... a HTML entity. When doing .text(), all HTML entities are decoded to their character values.
Instead of comparing using the entity, compare using the actual raw character:
var x = td.text();
if (x == '\xa0') { // Non-breakable space is char 0xa0 (160 dec)
x = '';
}
Or you can also create the c...

filter_input( \INPUT_SERVER, 'REQUEST_METHOD', \FILTER_SANITIZE_SPECIAL_CHARS )

Why is the use of alloca() not considered good practice?
...of the program's execution.
In the header file:
void DoSomething() {
wchar_t* pStr = alloca(100);

Why does Java's hashCode() in String use 31 as a multiplier?
... for 31 since 33 is not a prime:
Of the remaining
four, I'd probably select P(31), as it's the cheapest to calculate on a RISC
machine (because 31 is the difference of two powers of two). P(33) is

33 is composit...
