Infinite
Infinite means that an operation is repeated and will never stop being repeated.
Infinite is characteristics of loops, generators, recursive functions and streams. Infinite structures may be a bug or a feature, depending on the usage. For example, the event loop is usually an infinite loop, until one of the event triggers a jump out of the loop.
Infinite is also a PHP constant: INF.
INF is cast to string as 'INF', to integer as 0, to boolean as true, and to float as 'INF'.
<?php
// infinite loops
while(true) { }
for(;;) {}
// infinite generator
function integers() {
$i = 0;
while(true) {
yield $i++;
}
}
// infinite Fibbonacci sequence
function recursive ($a = 1, $b = 1) {
$a2 = $b;
$b2 = $a + $b;
print $b2.PHP_EOL;
recursive($a2, $b2);
}
?>
