How do you get PHP to print this...

[lazukars]

I am starting with a string. Let's say that string is "horse.gall up." Now I need to print out every variation of horse without one if its letters plus the ending ".gallup". So the result should be as follows.

orse.gallup
hrse.gallup
hose.gallup
hore.gallup
hors.gallup

Now if someone could figure out how to get the above results with any string that contains a period within it, that would be awesome.

Thanks in advance for any help. I is really appreciated.

Sincerely,
Ryan

See if this suits your needs...
[PHP]<?php

$input = "horse.gall up";

$prefix = strtok($input, ".");
$suffix = strtok(".");

for ($i = strlen($prefix) ; $i>0; $i--)
{
$new_prefix = make_new_combin ations($prefix, $i);

foreach($new_pr efix as $key=>$value)
$new_suffix[$key] = $value.".".$suf fix;

echo "<pre>";
print_r($new_su ffix);

unset($new_suff ix);
}

function make_new_combin ations($word, $length)
{
$word_array = str_split($word );
$new_words = array();

$flags_array = get_combination _flags(count($w ord_array), $length);
foreach ($flags_array as $flags)
{

foreach ($flags as $key=>$flag)
if ($flag == 0)
unset($word_arr ay[$key]);

array_push($new _words, implode("", $word_array));

$word_array = str_split($word );
}
return $new_words;
}


function get_combination _flags($total, $required)
{
$flag_array = array();
$bin = "";

for ($i=0; $i<$total; $i++)
$bin .= "1";
$dec = bindec($bin);

for ($i=0; $i<=$dec; $i++)
{
$num_of_chars = count_chars(dec bin($i), 1);
if ($num_of_chars[49]==$required)
{
$temp = decbin($i);
$length = strlen($temp);
$pre = "";

if ($length<$total )
for ($j=$length; $j<$total; $j++)
$pre .= "0";

$temp = $pre.$temp;
array_push($fla g_array, str_split($temp ));
}
}
return $flag_array;
}
?>[/PHP]

Another code for your weird problem:

<?php
$input = 'horse.gallup';

preg_match("/^([\w]+).([\w]+)$/", $input, $matches);

$prefix = $matches[1];
$suffix = $matches[2];

for ($i = 0 ; $i < strlen($prefix) ; $i++) {
	$a = substr($prefix, 0, $i);
	$b = substr($prefix, $i+1, strlen($prefix));

	$text = "$a$b.$suffix";
	print "$text<br>";
}
?>
