$index as a parameter : multiple if statement issue - function

Question

Please take a look at this function :
function my_func($index_bis) {
if (!is_int($index_bis) || $index_bis > 5 || $index_bis < 0) return;
elseif ($index_bis = 5) : echo 'This';
elseif ($index_bis = 1) : echo 'That';
endif;
}
What's wrong with this? I actually can't understand where is the mistake...
Thank you for your help.

Answer 1

What is this? PHP?
And what are you attempting to do?
How about this:
function my_func($index_bis) {
if (!is_int($index_bis) || $index_bis > 5 || $index_bis < 0){
$str = $index_bis;
}
elseif ($index_bis == 5) {
$str='This';
}
elseif ($index_bis == 1) {
$str='That';
}
return $str;
}
It's pretty atypical to put anything after "return"; and I think "return" stops the function, effectively.
Edit: FOREACH method.
If you are building html from two related variables, FOREACH is a great method for handling them, as you can set a data "key" and "value" for each item in the array.
By default, the "key" in PHP is assigned a number, starting from 0 and progressing through increasing integers. You have the option of naming these keys, instead of using the PHP-assigned default.
So consider setting up your array as such:
$newArray = (
'tab name' => 'label name',
'apples' => 'red',
'oranges' => 'orange',
);
Wherein the item to the left of the "=>" is always the key, and the item to the right is always the value.
Then, you can add more elements to this array in your code by using this line:
$newArray['bananas'] = 'yellow';
Note the key (tab) name, with square brackets (because it is the key name) and single quotes (because it is a string).
Now that you have an array, you can "walk" it using a FOREACH loop and echoing the html. Here is the code:
foreach($newArray as $key => $value) {
echo "<tab>$key</tab> : ";
echo "<label>$value</label>
echo "<br /";
}
This will output the html below:
<tab>tab name</tab> : <label>label name</label><br />
<tab>apples</tab> : <label>red</label><br />
<tab>oranges</tab> : <label>orange</label><br />
<tab>bananas</tab> : <label>yellow</label><br />
Very useful. Have fun!
Note: There are likely better ways to do this, but I'm sharing this one as a simple solution. And also, because you shouldn't go further without understanding both FOREACH and simple arrays.
Note: If you want to incorporate more than two variables, you will need a more complex data structure. In PHP, these are called "multidimensional arrays". Give it a read. Beyond that, there are still more methods for handling data (ie. "objects").
