New to PHP...searched the manual, just don't understand how to put it all together. I'm trying to go through a folder and display each html file as it's contents...that part works. I can't figure out how to change a div id incrementally.
This code works for displaying the what I want I just need unique id's in my divs.
$dir = realpath('./path/to/folder/of_files/');
foreach (glob($dir .'/*.html') as $page){
$div = file_get_contents($page);
echo ("<div class=\"interface\" id=\"ID_$id\">$div</div>");
}
Thanks in advance.
If $id
is just some integer you can stick an $id++;
somewhere...
$id = 1;
$dir = realpath('./path/to/folder/of_files/');
foreach (glob($dir .'/*.html') as $page){
$div = file_get_contents($page);
echo ("<div class=\"interface\" id=\"ID_$id\">$div</div>");
$id++;
}
Do it like this:
$dir = realpath('./path/to/folder/of_files/');
$id = 1;
foreach (glob($dir .'/*.html') as $page)
{
$div = file_get_contents($page);
echo ("<div class=\"interface\" id=\"ID_{$id}\">$div</div>");
$id++; //this is just... $id = $id + 1;
}
Or, you can auto increment using foreach's AS syntax.
$dir = realpath('./path/to/folder/of_files/');
foreach (glob($dir .'/*.html') as $id => $page)
{
$div = file_get_contents($page);
echo ("<div class=\"interface\" id=\"ID_{$id}\">$div</div>");
}
Note that you may want to increment $id in the 'echo' statement if you don't want $id to start at 0.
