Question

I have a number of url’s with different query strings such as

 view.php?id=5
 view.php?id=6
 view.php?id=7

on another php page Im using file_get_contents as below:

 $page = file_get_contents('view.php?id=5');
 $file = 'temp/form.html';
 file_put_contents($page, $file);

This of course only writes the first id ‘5’, so how can i retrieve the ‘id’ variable on this page and write it in my file_get_contents line so I dont have to write out all the id’s in seperate lines

thanks

Answer 1

If I understand correctly, in the situation you demonstrate you could use a for loop or something like that. But that only works if the IDs are numeric and follow each other up.

Example:

for($i = 5; $i <=7; $i++) {
  $page = file_get_contents('view.php?id='.$i);
  $file = 'temp/form.html';
  file_put_contents($page, $file);
}

Updated:
If your ID comes from database you could select all IDs and loop through that.
Eg.

$sql = 'SELECT id FROM tablename;';
$res = mysql_query($sql);
while($row = mysql_fetch_assoc($res)) {
  $page = file_get_contents('view.php?id='.$row['id']);
  $file = 'temp/form.html';
  file_put_contents($page, $file);
}
