Regarding the entry "Import names cannot conflict with classes defined in the same file".
- I found that since PHP 7.0 this is no longer the case.
In PHP 7.0 you can have a class with a name that matches an imported class (or namespace or both at
the same time).
<?php
namespace ns1 {
class ns1 {
public static function write() {
echo "ns1\\ns1::write()\n";
}
}
}
namespace ns1\ns1 {
class ns1c {
public static function write() {
echo "ns1\\ns1\\ns1c::write()\n";
}
}
}
namespace ns2 {
use ns1\ns1 as ns1; // both a class in ns1, and a namespace ns1\ns1
// the next class causes fatal error in php 5.6, not in 7.0
class ns1 {
public static function write() {
echo "ns2\\ns1::write()\n";
}
}
ns1::write(); // calls imported ns1\ns1::write()
ns1\ns1c::write(); // calls imported ns1\ns1\ns1c::write()
namespace\ns1::write(); // calls ns2\ns1::write()
}
?>
