for ($i = 1; $i <= 250; $i++){
   echo "$i ";
   echo "$i ";
}

Note you'll have a trailing space after the last 250 with this function.

ok my question was even dumber than the one that asked how to convert a number to its negative counterpart ...

stef 2010-02-02 14:29:22

The `echo`s can be combined so you could have a oneliner:`for ($i = 1; $i <= 250; $i++) echo "$i $i ";`

Code golf time? `foreach (range(1,250) as $i) echo "$i $i ";` shaves 1 char!

Answer 2

+1 A:

for ($i = 1; $i <= 250; $i++) {
    echo $i; // print the first time
    echo $i; // print the second time
}

You can obviously print duplicated value with one echo statement and make the code one line shorter.

Note this function won't print spaces between the numbers.

Answer 4

+3 A:

implode(' ', array_map('floor', range(1, 250.5, 0.5)));

That's a slick way to do it

chris 2010-02-02 15:50:58

This would be fun but implicit way to do it. I'd recommend one of the more obvious solutions.
