php create objects from list of class files
Question by ing. Michal Hudak
I have directory CLASSES with files in my project.
../classes/class.system.php
../classes/class.database.php
...
I pull out every class and include it to main index.php with this code:
// load classes
foreach (glob("classes/class.*.php") as $filename) {
require_once $filename;
}
and then I create (manually write) objects for example:
$system = new System();
$database = new Database();
...
Q: How can I automatically generate object for each class from list of files in directory CLASSES without writing them?
Thank you for your answers and code.
EDIT:
My working solution:
// load classes
foreach (glob("classes/class.*.php") as $filename) {
require_once $filename;
$t = explode(".",$filename);
$obj = strtolower($t[1]);
$class = ucfirst($t[1]);
${$obj} = new $class();
}

// load classes and create objects
foreach (glob("classes/class.*.php") as $filename) {
require_once $filename;
$t = explode(".",$filename);
$obj = strtolower($t[1]);
$class = ucfirst($t[1]);
// create object for every class
${$obj} = new $class();
}

IF you follow a typical pattern, while creating those files like
class.<classname>.php
Then
foreach (glob("classes/class.*.php") as $filename) {
require_once $filename;
$t = explode(".",$filename);
${strtolower($t[1])}= new ucfirst($t[1])(); // automatically create the object
}
