how can I point PHP glob to a specific directory?
So I got this code to list all jpg images inside a directory but it only works on my root directory and I don't know how to point it to开发者_开发问答 my images directory.
<ul>
<?php foreach (glob("N*T.jpg") as $image): ?>
<li>
<a href="<?php echo str_replace("T", "F", $image); ?>">
<img src="<?php echo "$image"; ?>">
</a>
</li>
<?php endforeach; ?>
</ul>
Can anyone help me with that?
This should work:
glob('images/N*T.jpg');
Otherwise:
chdir('images');
glob('N*T.jpg');
Just prepend the path to the function call.
glob('/path/to/directory/N*T.jpg');
Note that the resulting array will contain the prepended path as well. If you don't want that do
array_map('basename', glob('/path/to/directory/N*T.jpg'));
Just add the path to your function call :
glob("/my/path/to/directory/N*T.jpg")
$files = glob("/path/to/directory/N*T.jpg");
As understand glob
starts with root directory. For example i see image with this
<img src="<?php
echo $_SERVER['REQUEST_SCHEME']. '://'. $_SERVER['SERVER_NAME']. '/public_images/logo_image_.gif';
?>"></img>
Then try
echo pathinfo( glob( 'public_images/logo_image_.*' )[0] , PATHINFO_EXTENSION). ' <br/>';
and see gif
. Location of public_images
is C:\wamp\www\public_images
But for example with
echo pathinfo( glob( $_SERVER['REQUEST_SCHEME']. '://'. $_SERVER['SERVER_NAME']. 'public_images/logo_image_.*' )[0] , PATHINFO_EXTENSION). ' <br/>';
see Notice: Undefined offset: 0 in C:\wamp\www\show_content.php on line ...
However if from file located at C:\wamp\www\some_dir
call file located at C:\wamp\www\public_images
, then need to use echo pathinfo( glob( '../public_images/logo_image_.*' )[0] , PATHINFO_EXTENSION)
