Save image (from javascript) in a public folder (through php)

I am trying to use this package
https://vuejsexamples.com/a-beautiful-vue-component-for-image-cropping-and-uploading/
But then I am wondering how to save my image in a folder.
I am trying to do this in php so that I can use easily the route afterwards, but it could be OK with JS as well if it is easier.
public function uploadfile(Request $request){
$img = $request->img;
$newlocation = $request->newlocation;
$filename = $request->filename;
$img = str_replace('data:image/png;base64,', '', $request->img); //I tried with and without this
return file_put_contents ($newlocation . "/" . $filename , $img );
}
I actually get an image in my public folder but the content is absolutely not what I want :)
The image.jpg contains the text C:\Users\usr\AppData\Local\Temp\phpEE72.tmp

I found this link very helpful when uploading images:
https://hdtuto.com/article/laravel-57-image-upload-with-validation-example
In my controller I have something like this after validation, which allows for different image filetypes like png and jpg:
$name = $request->input('name');
$getimageName = $name.'.'.$request->image->getClientOriginalExtension();
$request->image->move(public_path('filelocation'), $getimageName);
And in my filesystems.php file:
'disks' = > [
'filelocation' => [
'driver' => 'local',
'root' => public_path().'/foldername',
'url' => env('APP_URL').'/public/foldername',
'visibility' => 'public',
]
]

That's the string of the filename. Behind the scenes PHP handles all files uploaded to the server by putting in a temp directory. It's up to you to move it and process it. All you'd need to do is to read the file's contents first:
file_put_contents ($newlocation . "/" . $filename , file_get_contents($img) )
without your str_replace.
You should consider doing this in a more Laravel way as recommended in https://laravel.com/docs/5.8/filesystem#file-uploads but to answer the immediate question, all you need if file_get_contents.

Drupal's .info file doesn't load multiple js files

Although I included multiple .js files in Drupal 7's .info file as advised, only the first ones do load - up to
scripts[] = js/jquery.cycle2.min.js
but not further. Changing the order doesn't help, it seems to stop loading every time at the first cycle-js file.
What am I missing there? Or is it only possible to include max 3 .js for some reason/setting?
core = 7.x
engine = phptemplate
stylesheets[all][] = style.css
stylesheets[all][] = media.css
scripts[] = js/custom.js
scripts[] = js/jquery.cycle2.min.js
scripts[] = js/jquery.cycle2.caption2.min.js
scripts[] = js/jquery.js

You can use following function to add JS on your site:
function mytheme_preprocess_page(&$vars, $hook) {
if (true) {
drupal_add_js(drupal_get_path('theme', 'mytheme') . '/mytheme.js');
drupal_add_js(drupal_get_path('theme', 'mytheme') . '/mytheme1.js');
$vars['scripts'] = drupal_get_js(); // necessary in D7?
}
}

Try another way to include js file .
/your_theme/template.php
function mytheme_preprocess_page(&$vars, $hook) {
drupal_add_js(drupal_get_path('theme', 'mytheme') . 'js/custom.js');
drupal_add_js(drupal_get_path('theme', 'mytheme') . 'js/jquery.cycle2.min.js');
drupal_add_js(drupal_get_path('theme', 'mytheme') . 'js/jquery.cycle2.caption2.min.js');
drupal_add_js(drupal_get_path('theme', 'mytheme') . 'js/jquery.js');
$vars['scripts'] = drupal_get_js();
}
Thank You.

PHP user profile page

Im trying to make a website with users on it, and I'm trying to create a script so that whenever a new user registers it will automatically create a user folder and profile for them but when I try to register it doesn't create the files, could someone please help me with this, Thanks
<?php
include "inc/header.php";
$newfolder = $username;
if (!mkdir($newfolder, 0777, true)) {
die('Failed to create folders...');
}
$pagename = $username;
$newFileName = './u/'.$username.'/'.$pagename.".php";
$newFileContent = '<?php echo "something..."; ?>';
?>

To make a directory/file
if (!file_exists("parent_folder/$username")) {
//Create a file with read write execute PERMISSIONS ENABLED
//Please check : your parent folder also must have 0777 permissions to avoid any kind of read write error
mkdir("parent_folder/$username", 0777);
//now u have to create a FILE with .php
//now this file_put_contents is VERY importnant !
$pagename = $username ;
$newFileName = './parent_folder/$username/'.$pagename.".php";
$newFileContent = '<?php echo "something..."; ?>';
if (file_put_contents($newFileName, $newFileContent) !== false) {
//notify file is created
echo "File created (" . basename($newFileName) . ")";
} else {
//notify u have error
echo "Cannot create file (" . basename($newFileName) . ")";
}
//now create ur .php file in user folder
}
else {
echo "Your parent folder does not exist"
}
Now the possible error and some tips
1) Most of people do fopen("filename_with_PATH", "w")
and expect that file will be generated in PATH folder !
Some times it might fall wrong (depends on version)
fopen is meant to create a file in the directory where your php resides
2) check ur php permission in php.ini if u dont give php permission to write,remote access then u might get some errors (it will be displayed that u have error in my script)
3)For more info and tinkering file_put_contents
Hope this will be helpful for you ..

Recursively generate script tags for all JavaScript files within a directory with PHP

I'm building a complex app with lots of JavaScript files in lots of sub-directories. I know I want to include them all (it won't affect performance), but I don't want to manually create a script tag for each. Given that all of my files are children of a "/js" directory, how could I dynamically generate the script tags for each with PHP? Something like this:
// first somehow recursively get all .js files, then:
foreach($files as $file) {
echo '<script src="' . $file->path . '"></script>';
}

Most elegant way is to use SPL in my opinion.
$dirIterator = new RecursiveDirectoryIterator("/path/to/js");
$iterator = new RecursiveIteratorIterator(
$dirIterator,
RecursiveIteratorIterator::SELF_FIRST
);
foreach ($iterator as $file) {
if($file->getExtension() == 'js') {
// You probably have to adjust the full path according to your DOC_ROOT
$url = $file->getPathname();
echo '<script src="' . $url . '"></script>';
}
}
Have a look at http://php.net/manual/en/class.splfileinfo.php to see what else you can do with $file .

Search for .mp3 files in main folder and subfolders

im looking to make a web player from scratch so I can control my music from my phone. I've got a listing of all files within a folder done, but I need to get it to list the files within the subfolders of the main folder.
So sort of something like \Path\ - Shows all in \Path\ and \Path\subs\ shows the contents of all subfolders.
This is the code that I have written to allow me to search a folder for .mp3 files, but I cannot pin the way to search in subfolders as well.
$.ajax({
url: "music/",
success: function(data){
$(data).find("a:contains(.mp3)").each(function(){
var files = $(this).text().replace(/ /g, '');
files = $(this).text().replace(/.mp3/,'');
$('<p></p>').html(files).appendTo('#displayer');
$('#displayer > p:nth-child(odd)').css('background-color','#DDD');
});
}
});
Many thanks in advance

This is my solution in PHP
<?php
// your mp3 dir
$dir = "dir/";
$result = array();
if(is_dir($dir)){
$iterator = new RecursiveDirectoryIterator($dir);
foreach(new RecursiveIteratorIterator($iterator, RecursiveIteratorIterator::CHILD_FIRST) as $file){
$ext = pathinfo($file, PATHINFO_EXTENSION);
if("mp3"==$ext){
$result[] = $file->getPathName();
}
}
// you can echo json_encode(yourMp3Path) here.
var_dump($result);
}
