In PHP it is possible to write to properties without declaring them. For example, the following is perfectly valid PHP code:
class MyClass { } $x = new MyClass(); $x->foo = true;
Generally, it is a good practice to explictly declare properties to avoid accidental typos and provide IDE auto-completion:
class MyClass { public $foo; } $x = new MyClass(); $x->foo = true;
}
* Dependencies as specified by composer.json
* @return array
public function getRequiredDependencies() {
$deps = [];
if ( isset( $this->contents['require'] ) ) {
foreach ( $this->contents['require'] as $package => $version ) {
if ( $package !== "php" && strpos( $package, 'ext-' ) !== 0 ) {
$deps[$package] = self::normalizeVersion( $version );
return $deps;

// Composer auto-strips the "v" in front of the tag name
