scheduling a script to check a directory for files

Greetings!



I need to write a script to import '.csv' data files into MySQL.

My question is how can I have a script execute and check a directory
every 4 hours for any '.csv' files and if it finds any calls a function
to import them?



Thanks,

Dave

On a *nix-box it's fairly simple when using cronjobs... maybe try that?

On linux there is cron (you should find many example by googling) on
windows there is the task scheduler...
And then finally you can use PHPs delay func and a loop ;)

The any part can be done by globbing, DirectoryIterator, shell scripts
...

Linux: man 5 crontab
* */4 * * * /usr/local/bin/php -q import.php

Windows: Scheduled Tasks
[interminible dialogs here]

-------- import.php --------
<?php
//Untested code
//Needs better error handling
//Will not scale well to *large* .csv files...
//Use mysql LOAD DATA IN FILE for large csv files
$path = '/path/to/directory';
$dir = opendir($path) or die("Failed to open '$path'");
while (($file = readdir($dir)) !== false){
if ($file == '.' || $file == '..') continue;
if (!preg_match('|.csv$|i', $file)){
echo "What's '$file' doing in the .csv import directory?\n";
continue;
}
$f = fopen("$path/$file", 'r');
if (!$f){
echo "Failed to open '$path/$file'\n";
continue;
}
while (!feof($f)){
$row = fgetcsv($f, 1000000);
array_map('mysql_real_escape_string', $row);
$row_sql = implode("', '", $row);
$query = "insert into whatever values ('$row_sql')";
mysql_query($query) or die(mysql_error());
}
}
?>
