php get content image folder svg - php

Question

I'm trying to get the svg files from a folder.
Tried the following ways but none of them seems to work:
<?php
$directory = get_bloginfo('template_directory').'/images/myImages/';
$it = new RecursiveIteratorIterator(new RecursiveDirectoryIterator($directory));
while ($it->valid()) { //Check the file exist
if (!$it->isDot()) { //if not parent ".." or current "."
if (strpos($it->key(), '.php') !== false
|| strpos($it->key(), '.css') !== false
|| strpos($it->key(), '.js') !== false
) {
echo $it->key() . '<br>';
}
}
}
?>
And:
global $wp_filesystem;
$path = get_bloginfo('template_directory').'/images/myImages/';
$filelist = $wp_filesystem->dirlist( $path );
echo $filelist;
And:
$path = get_bloginfo('template_directory').'/images/myImages/';
$images = scandir( $path, 'svg', $depth = 0);
echo $images;
And:
$dir = get_bloginfo('template_directory').'/images/myImages/';
$files = scandir($dir);
print_r($files);
And:
$directory = get_bloginfo('template_directory')."/images/myImages/";
$images = glob($directory . "*.svg");
echo '<pre>';
print_r($images);
echo '</pre>';
echo $directory.'abnamro.svg">';
foreach($images as $image)
{
echo $image;
}
I'm kinda lost. I might think that there is something else wrong.
Also checked the privileges for the user but all is okay.
I run Wordpress on a local machine with MAMP.
Any thoughts?

Try the function below, I have notated for clarity. Some highlights are:
You can skip dots on outset in the directory iterator
You can trigger a fatal error if path doesn't exist (which is the issue in this case, you are using a domain-root path instead of the server root path [ABSPATH])
You can choose the extension type to filter files
function getPathsByKind($path,$ext,$err_type = false)
{
# Assign the error type, default is fatal error
if($err_type === false)
$err_type = E_USER_ERROR;
# Check if the path is valid
if(!is_dir($path)) {
# Throw fatal error if folder doesn't exist
trigger_error('Folder does not exist. No file paths can be returned.',$err_type);
# Return false incase user error is just notice...
return false;
}
# Set a storage array
$file = array();
# Get path list of files
$it = new RecursiveIteratorIterator(
new RecursiveDirectoryIterator($path,RecursiveDirectoryIterator::SKIP_DOTS)
);
# Loop and assign paths
foreach($it as $filename => $val) {
if(strtolower(pathinfo($filename,PATHINFO_EXTENSION)) == strtolower($ext)) {
$file[] = $filename;
}
}
# Return the path list
return $file;
}
To use:
# Assign directory path
$directory = str_replace('//','/',ABSPATH.'/'.get_bloginfo('template_directory').'/images/myImages/');
# Get files
$files = getPathsByKind($directory,'svg');
# Check there are files
if(!empty($files)) {
print_r($files);
}
If the path doesn't exist, it will now tell you by way of system error that the path doesn't exist. If it doesn't throw a fatal error and comes up empty, then you actually do have some strange issue going on.
If all goes well, you should get something like:
Array
(
[0] => /data/19/2/133/150/3412/user/12321/htdocs/domain/images/myImages/img1.svg
[1] => /data/19/2/133/150/3412/user/12321/htdocs/domain/images/myImages/img2.svg
[2] => /data/19/2/133/150/3412/user/12321/htdocs/domain/images/myImages/img3.svg
[3] => /data/19/2/133/150/3412/user/12321/htdocs/domain/images/myImages/img4.svg
)
If path invalid, will throw:
Fatal error: Folder does not exist. No file paths can be returned. in /data/19/2/133/150/3412/user/12321/htdocs/domain/index.php on line 123
