How to write file to desktop in laravel? - php

Question

I am trying to write a backup for my database,
I want If a button is clicked the application will export the database to the desktop.
The app exports the file on my database directory if I use laravel database directory path
but if I change the path to desktop location nothing appears on the desktop.
$get_all_table_query = "SHOW TABLES";
$result = DB::select(DB::raw($get_all_table_query));
$tables = [
'users',
'migrations'
];
$structure = '';
$data = '';
foreach ($tables as $table) {
$show_table_query = "SHOW CREATE TABLE " . $table . "";
$show_table_result = DB::select(DB::raw($show_table_query));
foreach ($show_table_result as $show_table_row) {
$show_table_row = (array)$show_table_row;
$structure .= "\n\n" . $show_table_row["Create Table"] . ";\n\n";
}
$select_query = "SELECT * FROM " . $table;
$records = DB::select(DB::raw($select_query));
foreach ($records as $record) {
$record = (array)$record;
$table_column_array = array_keys($record);
foreach ($table_column_array as $key => $name) {
$table_column_array[$key] = '`' . $table_column_array[$key] . '`';
}
$table_value_array = array_values($record);
$data .= "\nINSERT INTO $table (";
$data .= "" . implode(", ", $table_column_array) . ") VALUES \n";
foreach($table_value_array as $key => $record_column)
$table_value_array[$key] = addslashes($record_column);
$data .= "('" . wordwrap(implode("','", $table_value_array),400,"\n",TRUE) . "');\n";
}
}
$file_name = dirname("C:\Users\ADC-2\Desktop") .'/database_backup_on_' . date('y_m_d') . '.sql';
$file_handle = fopen($file_name, 'w + ');
$output = $structure . $data;
fwrite($file_handle, $output);
fclose($file_handle);
echo "DB backup ready";
It will display DB backup ready but nothing really shows up on the desktop.

Answer 1

dirname()
Use
"C:\\Users\\ADC-2\\Desktop"
instead of
"C:\Users\ADC-2\Desktop"
