For loop to extract and execute data from a list

Question

0.00/5 (No votes)

I need to do a loop to extract every single "sample ID" from the list and execute the code below.

The "Sample IDs" contain all the ID values (ex: GD6871) from 1 to N, where N is the size of the list in terms of the number of "Sample IDs" present.

The ID values are on another page, so it must be able to get these values with ($ _GET ['idList']); , unpack them to be able to read them here.

What I have tried:

PHP

//The given code
$sampleIDList = htmlspecialchars($_GET['idList']);

for i = 1 to N ...   //Part of the click is what I need.

...

 
$sampleID = $sampleIDList(i);




//Instruction of the page from where I have to import the IDs automatically.

<td><?=$test->sampleID?><br>
                                
<?=$reportStatusDisplay?>
</td>

What values are being passed in to $_GET['idList']? Is it a string value delimited by something like commas or new-lines?

It's an array of strings, actually, an array of values that I've concatenated into on the other page.

You mention you've concatenated together the values into the $_GET['idList'] value so what you'll need to do is split the values again back into an array before you can iterate over them.

You can split using the PHP: explode - Manual[^] function, which will take the string value and split it based on a delimiter.

For example, if your string has been concatenated with a comma as the delimiter then you'd need to explode on that:

PHP

$idList = $_GET['idList'];
$idArray = explode(",", $idList);

foreach ($idArray as $id) {
  $id = htmlspecialchars($id);
}
