the file and somehow replace each letter by its number, then add each letter
for each word and see which words would equal to 100.
So I am emailing this list for any suggestions or examples of code that I
can use to accomplish this. Any help?
function total ($word) {
$total = 0;
$word = strtoupper($word);
for ($i=0; $istrlen($word); $i++) {

echo total('acronym');

Re: [PHP] Anagram Solution in PHP
maybe you forgot something like:
.
$letter=26-(ord($word[$i])-65);// excellent !!!
if (($letter1)||($letter26))
$letter=0;
$total+=$letter;

[PHP] Anagram Solution in PHP
Im trying to figue out the following anagram using PHP. Here is the problem: Using letters of the alphabet represented by a number, I have to come up with words that add up to exactly 100. Numbers are in reverse where A=26 and Z=1, so for example: A B C...X Y Z 26 25 24..3 2 1 So let's say the word 'acronym' A + C + R + 0 + N + Y + M 26 + 24 + 9 + 12 + 13 + 2 + 14 = 100 My thoughts were to download a list of words in the dictionary, then read the file and somehow replace each letter by its number, then add each letter for each word and see which words would equal to 100.

RE: [PHP] Anagram Solution in PHP
Sounds like you know exactly what you want to do :-) 1) Obtain a text file, csv or whatever of a dictionary (easy enough - www.google.com). 2) Find the ascii values for a-z or A-Z, your choice. 3) Read in a word at a time. 4) Convert to upper or lower case to reflect part (2) 5) Create a simple formula that converts the ascii codes into the range 1-26. Something like ascii code of z - ascii code of letter + 1 should do the trick. 6) add them all up. simple. - seb -Original Message- From: Ralph Guzman [mailto:[EMAIL PROTECTED]] Sent: 10 September 2001 09:26 To: PHP General Mailing List Subject: [PHP] Anagram Solution in PHP Im trying to figue out the following anagram using PHP.

I tried that code this morning :

q=10,r=9,s=8,t=7,
u=6,v=5,w=4,x=3,
y=2,z=1);
$fid=fopen(testfile.txt,r);
$line_num=0;
while (!feof($fid))
{
$line_num++;
$line = strtolower(fgets($fid,4096));
$words= explode( ,$line);
while (list($foo,$word)=each($words))
{
$word_value=0;
for ($car=0;$carstrlen($word);$car++)
{
if ($letter_value=$tab[$word[$car]])
$word_value+=$letter_value;
}
if ($word_value==100)
echo the word b$word/b on line $line_value of
the input file has a value of $word_value.br\n;
}
}
echo br\nfont color=\red\If nothing appears above, no word with
a value of 100 was found !!!\n;
