PHP explode string on if - php

My code that reads an XML file is as follows:
<?php
if ( $dance['block'] == $dance['user']['ip'] ) : ?>
<?php e(o("N/A")) ?>
Right now, that if() statement is reading the entire XML file as one string. So next I used:
$array6 = explode(",", $this->block);
$result['block'] = (string) $array6;
This was supposed to explode each $dance['user']['ip'], but I'm not sure why it's not working.
Any ideas, fixes, or tips?

Casting an array to a string will unhelpfully give you the string "Array" as well as throw a nifty warning. I'm not quite sure what you are trying to accomplish there.
For your test to see if a user's ip is in the block list you should do the following:
$blockList = explode(",", $blockedIpString);
if (in_array($dance['user']['ip'], $blockList)){
// user is blocked
} else {
// user is not blocked
}

php foreach in foreach looping

I want to extrect all usernames and passwords each from his file and output it nicely.
I wrote a code on my appserv 2.5.1 on my computer but only the last loop gave the username output.
Tested the code on other machines and it worked perfectly.
Dont know what is the problem ...
usernames.txt content :
user1
user2
user3
passwords.txt content :
pass1
pass2
pass3
script content :
$usernames = explode("\n", file_get_contents("usernames.txt"));
$passwords = explode("\n", file_get_contents("passwords.txt"));
foreach( $usernames as $username )
{
foreach( $passwords as $password )
{
echo $username.":".$password."\n";
}
}
output :
:pass1
:pass2
:pass3
:pass1
:pass2
:pass3
user3:pass1
user3:pass2
user3:pass3
for ($i=0;$i<count($usernames) && $i<count($password); $i++) {
echo $usernames[$i].':'.$passwords[$i];
}
But $password[x] must be related to $usernames[x]
There's always those that will say you don't need it (and you often don't) but I tend to use regular expressions whenever I'm parsing these kind of flat files - there's always some quirky character, extra line-break or difference that finds it's way into a text file - be it from transferring servers, restoring backups or simply user-interference. You could also make use of array_combine in this situation if you'd prefer to carrying on using a foreach loop - I know some folks prefer it for readability.
preg_match_all('/\w+/m', file_get_contents('usernames.txt'), $usernames);
preg_match_all('/\w+/m', file_get_contents('passwords.txt'), $passwords);
if(count($usernames[0]) !== count($passwords[0]))
die('Computer says: mismatch!'); // some resemblance of error handling...
$result = array_combine($usernames[0], $passwords[0]);
foreach($result as $name => $pass)
echo "{$name}:{$pass}\n";
demo
After debugging with the post author, I guessed that the problem was with the line return character. Using a \r\n fixed the problem:
$usernames = explode("\n\r", file_get_contents("usernames.txt"));
$passwords = explode("\n\r", file_get_contents("passwords.txt"));
For reference, please note that it is very important not to assume your input data is right. If you see that something is wrong and it points obviously to a mistake you made previously (in that case it is clearly not the foreach function that is buggy, but the array), then you need to swallow your pride and debug your own code. I have been programming PHP for 10 years, and I still have to remember that every single day.

preg_match and reg expression using alphanumeric, commas, periods, exclamations, etc

I am having one hell of a time coming up with a decent way make this if statement search a file for these codes. I set up the text file to read from as such:
myfile.txt
r)
0Y7
1a6
q.
#g
#(
#a
!P
T[
V}
0,
Here is a brief of what I got going.
$subject = file_get_contents(fvManager_Path . 'myfile.txt');
if ( preg_match('/^[a-zA-Z0-9,]+$/',$result['fmbushels_itemCode'], $subject) ) {
Basically I am trying to search the text file line by line to see if the whole string exists. They are case sensitive as well.
$result['fmbushels_itemCode'] is from a sql query and always returns a code like the above in the text.
I'd appreciate any help on this. If someone knows a better way of doing this or a different command, I'd be willing to give that a shot as well :)
edit:
private function _fvShareBushels() {
$subject = file_get_contents(fvManager_Path . 'myfile.txt');
if (count($vShareArray) > 0) {
$vCntMoves = count($vShareArray);
for ($vI = 0;$vI < $vRunMainLoop;$vI++) {
sell $result['fmbushels_itemCode']);
}
}
}
This is a snippet of a big code. I had to rip most out because of post limitation. The area I could be working with is:
if (count($vShareArray) > 0) {
If I could make this something like:
if (count($vShareArray) > 0 && $result['fmbushels_itemCode'] **is not in** $subject) {
If you want to do line by line, use the file() function.
$f = file(fvManager_Path . 'myfile.txt');
foreach($f AS $line){
// $line is current line at file
}
I'm not to sure if you understand completely how preg_match works. The first parameter is the regular expression pattern, the second is what you want to match the pattern to, and the third is an array of matches. So for every valid pattern matched in the second parameter a new index on the array is created.
I'm not 100% on what you're trying to accomplish. Are you trying to see if the $result['fmbushels_itemCode'] exists in the file?
If the above is the correct case you simply just need to do something like:
$f = file('myfile.txt');
array_map('trim', $f);
if(in_array($result['fmbushels_itemCode'], $f)){
// success
}

searching for a string while looping

I am trying to format another sites data to insert into my database. He wants to close his site, so is giving me his sites listings. But im having to format his data from his flatfile database, to go into my mysql database.
Im looping through his text file, and getting his values. Then formatting as needed before inserting them into my DB.
Because our sites use completely different storage formats and fields, im having a few problems with something.
My site has a designer field. His doesnt. so im trying to search through his description field to find a match within my designer table. If there is a match i want to get the designer ID to insert into the designer id field. But i cant get this code to work.
Could someone please suggest a fix? or if theres a better way to do this?
$fp = fopen('listings.txt','r');
if (!$fp) {echo 'ERROR: Unable to open file.'; exit;}
$loop = 0;
while (!feof($fp)) {
$loop++;
$line = fgets($fp,1024); //use 2048 if very long lines
$field[$loop] = explode (' ', $line);
$get_designers = mysql_query("SELECT * FROM dress_designers");
$row_designers = mysql_fetch_array($get_designers);
$totalRows_designers = mysql_num_rows($get_designers);
do{
// Note our use of ===. Simply == would not work as expected
// because the position of 'a' was the 0th (first) character.
$mystring = strtolower($field[$loop][8]);
$findme = strtolower($row_designers['designer_name']);
$pos = strpos($mystring, $findme);
// Note our use of ===. Simply == would not work as expected
// because the position of 'a' was the 0th (first) character.
if ($pos === false) {
$designer = "Other";
} else {
$designer = "Siopa Rince";
}
} while ($row_designers = mysql_fetch_assoc($get_designers));
$fp++;
}
fclose($fp);
I only put "Siopa Rince" as a test. But this isnt working. If i take the text from the file, and paste it in the $mystring and put siopa rince in $findme... it works.
Any suggestions would be greatly appreciated!
Thanks,
Danny
OK... what about just entering the info as is? I tried a few different ways, but the result is returning null...
After i insert the data, ill use searches to join the required row to get an ID:
SELECT dress_test.dress_title, (
SELECT dress_designers.designer_id
FROM dress_designers
WHERE MATCH (
dress_test.dress_desc
)
AGAINST (
'dress_designers.designer_name'
IN boolean MODE
)
) AS real_designer_id
FROM dress_test
Another version:
SELECT dress_test.dress_title, dress_designers.designer_name
FROM dress_test
JOIN dress_designers ON MATCH(dress_test.dress_title, dress_test.dress_desc) AGAINST
('dress_designers.designer_name' in boolean mode)
Any other suggestions??
Your first assignment to $row_designers uses mysql_fetch_array, while your second uses mysql_fetch_assoc
Instead of do { ... } while, why not just while () { ... }
Remove this line $row_designers = mysql_fetch_array($get_designers);
And turn your loop into...
while ($row_designers = mysql_fetch_assoc($get_designers)) {
// string search here
}
Everything else looks fine - if you're having troubles, check the values with either echo to print string or print_r to print arrays.

PHP in_array() does not find content that is in an array

i have a very simple script that reads out a txt file, puts the content in an array.
Which does perfectly, i can do print_r($array); and it outputs all the data.
My script:
<?php
$file = 'countries.txt';
$countries_output = file_get_contents($file);
$countries_pieces = explode("\n", $countries_output);
if (in_array("Sweden", $countries_pieces)) {
echo "Sweden was found";
}
else
{
echo'NOT FOUND';
}
print_r($countries_pieces);
?>
I don't understand why it doesn't find the value 'Sweden' in my array, when it clearly is in there.
This is the output: https://pastebin.com/z9rC9Qvk
I also print_r the array, so you can see that 'Sweden' is indeed in the array.
Hope someone can help :)
There is most likely new line characters that you're not taking into account. The following is a cleaner solution using file() and should work for you:
$file = 'countries.txt';
$countries_pieces = file($file, FILE_IGNORE_NEW_LINES);
if (in_array("Sweden", $countries_pieces)) {
echo "Sweden was found";
} else {
echo'NOT FOUND';
}
If there are still some issues, a common normalization is to trim() values to remove some left-overs:
$countries_pieces = array_map('trim', $countries_pieces);
But this must not cure all issues.
Is countries.txt from a Windows machine? If so, splitting on '\n' won't work very well since there's also a '\r' for every line.
Your print_r output would seem to indicate that since there seems to be an extra newline between every line of output.

Phpmyadmin login script

I trying to code a login script for phpmyadmin
<?php
$user = "Domain";
$passwords = file("passwords.txt");
foreach ( $passwords as $pass){
$source = file_get_contents("http://dbadmin.one.com/index.php?lang=en&server=1&pma_username=$user&pma_password=$pass");
if(preg_match("/Database/", $source)):
echo "Login Worked with: {$pass}";
endif;
}
?>
My Problem is it , it dont works here
echo "Login Worked with: {$pass}";
Can you see the problem?
Not necessarily the solution to your problem, but some basic error checking might point you in the right direction. Your problem may even begin at the initial call to file.
$passwords = file("passwords.txt");
if (!$passwords) {
echo 'Unable to read password file';
} //etc
$source = file_get_contents("http://dbadmin.one.com/index.php?lang=en&server=1&pma_username=$user&pma_password=$pass");
if (!$source) {
echo 'Unable to read file source';
} //etc
Also as a side note if you were calling this function on a file outside your filesystem wouldn't you only get the output (HTML) similar to calling it in your browser (not sure if that was your intention).
$source = file_get_contents("http://dbadmin.one.com/index.php?lang=en&server=1pma_username=$user&pma_password=$pass");
if(preg_match("/Database/", $source)):
The value of $source is going to be the full HTML response of getting the url:
http://dbadmin.one.com/index.php?lang=en&server=1&pma_username=$user&pma_password=$pass
preg_match is only going to match on the first line of that string. You will need to parse the string differently or replace any newline characters so it will match on the whole file.
It also looks like you're testing logins to a database using the username "Domain" with a number of different passwords. Not sure if that was your intention, but it seems a bit odd.
