I want to upload a csv file with php. After the file is uploaded, I want to display the data of the CSV file. I would like an example how to accomplish this task.

This can be done in a much simpler manner now.
$tmpName = $_FILES['csv']['tmp_name'];
$csvAsArray = array_map('str_getcsv', file($tmpName));
This will return you a parsed array of your CSV data. Then you can just loop through it using a foreach statement.

explode(<delimiter>, $csv) you can separate each field and have an array of fields inside each element of the CSV array.untested but should give you the idea. the view:
<form action="upload.php" method="post" enctype="multipart/form-data">
<input type="file" name="csv" value="" />
<input type="submit" name="submit" value="Save" /></form>
upload.php controller:
$csv = array();
// check there are no errors
if($_FILES['csv']['error'] == 0){
    $name = $_FILES['csv']['name'];
    $ext = strtolower(end(explode('.', $_FILES['csv']['name'])));
    $type = $_FILES['csv']['type'];
    $tmpName = $_FILES['csv']['tmp_name'];
    // check the file is a csv
    if($ext === 'csv'){
        if(($handle = fopen($tmpName, 'r')) !== FALSE) {
            // necessary if a large csv file
            set_time_limit(0);
            $row = 0;
            while(($data = fgetcsv($handle, 1000, ',')) !== FALSE) {
                // number of fields in the csv
                $col_count = count($data);
                // get the values from the csv
                $csv[$row]['col1'] = $data[0];
                $csv[$row]['col2'] = $data[1];
                // inc the row
                $row++;
            }
            fclose($handle);
        }
    }
}

$csv[$row]['row1'] = $data[0]; is misleading, it should be $csv[$row]['column1'] = $data[0];. In any case, a better solution is just to use $csv[$row]=$data and make a multi-dimensional array with the whole file.Although you could easily find a tutorial how to handle file uploads with php, and there are functions (manual) to handle CSVs, I will post some code because just a few days ago I worked on a project, including a bit of code you could use...
HTML:
<table width="600">
<form action="<?php echo $_SERVER["PHP_SELF"]; ?>" method="post" enctype="multipart/form-data">
<tr>
<td width="20%">Select file</td>
<td width="80%"><input type="file" name="file" id="file" /></td>
</tr>
<tr>
<td>Submit</td>
<td><input type="submit" name="submit" /></td>
</tr>
</form>
</table>
PHP:
if ( isset($_POST["submit"]) ) {
   if ( isset($_FILES["file"])) {
            //if there was an error uploading the file
        if ($_FILES["file"]["error"] > 0) {
            echo "Return Code: " . $_FILES["file"]["error"] . "<br />";
        }
        else {
                 //Print file details
             echo "Upload: " . $_FILES["file"]["name"] . "<br />";
             echo "Type: " . $_FILES["file"]["type"] . "<br />";
             echo "Size: " . ($_FILES["file"]["size"] / 1024) . " Kb<br />";
             echo "Temp file: " . $_FILES["file"]["tmp_name"] . "<br />";
                 //if file already exists
             if (file_exists("upload/" . $_FILES["file"]["name"])) {
            echo $_FILES["file"]["name"] . " already exists. ";
             }
             else {
                    //Store file in directory "upload" with the name of "uploaded_file.txt"
            $storagename = "uploaded_file.txt";
            move_uploaded_file($_FILES["file"]["tmp_name"], "upload/" . $storagename);
            echo "Stored in: " . "upload/" . $_FILES["file"]["name"] . "<br />";
            }
        }
     } else {
             echo "No file selected <br />";
     }
}
I know there must be an easier way to do this, but I read the CSV file and store the single cells of every record in an two dimensional array.
if ( isset($storagename) && $file = fopen( "upload/" . $storagename , r ) ) {
    echo "File opened.<br />";
    $firstline = fgets ($file, 4096 );
        //Gets the number of fields, in CSV-files the names of the fields are mostly given in the first line
    $num = strlen($firstline) - strlen(str_replace(";", "", $firstline));
        //save the different fields of the firstline in an array called fields
    $fields = array();
    $fields = explode( ";", $firstline, ($num+1) );
    $line = array();
    $i = 0;
        //CSV: one line is one record and the cells/fields are seperated by ";"
        //so $dsatz is an two dimensional array saving the records like this: $dsatz[number of record][number of cell]
    while ( $line[$i] = fgets ($file, 4096) ) {
        $dsatz[$i] = array();
        $dsatz[$i] = explode( ";", $line[$i], ($num+1) );
        $i++;
    }
        echo "<table>";
        echo "<tr>";
    for ( $k = 0; $k != ($num+1); $k++ ) {
        echo "<td>" . $fields[$k] . "</td>";
    }
        echo "</tr>";
    foreach ($dsatz as $key => $number) {
                //new table row for every record
        echo "<tr>";
        foreach ($number as $k => $content) {
                        //new table cell for every field of the record
            echo "<td>" . $content . "</td>";
        }
    }
    echo "</table>";
}
So I hope this will help, it is just a small snippet of code and I have not tested it, because I used it slightly different. The comments should explain everything.

$content obtained from the inner foreach loop in the text-fields? I am trying to do this here : stackoverflow.com/questions/14536221/…I have created below snippet with the help of @Thomas Clowes answer
$tmpName = $_FILES['csv']['tmp_name'];
$csv_data = array_map('str_getcsv', file($tmpName));
array_walk($csv_data , function(&$x) use ($csv_data) {
  $x = array_combine($csv_data[0], $x);
});
/** 
*
* array_shift = remove first value of array 
* in csv file header was the first value
* 
*/
array_shift($csv_data);
// Print Result Data
echo '<pre/>';
print_r($csv_data);    
It will get result like below
 Array
(
   [0] => Array
    (
        
        [make] => Audi
        [model] => S4
        [grade] => 
        [chassis] => WAUZZZ8K9DA076529
        [year] => 2012
        [kms] => 127000
        [color] => White
        [doors] => 4
        [cc] => 3000
        [engineno] => 
        [trans] => FAT
        [fueltype] => P
        [condition] => 4            
        [price] => 15753
        
    )
)

You want the handling file uploads section of the PHP manual, and you would also do well to look at fgetcsv() and explode().

I feel str_getcsv — Parse a CSV string into an array is the best option for you.
- You need to upload the file to the server. 
- Parse the file using str_getcsv. 
- Run through the array and align as per u need on your website.

You can try with this:
function doParseCSVFile($filesArray)
{
    if ((file_exists($filesArray['frmUpload']['name'])) && (is_readable($filesArray['frmUpload']['name']))) { 
        $strFilePath = $filesArray['frmUpload']['tmp_name']; 
        $strFileHandle = fopen($strFilePath,"r");
        $line_of_text = fgetcsv($strFileHandle,1024,",","'"); 
        $line_of_text = fgetcsv($strFileHandle,1024,",","'"); 
        do { 
            if ($line_of_text[0]) { 
                $strInsertSql = "INSERT INTO tbl_employee(employee_name, employee_code, employee_email, employee_designation, employee_number)VALUES('".addslashes($line_of_text[0])."', '".$line_of_text[1]."', '".addslashes($line_of_text[2])."', '".$line_of_text[3]."', '".$line_of_text[4]."')";
                ExecuteQry($strInsertSql);
            }               
        } while (($line_of_text = fgetcsv($strFileHandle,1024,",","'"))!== FALSE);
    } else {
        return FALSE;
    }
}
