Why is it doing this?

[RARZG]

Hi,

Hope you can all help. this is the code i have wrote for blanking all of my flatfiles.
It works but shouldn`t it just delete all the text in 'website.txt'? but it deletes all of the text out of all of them, also can this script be shrunk in any way?

Thanks alot.

<?
//Declare all flatfiles
$file1 = 'website.txt';
$file2 = 'website2.txt';
$file3 = 'website3.txt';
$file4 = 'website4.txt';
$file5 = 'website5.txt';
$file6 = 'website6.txt';

//Open all flatfiles
$fp1 = fopen( $file1, "w");
$fp2 = fopen( $file2, "w");
$fp3 = fopen( $file3, "w");
$fp4 = fopen( $file4, "w");
$fp5 = fopen( $file5, "w");
$fp6 = fopen( $file6, "w");

//If the files are readable (ie: they exsist)
if (is_readable($file1)) {;

//Input some words into the files. In this case we are inputing "" Which is nothing!
$inputString = ("");

//Open the file and write the input into the file
fwrite( $fp1, $inputString );

//If this doesn`t work, tell me I have done nothing
} else { echo "I have done nothing";

};

What are you trying to do? Why even open all those files if you only want to blank the first one?

I dont get it!

And YES, this code could be shortend dramatically, but first.... whats the point?

I AM trying to clear all the text files. so the code works but i was just asking why? and could it be shortened.

as the code only reads $file1 why does it clear them all?

"if (is_readable($file1)) {;"

fopen with mode "w" truncates file or create it if not exists. Try "r+" mode (reading and writing).

A little shorter version

<?
//Declare all flatfiles
$files = array('website.txt','website2.txt','website3.txt','website4.txt','website5.txt','website6.txt');

// Clear all files
for( $i=0; $i<count($files); $i++ ) {
  $fp = fopen( $files[$i], "w");
  fclose( $fp );
}
?>

I AM trying to clear all the text files.

for ($i = 1; $i == 6; $i++) {
  $f = fopen("website".$i."txt","w");
  fclose($f);
}

wow, thanks jsim & thorpe. that works great. I was trying to get the array working but i kept croping up errors.

If you would be so kind as to look at the second part of my code and possilbly cut it down that would be last problem i promise!!

What the code does is goes to a URL views the source, then via trial and error i adjust each code to copy the html line with the price of the product in it. then the badword filter filters out everything apart from numbers and "." then the program pastes the remaining and hopfully price into the website.txt file for me to view on one page.

Basically i need a program that can grab the price from different URL's that i enter. Viewing the source code and copy & pasting the line then filtering is a working way but I guess my code and thinking is a bit lame.

I guess you guys will be lol when u see the code but a trimmed version will help me price compare quicker.

<?

function filterBadWords($str){
$badwords=array( "[a]", "", "[c]", "[d]" , "[e]", "[f]", "[g]", "[h]" , "", "[j]" ,"[k]", "[l]", "[m]", "[n]", "[o]", "[p]", "[q]", "[r]" , "", "[t]" , "", "[v]", "[w]", "[x]", "[y]", "[z]" , "[<]", "[>]" ,"[/]", "[]" , "[']" , "[%]", "[=]" , "[+]", "[{]", "[}]", "[!]", "[#]", "[&]" , "[*]", "[:]" , "[;]");
$replacements=array( "", "", "" );

for($i=0;$i < sizeof($badwords);$i++){
srand((double)microtime()*1000000);
$rand_key = (rand()%sizeof($replacements));
$str=eregi_replace($badwords[$i], $replacements[$rand_key], $str);
}
return $str;
}
//Start program with the target URL

$lines = file('http://www.ellis-brigham.com/cgi-bin/psProdDet.cgi/204194||@cTents@bThe%20North%20Face|0|user|1,0,0,1|27|');

foreach ($lines as $line_num => $line) {
echo "Line #<b>{$line_num}</b> : " . htmlspecialchars($line) . "<br />\n";
}

$html = implode($lines) ;
//Filter function call
$html = filterBadWords($html);

$file = 'website2.txt';
$fp = fopen( "website2.txt", "w");

if (is_readable($file)) {;
$inputString = ( $html );
fwrite( $fp, $inputString );
echo "<br>";
} else { echo "I have done nothing";
};

$filearray = file('website2.txt');
$fp = fopen( 'website2.txt' ,"w");
$c=count($filearray);
//Added lines to the top - high number mores lines add on to the top
for($i=($c < 155 ? 0 : $c-155);$i < $c;++$i) {
fputs($fp,$filearray[$i]);
}
fclose($fp);

$inp = file('website2.txt');
$out = fopen('website2.txt','w');
//lower the number the more content comes through
for ($i=0;$i<count($inp)-150;$i++)
fwrite($out,$inp[$i]);
fclose($out);

//redirect code here to goto the next url

I guess that was Too much to ask, sorry.
