is there a way to let's say load up a .txt file with a bunch of lines of text and extract all the words as a list 1 word per line ? and maybe eliminate any words larger then 2-3 characters?

and maybe eliminate any words larger then 2-3 characters? That is going to make it a pretty short list. -
this kind of problem is first year computer science stuff, shouldn't be too hard to find a script example out there

PHP Code:<?php if ( ( $file = file( "file.txt" ) ) !== false ) { foreach( $file as $line ) { $words = explode( " ", trim( $line ) ); foreach( $words as $word ) { if ( strlen( $word ) > 3 ) { echo $word . "\n"; } } } } ?>History will be kind to me for I intend to write it.Comment

/www is the root directory which means it would be localhost/test.phpHistory will be kind to me for I intend to write it.Comment

edit the filename to the one of the txt you already have.
make sure the file is in the same directory as your php script.Comment
-
yah I tried that... i put test.php and test.txt into www folder under C:\wamp\www and when i go to http://localhost/test.php nothing happens just a blank white page in firefox, in explorer says page can't be found... says wampserver is online, it also has index.php in the www folder as well (it came with it) and that page doesn't load either hrmmmm

Is the wampserver icon in the system tray all white? You only need Apache running. Click the icon, goto Apache, Restart ServiceHistory will be kind to me for I intend to write it.Comment

Click wampserver icon, goto Config Files, goto php.ini
Search for "memory_limit" and change the value from 8M to 128M
(You may have to restart the Apache service again)History will be kind to me for I intend to write it.Comment

ok it was already at 128mb, anyways i made file smaller and it worked but all the words are on the same line, not 1 word per line... also they include dots, comas and " ' anyway to get rid of them? here's what it displays now:
morning, stay same room keep watch shifts, never more than three asleep time. Hirschel asked. believe. doesn't have windows. angry Cyr's put-down, Jubal said, windows? What does that matter? killer said. still ruling other possibilities. Besides looking each you, don't want have guard windows. Hirschel said,

If you right click and View Source it will not be on one line. Otherwise, replace "\n" with "<br>" for html output.
Revised code to remove extra chars.
PHP Code:<?php if ( ( $file = file( "file.txt" ) ) !== false ) { foreach( $file as $line ) { $words = explode( " ", trim( $line ) ); foreach( $words as $word ) { $word = ereg_replace( "[^A-Za-z0-9]", "", $word ); if ( strlen( $word ) > 3 ) { echo $word . "\n"; } } } } ?>History will be kind to me for I intend to write it.Comment

everything worked.... thanks for your help man you rock

btw do you have icq/skype? i might need more small scripts (next one i wont be asking for free )
Comment

np.
Just post your problems on GFY, it gives some of us something to do besides look at boobies on an "adult" message board.History will be kind to me for I intend to write it.Comment

One more revision that will give you a listing of unique words (no duplicates).
Enjoy. Now that you have WampServer, head over to PHP.net, read the documentation and learn somethingPHP Code:<?php $unique_words = array( ); if ( ( $file = file( "file.txt" ) ) !== false ) { foreach( $file as $line ) { $words = explode( " ", trim( $line ) ); foreach( $words as $word ) { $word = ereg_replace( "[^A-Za-z0-9]", "", $word ); if ( strlen( $word ) > 3 ) { if ( !in_array( $word, $unique_words ) ) { $unique_words[] = $word; } } } } } foreach( $unique_words as $word ) { echo $word . "\n"; } ?>
History will be kind to me for I intend to write it.Comment
-
btw that latest code you gave gives me this error "Fatal error: Maximum execution time of 30 seconds exceeded in C:\wamp\www\test3.php on line 13" maybe file too big ?Comment
-
yah, i down sized file like 10x smaller, and it worked....
Comment

You know, if you have 6gb of RAM you can use it all. Change the memory_limit to 512MB or 1024MB.History will be kind to me for I intend to write it.Comment
-
Yes, that too. I usually set my localhost to 300 seconds (5 minutes).History will be kind to me for I intend to write it.Comment
-
one more thing, in php.ini should it be
memory_limit = 1024M OR memory_limit = 1024
does it need to have M at the end ? thx
Comment
-
I am not 100% sure but I believe it works on a system like "100K", "100M", "100G", so the "M" would be necessary. Sorry I'm a programmer not a system admin.

hey ProG, anyway you can make me another simple script? to check for any empty lines and lines that start with 0-9 or some weird symbols (such as -,---,===,%---, etc, etc) and remove those lines ? basically to remove any empty lines and lines that start with anything other then a valid character (a-z or A-Z)

if I understand what you are asking for, this will do it nicely:
Code:<?php if ( ( $file = file( "file.txt" ) ) !== false ) { foreach( $file as $line ) { if (ctype_alpha($line{0})) { echo $line . "<br>"; } } } ?>

also note that I used <br> for html output instead of \n so if you need it for your text file use then you should change that part
