WHERE ID <=4
(I also added the \ in the replace as I assume you don't need that either)

Meaning of epsilon argument of assertEquals for double values
...nal double DELTA = 1e-15;
@Test
public void testDelta(){
assertEquals(123.456, 123.456, DELTA);
}
If you're using hamcrest assertions, you can just use the standard equalTo() with two doubles (it doesn't use a delta). However if you want a delta, you can just use closeTo() (see javadoc), e.g....

Parse query string into an array
...alone is note accurate, it could display for example:
$url = "somepage?id=123&lang=gr&size=300";
parse_str() would return:
Array (
[somepage?id] => 123
[lang] => gr
[size] => 300
)
It would be better to combine parse_str() with parse_url() like so:

Why would I ever use push_back instead of emplace_back?
... will be invalid after the call.
std::vector<int> v;
v.emplace_back(123);
v.emplace_back(v[0]); // Produces incorrect results in some compilers
On one compiler, v contains the values 123 and 21 instead of the expected 123 and 123. This is due to the fact that the 2nd call to emplace_back re...
