In PHP, Removing first element in CSV String

Question

I'm simply looking to take the first csv out of a string, using PHP. Here are a few examples:

"Sea Bass, Floured Or Breaded, Fried" => "Floured Or Breaded, Fried"
"Tuna, Fresh, Baked Or Broiled" => "Fresh, Baked Or Broiled"
"Croaker, Breaded Or Battered, Baked" => "Breaded Or Battered, Baked"

And so on...

Thank you.

Sorry but can you give more information, not sure what you mean. — PHPology

Do you already have code that loads the CSV file into memory? If so, would you please post the relevant portion? — Ben Gribaudo

Show the CSV data, because what this is, isn't separating the two elements, which means you want to modify data inside a csv element rather than remove an element. — Incognito

As Ben says, how are you populating your string.... if it is from a file, then PHP's fgetcsv() function can simplify things for you — Mark Baker

You can try this:

$csvArray = explode(",", $csv);
array_shift($csvArray);
$newCsv = implode(",", $csvArray);

You don't need to (and should not ever) pass an array (or anything, really) by reference to a built-in function unless the function expressly requests a reference. Besides being counter-intuitively slow, it's previously been a security risk in the PHP core (check out the "interruption" bugs...)

Won't work if any of the values actually contain a comma, whereas the built in CSV handling functions can handle this

array_shift does request a reference.

@Mark Baker: yea true, but that was just a quick solution based on examples he posted.

Charles Over a year ago

array_shift works with a reference, but you do not need to expressly create a reference to make it work. What you'd done is called "call-time pass-by-reference", and is considered such a bad practice that they added an error message just to tell people to stop doing it.

I suggest using str_getcsv or something similar that parses csv, this will take into account any quotation marks and commas in the CSV string. after that you can just array_shift
