEST":
$id = 7;
break;
}
return $id; // Error Undefined variable $id
}
When i declare $id at the top of my function, like
$id = null
or
$id = 0
The switch doesn't update it, so it will return null or 0, it will return the declared value.
Your switch statement has no default branch, so if $this->brand is, say, "Stack Overflow", it will not run any of the statements, and $id will never be set.
See the PHP manual for the switch statement:
A special case is the default case. This case matches anything that wasn't matched by the other cases.
Similarly, if $this->brand is "Coke", but $this->typecoke is, say, 42, it will not match either of the conditions in that branch.
switch ($this->brand) {
case "Niky":
$id = 1;
break;
case "Pumo":
$id = 4;
break;
case "Coke":
if ($this->typecoke== 0) {
$id = 2;
} elseif ($this->typecoke== 1) {
$id = 3;
} else {
$id = -1; // WAS PREVIOUSLY NOT SET
}
break;
case "Tomato":
$id = 5;
break;
case "Riles":
$id = 6;
break;
case "TEST":
$id = 7;
break;
default:
$id = -1; // WAS PREVIOUSLY NOT SET
break;
}
I have this PHP function for changing color between 2 numbers:
function color_switch($number){
switch (true){
case $number == range(1 , 3):
$color = "progress-bar-danger";
break;
case $number == range(3 , 5):
$color = "progress-bar-warning";
break;
case $number == range(5 , 6):
$color = "progress-bar-default";
break;
case $number == range(6 , 8):
$color = "progress-bar-success";
break;
case $number == range(8, 10):
$color = "progress-bar-success";
break;
}
return $color;
}
But in action this function does not work for me. How should I fix this ?
You are comparing range() which is an array, and $number is integer, which is invalid,
Change your function something like,
function color_switch($number) {
switch ($number) { // switching the function argument
case $number <= 3 : // if less than three, execute case
$color = "progress-bar-danger";
break;
case $number <= 5 :
$color = "progress-bar-warning";
break;
case $number <= 6 :
$color = "progress-bar-default";
break;
case $number <= 8 :
$color = "progress-bar-success";
break;
case $number <= 10 :
$color = "progress-bar-success";
break;
}
return $color;
}
Your utilization of switch is incorrect and your utilization of range() is too.
Your parameter of switch should be the variable you evaluate.
Range() will return an array containing the range.
So the correct code is better :
function color_switch($number) {
switch ($number){
case in_array($number, range(1 , 3)):
$color = "progress-bar-danger";
break;
case in_array($number, range(3 , 5)):
$color = "progress-bar-warning";
break;
case in_array($number, range(5 , 6)):
$color = "progress-bar-default";
break;
case in_array($number, range(6 , 8)):
$color = "progress-bar-success";
break;
case in_array($number, range(8 , 10)):
$color = "progress-bar-success";
break;
}
return $color;
}
(sorry for my bad English writing). I've got a problem where I'm stuck with an if and else system that returns the level that you're.
Everything is good, if you have 20 clicks it will tell you that you're level 2, if you have 550 clicks it will tell you're level 6. But when you go up to 1500 clicks it needs to say level 9, but it will still say level 8.
My code:
$levelown = 'Level 1';
function ifElse() {
global $levelown;
global $arrayIP;
if($arrayIP['clicks'] >= 0 && $arrayIP['clicks'] <= 49)
{
$levelown = 'Level 2';
}
/* .... More if and elses with levels */
// This is the problem, this will keep telling me that I'm level 8.
elseif($arrayIP['clicks']>=3000)
{
$levelown = 'Level ' . floor(($score['clicks']/1000)+8);
}
and you are <strong><?php echo $levelown; ?></strong>
Thank you for helping!
The problem that i saw from your current code is that you have
elseif($arrayIP['clicks']>=3000)
{
$levelown = 'Level ' . floor(($score['clicks']/1000)+8);
}
which i think should be
elseif($arrayIP['clicks']>=3000)
{
$levelown = 'Level ' . floor(($arrayIP['clicks']/1000)+8);
}
since $score['clicks'] isn't present you will always end up with level 8
It's probably easier and more readable to make it a switch/case statement like so:
$highscore = $mysqli->query("SELECT id,name,clicks,ip,factory FROM highscore ORDER BY clicks DESC LIMIT 0,50 ");
$ipquery = $mysqli->query("SELECT id,name,clicks,ip,factory FROM highscore WHERE ip = '".$_SERVER['REMOTE_ADDR']."'");
$arrayIP = $ipquery->fetch_array();
$levelown = 1;
function ifElse() {
global $levelown;
global $arrayIP;
switch (true) {
case $arrayIP['click'] > 3000:
$levelown = floor(($arrayIP['click']/1000)+8);
break;
case $arrayIP['click']== 3000:
$levelown = 11;
break;
case $arrayIP['click'] >= 2000:
$levelown = 10;
break;
case $arrayIP['click'] >= 1500:
$levelown = 9;
break;
case $arrayIP['click'] >= 1000:
$levelown = 8;
break;
case $arrayIP['click'] >= 750:
$levelown = 7;
break;
case $arrayIP['click'] >= 500:
$levelown = 6;
break;
case $arrayIP['click'] >= 350:
$levelown = 5;
break;
case $arrayIP['click'] >= 200:
$levelown = 4;
break;
case $arrayIP['click'] >= 50:
$levelown = 3;
break;
case $arrayIP['click'] >= 0:
$levelown = 2;
break;
}
$levelown = "Level " . $levelown;
}
I´m trying to do some program which would transfer hexa do binary. Problem is in changing of A,B,C,..,F to 10,11,12,...,15 so i can work with them as with numbers. I made this function:
function odstran_pismena($pole)
{
$dlzka = count($pole);
for ($i = 0; $i< $dlzka; $i++)
switch ($pole[$i])
{
case 0: break;
case 1: break;
case 2: break;
case 3: break;
case 4: break;
case 5: break;
case 6: break;
case 7: break;
case 8: break;
case 9: break;
case ("A" || "a"): $pole[$i] = 10;
break;
case ("B" || "b"): $pole[$i] = 11;
break;
case ("C" || "c"): $pole[$i] = 12;
break;
case ("D" || "d"): $pole[$i] = 13;
break;
case ("E" || "e"): $pole[$i] = 14;
break;
case ("F" || "f"): $pole[$i] = 15;
break;
default: $pole[$i] = "ERROR";
break;
}
return $pole;
}
First i made array from string, and now i want to change letters to numbers.
I´m testing it with this string: $test = "AbCdEf2345";
I was expecting result 10 11 12 13 14 15 2 3 4 5 but all i have is 10 10 10 10 10 10 2 3 4 5
Am I doing some mystake?(Of course I am, but where?)
("A" || "a") evaluates to boolean value 'true', so all a to f will get caught by the case ("A" || "a" ) and result in 10.
Without using the hexdec() and with minimal change to your code:
function odstran_pismena($pole)
{
$dlzka = count($pole);
for ($i = 0; $i< $dlzka; $i++)
switch ($pole[$i])
{
case 0: break;
case 1: break;
case 2: break;
case 3: break;
case 4: break;
case 5: break;
case 6: break;
case 7: break;
case 8: break;
case 9: break;
case "A":
case "a": $pole[$i] = 10;
break;
case "B":
case "b": $pole[$i] = 11;
break;
case "C":
case "c": $pole[$i] = 12;
break;
case "D":
case "d": $pole[$i] = 13;
break;
case "E":
case "e": $pole[$i] = 14;
break;
case "F":
case "f": $pole[$i] = 15;
break;
default: $pole[$i] = "ERROR";
break;
}
return $pole;
}
When you have specified case ("A" || "a"): $pole[$i] = 10; it evaluates to true. So all your chars matched against true returns true. for 'case' conditions avoid using expressions. Use the static values your comparing such as
case "A":
case "a":
$pole[$i] = 10;
break;
An easy way to help you with that would be to use a strtolower:
switch(strtolower($pole[$i])) {
case "a" :...
break;
case "b": ...
break;
}
or simply, as the first line of your function:
$pole = strtolower($pole);
This way you won't have to bother with upper/lower casing.
You should use hexdec() and replace you whole for loop with:
for ($i = 0; $i< $dlzka; $i++)
{
$pole[$i] = hexdec($pole[$i]);
}
Note that you will receive a 0 for non-valid values so you might have to check for that separately if it can happen, using for example is_numeric on the original value.
