foreach loop

[akshay]

Hello.

 

I need help regarding foreach loop.

 

php.net manual says, foreach means, FOR each element of AN ARRAY, do the following...

 

But, can someone explain me the logic used in these code snipplets (only for foreach statements) :

 

PHP Upload Script:

 

<?php

$file_dir="d:/wamp/www/test/files";

foreach($_FILES as $file_name => $file_array) {  //what does this mean? ONLY the foreach statement
print "Path: ".$file_array['tmp_name']."<br>";
print "Name: ".$file_array['name']."<br>";
print "Type: ".$file_array['type']."<br>";
print "Size: ".$file_array['size']."<br>";
$flnm=$file_array['name'];
if (is_uploaded_file($file_array['tmp_name'])) {
move_uploaded_file($file_array['tmp_name'],
"$file_dir/$flnm") or die("Error!");
print "Upload Successful!";
}
}

?>

 

 

and another one is simpler (printing date values using php getdate() function) :

 

$date_array=getdate();
foreach($date_array as $key=>$val) { //explain this
print "$key = $val<BR>";
}

// I simply use this code:
print "<BR><BR>The Date is:<br>";
print $date_array['mday']." ";
print $date_array['month']." ";
print $date_array['weekday']. " ";
print $date_array['year']." ";
