To read all entries from a CSV file, use the following code:

$csvReader = new CSVReader();

// CSV Reader Options
$csvReader->setFile("path/to/file.csv")
          ->setHeader(false)
          ->setDelimiter(";")
          ->setMaxLineLength(null)
          ->read();

// Get the CSV Data
$data = $csvReader->getData();

You can use the setHeader(bool $header) method to specify whether the CSV file contains a header or not. If the method is called with true as parameter, the first row will be skipped and not returned in the $data array. By default, no header is assumed.

Instead of explicitly setting the delimiter, you can also use the detectDelimiter() method. This method uses the first line of the CSV file to detect which character of ,, ;, \t or | occurs most often and uses it as the delimiter.

Warning: If the first line of the CSV file contains ,, ;, \t or | more often than the actual delimiter, the method will not detect the correct delimiter.

As an example, if the CSV file looks like this:

name;age;city
Alice;25;New York
Bob;30;London
Charlie;20;Berlin
David;35;Paris
Frank;40;Tokyo

the returned $data array would be:

[
    [
        "name",
        "age",
        "city"
    ],
    [
        "Alice",
        "25",
        "New York"
    ],
    [
        "Bob",
        "30",
        "London"
    ],
    [
        "Charlie",
        "20",
        "Berlin"
    ],
    [
        "David",
        "35",
        "Paris"
    ],
    [
        "Frank",
        "40",
        "Tokyo"
    ]
]

If you'd call the setHeader(bool $header) method with true as parameter, the contents of the first row will be omitted from the $data array:

[
    [
        "Alice",
        "25",
        "New York"
    ],
    [
        "Bob",
        "30",
        "London"
    ],
    [
        "Charlie",
        "20",
        "Berlin"
    ],
    [
        "David",
        "35",
        "Paris"
    ],
    [
        "Frank",
        "40",
        "Tokyo"
    ]
]
