Many of the times we face a typical question in interviews: “swap two variables without using third variable”. well, when I ask the same question while interviewing any candidate for PHP, I get the same typical answer of adding and subtracting the two variables. But when I ask them to do it with only one executable statement, they simply can’t. …
<?php
$a=10; $b=20;
list($b, $a) = array($a,$b);
?>

# to get matching line and 5 lines before that
grep -B 5 "pattern" file
# to get matching line and 5 lines after that
grep -A 5 "pattern" file
# of course, you can combine -A and -B options together in single command. That's obvious.
# if your -A and -B values are same, you need not specify both the options. use -C instead.
grep -C 5 "pattern" file

My PHP solution to Project Euler problem # 1 http://projecteuler.net/problem=1 If we list all the natural numbers below 10 that are multiples of 3 or 5, we get 3, 5, 6 and 9. The sum of these multiples is 23. Find the sum of all the multiples of 3 or 5 below 1000.
<?php
$sum = 0;
for ($i = 0; $i < 1000; $i++) {
if (!($i % 3) || !($i % 5)) {
$sum += $i;
}
}
echo $sum;
?>

My PHP solution to Project Euler problem # 2 - http://projecteuler.net/problem=2 - Each new term in the Fibonacci sequence is generated by adding the previous two terms. By starting with 1 and 2, the first 10 terms will be: 1, 2, 3, 5, 8, 13, 21, 34, 55, 89, ... By considering the terms in the Fibonacci sequence whose values do not exceed four m…
<?php
$n1 = 1;
$n2 = 1;
$n3 = $n1 + $n2;
$sum = 0;
while($n3 < 4000000) {
$sum += $n3;
$n1 = $n2 + $n3;
$n2 = $n1 + $n3;
$n3 = $n1 + $n2;
