PHP function used to read CSV files

The below function can be used to read CSV files and returning an array with all values obtained from the CSV file

USAGE:

Copy the below function to your PHP script

function readCSV($csvFile){
 
 
        $file_handle = fopen($csvFile, 'r');
 
        while (!feof($file_handle) ) {
 
                $line_of_text[] = fgetcsv($file_handle, 1024);
 
        }

PHP: Generate CSV file from a PHP array

Here is a simple but efficient function to generate a .csv file from a PHP array. The function accept 3 parameters: the data, the csv delimeter (default is a comma) and the csv enclosure (default is a double quote).

<?php
function generateCsv($data, $delimiter = ',', $enclosure = '"') { 

$handle = fopen('php://temp', 'r+'); 

foreach ($data as $line) { 

fputcsv($handle, $line, $delimiter, $enclosure);

 } 

rewind($handle); 

while (!feof($handle)) { 

$contents .= fread($handle, 8192); 

}

 fclose($handle); 

return $contents; 

}
?>

feof in PHP

feof — Tests for end-of-file on a file pointer
Syntax:

bool feof ( resource $handle )
Tests for end-of-file on a file pointer.

Parameters:

handle
The file pointer must be valid, and must point to a file successfully opened by fopen() or fsockopen() (and not yet closed by fclose()).

Return values: Returns TRUE if the file pointer is at EOF or an error occurs (including socket timeout); otherwise returns FALSE.



Warning
If a connection opened by fsockopen() wasn't closed by the server, feof() will hang. To workaround this, see below example:
Example #1 Handling timeouts with feof()
<?php
function safe_feof($fp, &$start = NULL) {
 $start = microtime(true);

 return feof($fp);
}

/* Assuming $fp is previously opened by fsockopen() */

$start = NULL;
$timeout = ini_get('default_socket_timeout');

while(!safe_feof($fp, $start) && (microtime(true) - $start) < $timeout)
{
 /* Handle */
}
?>
Warning
If the passed file pointer is not valid you may get an infinite loop, because feof() fails to return TRUE.
Example #2 feof() example with an invalid file pointer
<?php
// if file can not be read or doesn't exist fopen function returns FALSE
$file = @fopen("no_such_file", "r");

// FALSE from fopen will issue warning and result in infinite loop here
while (!feof($file)) {
}

fclose($file);
?>
