But I'm even more lazy then Arnold and sure that when there is no variable, then there is no problem. So here are a few tips that can make your code shorter and harder to read :-)
1. Use || (or) and && (and) operations instead of if.
// A lot of code
$status = fwrite($h, 'some text');
if (!$status) {
log('Writing failed');
}
// Less code
${0} = fwrite($h, 'some text');
if (!${0}) log('Writing failed');
// Even less code
fwrite($h, 'some text') or log('Writing failed');
// A lot of code
if ($age < 16) {
$message = 'Welcome!';
} else {
$message = 'You are too old!';
}
// Less code
$message = 'You are too old!';
if ($age < 16) {
$message = 'Welcome!';
}
// Even less code
$message = ($age < 16) ? 'Welcome!' : 'You are too old!';
// A lot of code
$i = 0;
while ($i < 100) {
$source[] = $target[$i];
$i += 2;
}
// less code
for ($i = 0; $i < 100; $source[] = $target[$i+=2]);
$ext = pathinfo('file.png')['extension'];
To handle all these situation you can create a set of small functions which shortcuts frequently used operations
// returns reference to the created object
function &r($v) { return $v; }
// returns array offset
function &a(&$a, $i) { return $a[$i]; }
6. When it is better to write more and then read the code easily, do not be lazy.
Spend a few seconds and write a comment and more readable construction. This is the only tip in this list that really can save hours, not minutes.
