PHP - Recognizing Specific Words In Text

Hello All,

Please excuse my lack of knowledge in advance, I'm a beginner but pick things up relatively quickly, and tend to do things by trial and error.

I would appreciate any help that anyone could offer with the following:

I would like to retrieve two pieces of data from a "text file" and use them to calculate a result from a function I have in javascript. An example of the javascript code is:

<script type="text/javascript">
function calculate() {
var drybulb = document.calc_form.drybulb.value;
var relhum = document.calc_form.relhum.value;
var answer = '';
if (drybulb !== '' && relhum !== '') {
answer = (0.567*drybulb*1) + (0.393 * (relhum*1/100 * 6.105 * Math.exp(17.27 * drybulb / (237.7 + drybulb*1)))) + 3.94;
}
document.calc_form.answer.value = answer;
return false;
}
</script>

Currently this is evaluated with entry from a simple html form, but I would like to have this performed "automatically".


The "text file" that I would like to access is here, not on my server:

http://www.bom.gov.au/fwo/IDV60901/IDV60901.94870.axf

I would like to extract the "air_temp" and "rel_hum" values under the [data] section for use in my function. I just need the "most recent" values (i.e. first), not all those contained in the file. This is a single record from that section (sorry for the mess this no doubt makes):

[data]
sort_order,wmo,name[80],history_product[80],local_date_time[80],local_date_time_full[80],aifstime_utc[80],air_temp,apparent_t,cloud[80],cloud_base_m,cloud_oktas,cloud_type[80],cloud_type_id,delta_t,dewpt,gust_kmh,gust_kt,lat,lon,press,press_msl,press_qnh,press_tend[80],rain_trace[80],rel_hum,sea_state[80],swell_dir_worded[80],swell_height,swell_period,vis_km[80],weather[80],wind_dir[80],wind_spd_kmh,wind_spd_kt
0,94870,"Moorabbin Airport","IDV60901","27/10:00pm","20120227220000","20120227110000",18.8,19.3,"Partly cloudy",510,3,"-",-9999,0.8,17.5,13,7,-38.0,145.1,1013.5,-9999.0,1013.5,"-","11.4",92,"-","-",-9999.0,-9999,"10","-","S",11,6



Would it be possible to obtain these values using PHP?, and if so any advice on how this could be done (noting my minimal knowledge) would be greatly appreciated.

Cheers.

The title says it all,..well as all u can see, there are many methods to accomplish this done but not before undergoing through a heavy tasking process. For instance,
1. Open the file
2. Reads the content of the file into array.
3. Find out the desire line of text that we want to replace.
4. Make that line of text as variable and assigns with the new data(that we want to replace) as its values.
5.open another file.
6.Write the whole contents to the file opened in 5.
7. Put the contents back to the file of original.

Can anyone contributes a better way to get this done? Like replace/delete a specific line without affecting other characters or anything therein?
Thanx.

P.S
reading and using str_replace to make the alteration always ends up in giving some kind of result beyond desired after the first round of code execution.

Hi, My results were fine when displaying them on the browser but then  want to output student's grades depending on what mark they have got. I have put an if statement for this:

    Code: [Select]
   if ($markGrade >= 70){
   $grade = "A";}
But when I put the above if statement in the code then the browser outputs this:

Your Search:

Student Username: 'u0867587'

Notice: Undefined variable: sessionData in /web/stud/u0867587/Mobile_app/student_overall_grade.php on line 79

Notice: Undefined variable: moduleID in /web/stud/u0867587/Mobile_app/student_overall_grade.php on line 91

Notice: Undefined variable: sessionsHTML in /web/stud/u0867587/Mobile_app/student_overall_grade.php on line 93


Why is it not recognisiong any variables?

The code is below and in the attached file.

Can someone help me understand what this type of php is... classes etc..

<?php

// item 1 ***** get the excerpt *****
$excerpt = IDX_Plus::get_data('excerpt');
echo "echo-1  excerpt = $excerpt<br><br>";

// item 2 ***** set the excerpt ***********
IDX_Plus::set_data( 'excerpt', $excerpt);

// item 3 ***** get the excerpt again *******
$excerpt = IDX_Plus::get_data('excerpt');
echo "echo-2  excerpt = $excerpt<br><br>";

// &&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&

// item 4 now shorten the excerpt
// ***** shorten the excerpt ***********
$short_excerpt = wp_trim_words($excerpt,10);
echo "echo-3  short_excerpt = $short_excerpt<br><br>";

// item 5 ***** set short_excerpt ***********
IDX_Plus::set_data( 'short_excerpt', $short_excerpt);


// item 6 ***** get short_excerpt again *******
$short_excerpt = IDX_Plus::get_data('short_excerpt');
echo "echo-4  short_excerpt = $short_excerpt<br><br>";

?>

I can't get it to work so if someone can point me to where I can find info on how this type of php works I will be forever grateful...it pulls data form a cache storage on the web and tries to shorten the output and write the short line back to a new variable..The results look like below:
 

Resulting output:
*****************
echo-1 excerpt = Wonderful family home in desirable South Torrance neighborhood. Light and bright, this 'one owner' home boasts original hardwood floors and 'classic' 1953 tile in kitchen and bath. The freshly painted interior, new kitchen and bathroom faucets, new vinyl floor in bath, and new water heater, make this home move-in ready. Large 'pool size' fenced yard for the kids. Perfect for your buyers who love the classic look of the 50's, or for those looking to remodel and expand.

echo-2 excerpt = Wonderful family home in desirable South Torrance neighborhood. Light and bright, this 'one owner' home boasts original hardwood floors and 'classic' 1953 tile in kitchen and bath.

echo-3 short_excerpt = Wonderful family home in desirable South Torrance neighborhood. Light and…

echo-4 short_excerpt =  the short line does not appear so it must not have saved...

I use the Wholesale Suite Premium Prices plugin with WooCommerce. I have 6 specific wholesale roles out of 15 that I wish to hide two specific shipping methods from being selected for the 6 exceptions. I'm just trying this on my staging server at this time using a code snippet example that I found and modified for my specific conditions. Would the following work for this purpose?

/* Hide specific shipping methods for specific wholesale roles */
add_filter( 'woocommerce_package_rates', function( $shipping_rates ) {
// User role and shipping method ID to hide for the user role
    $role_shipping_method_arr = array(
    'ws_silvia_silver' => array( 'Silvia Premium Standard Shipping (Tracking Service)'),
    'ws_silvia_silver_pst_exempt' => array( 'Silvia Premium Standard Shipping (Tracking Service)'),
    'ws_silvia_silver_tax_exempt' => array( 'Silvia Premium Standard Shipping (Tracking Service)'),
    'ws_silvia_silver' => array( 'Silvia Union Standard Shipping (Tracking Service)'),
    'ws_silvia_silver_pst_exempt' => array( 'Silvia Union Standard Shipping (Tracking Service)'),
    'ws_silvia_silver_tax_exempt' => array( 'Silvia Union Standard Shipping (Tracking Service)'),
    'ws_silvia_gold' =>    array( 'Silvia Premium Standard Shipping (Tracking Service)'),
    'ws_silvia_gold_pst_exempt' => array( 'Silvia Premium Standard Shipping (Tracking Service)'),
    'ws_silvia_gold_tax_exempt' => array( 'Silvia Premium Standard Shipping (Tracking Service)'),
    'ws_silvia_gold' =>    array( 'Silvia Union Standard Shipping (Tracking Service)'),
    'ws_silvia_gold_pst_exempt' => array( 'Silvia Union Standard Shipping (Tracking Service)'),
    'ws_silvia_gold_tax_exempt' => array( 'Silvia Union Standard Shipping (Tracking Service)'),
    );

    // Getting the current user role
    $curr_user = wp_get_current_user(); 
    $curr_user_data = get_userdata($current_user->ID); 

    // Wholesale Suite Roles 
    if (isset($current_user) && class_exists('WWP_Wholesale_Roles')) {
        $wwp_wholesale_roles = WWP_Wholesale_Roles::getInstance();
        $wwp_wholesale_role = $wwp_wholesale_roles->getUserWholesaleRole(); 

// Loop through the user role and shipping method pair
    foreach( $role_shipping_method_arr as $role => $shipping_methods_to_hide ) {

// Check if defined role exist in current user role or not
    if( in_array( $role, $current_user->roles) ) {

// Loop through all the shipping rates
    foreach( $shipping_rates as $shipping_method_key => $shipping_method ) {
$shipping_id = $shipping_method->get_id();

// Unset the shipping method if found
    if( in_array( $shipping_id, $shipping_methods_to_hide) ) {
unset($shipping_rates[$shipping_method_key]);
}
}
}
}
}
    return $shipping_rates;
});

Any insights as to how to accomplish this would be greatly appreciated. Lyse

I have a strange problem. When a guest visits my contact-user.php page, they get a message telling them the must login before viewing the page.

After the guest logs in, they view the same page and it tells them they have to login again (keeps on looping). But if they manually refresh that page with the "you must be logged in" message, it recognizes the login and lets them in.

How can I get this page to immediately recognize that the user is logged in and not require them to refresh the page manually?

Here is my code for contact-user.php

<?php 
session_start();
header("Cache-Control: private, max-age=10800, pre-check=10800");
header("Pragma: private");
header("Expires: " . date(DATE_RFC822,strtotime("+2 day")));
include("connection.php"); 
mysql_select_db("database");


if (isset($_SESSION['username'])) { 
********    MY HTML PAGE CONTENT     ********
 }


else {
echo "<meta http-equiv='REFRESH' content='2;url=http://www.mysite.com/login.php'>
<center><font color='#EE0000'><p>You must be logged in before negotiating. You will now be redirect to the login page.</p></font></center>";
}
?>



Here is my code for login.php script:

<?php
include("connection.php"); 
mysql_select_db("database");
session_start();
if(isset($_POST['login'])){
       $username = mysql_real_escape_string($_POST['username']);
       $password = mysql_real_escape_string($_POST['password']);
   $tUnixTime = time();
       $sGMTMySqlString = gmdate("Y-m-d H:i:s", $tUnixTime);
       if (!$username || !$password) {
          print "Please fill out all fields.";
          exit;
       }
       $logres = mysql_num_rows(mysql_query("SELECT * FROM members WHERE username = '$username' and password = '$password'"));
       if ($logres <= 0) {
          print "Login failed. If you have not already, please signup. Otherwise, check your spelling and login again.";
          exit;
       } 
       else {
       $_SESSION['username'] = $username;
       if (isset($_SESSION)) {
         echo'You are now logging in'; mysql_query("UPDATE members SET activity = '$sGMTMySqlString' WHERE username = '$username'");
       }
       else {
         echo "You are not logged in!";
       }  
       echo'<html><head><meta http-equiv="REFRESH" content="1;url=http://www.mysite.com/members/' . $_SESSION['username'] . '/"></head><body></body></html>';
       exit;

Hello dear friends,

I've an idea so let us say we have paragraph with bad words 

Code: [Select]
$para = "Hello shit oh shit what the hell this is shit day";
Now let say we create textarea

Code: [Select]
<textarea id="badword" name="badword">
</textarea>
and let us say we have database table as following

Code: [Select]
CREATE TABLE `banned` (
 `id` varchar(50) NOT NULL default '',
 `badwords` text NOT NULL,
 PRIMARY KEY  (`id`)
) ENGINE=MyISAM DEFAULT CHARSET=utf8;

consider we have connetion and can update mysql table badwords

1- now how we can enter word per line in this textarea

example we entered in this textarea per line
shit
hell
die
death

then by click on submit it stored in an database table 'banned' as

INSERT INTO `banned` VALUES ('1', 'shit,hell,die,death');


2- if we called `badwords` from table 'banned' how then can put 'shit,hell,die,death' into array so we can exclude it from $para

 
can someone please help me in this , how to store textarea per line as sperated words in database table and how then call it back as array to exclude it form our paragraph

Or

it there any other simple way doing the same 

thank you

: : NEW Problem

I want to replace bad words which someone has inputted into my HTML textarea, with something like [CENSORED].
Here's what I've got so far:
note: $review is the posted textarea name.
Code: [Select]

$words_text = 'badwords.txt';
$bad_words = file($words_text);
               
$good_words = str_ireplace($bad_words,'[CENSORED]',$review);
         
echo $good_words;


The thing is, if I type bad words in the textarea, I still get bad words when I echo $good_words.

I don't know why I'm getting this, any ideas

hi,

now i have something like this:

$pizza  = "piece1 piece2 piece3 piece4";
$one_word = explode(" ", $pizza);

but i want to get 2 words together, like that:

$two_words[0]='piece1 piece2';
$two_words[1]='piece3 piece4';
$two_words[2]='piece2 piece3';
$two_words[3]='piece1 piece4';

if it's impossible with explode, then it's fine if you use some other function, i don't care as long as it works.

thank you, tastro

I'm pretty sure the problem is starring me in the face, but I can't seem to locate it.


function filter($string)
{
//swear words pulled from bannedwordlist.com
$f = fopen('../badwords.txt', 'r');
$bad_words = fread($f, filesize('../badwords.txt'));
$bad_words = explode('\n', $bad_words);

$input = strtolower($string);

foreach($bad_words as $value)
{
$string = str_replace($value, '****', $input);
}

return $string;
}


UPDATED CODE

function filter($string)
{
//swear words pulled from bannedwordlist.com
$f = fopen('../badwords.txt', 'r');
$bad_words = fread($f, filesize('../badwords.txt'));
$bad_words = explode('\n', $bad_words);

$input = strtolower($string);
$string = str_replace($bad_words, '****', $input);

return $string;
}


I've already echoed out $value in the foreeach loop, and it does correctly retrieve the bad words and put them into an array. My only problem is, the returned string is still in strtolower() form, and the words aren't censored. :/

Hi, having a really strange problem, i have a form like this:

<form method='post' action='addcart.php'>
echo $name //prints both parts of name separated by space
<input type='hidden' value='$name' name='na'

and then in the addcart.php
echo $_POST['na']   //only prints first half of name

So for example, if $name was "Product One" when i print the value in first script it prints Product One fine but when i print in the other script it only prints "Product".  This then leads onto only half the name being copied into a database. 
I'm sure this was working fine before, not sure what the problem here is...

I'm trying to pull in data using a particular word from a mysql db (it's like a search facility).

But this code only picks if the db has got the exact same word.
E.g. if fincom = "DALLS" it pulls the data only when "searchwords" has DALLS. It ignores if "searchwords" has BARBIE DALLS. How can I fix this. I need to pick all records which contains the search word 'fincom' anywhere in  searchwords.

Hope this makes scene.

$SomeVar = $_POST['fincom'];
$query = "SELECT * FROM  news_home WHERE searchwords = '".$SomeVar."' ORDER BY timestamp DESC";
$results = mysql_query($query);

I would like to get all words from a site in a array.
I found this great thing:
http://simplehtmldom.sourceforge.net/

however it makes use of:
file_get_contents

which gives me:
Warning: file_get_contents() [function.file-get-contents]: http:// wrapper is disabled in the server configuration by allow_url_fopen=0 in

And my hosting doesn't allow a change for that, they tell me to use curl.

With curl i get this:
Warning: curl_setopt() [function.curl-setopt]: CURLOPT_FOLLOWLOCATION cannot be activated when safe_mode is enabled or an open_basedir is set in

It's caused by this line:
 curl_setopt($ch, CURLOPT_FOLLOWLOCATION ,1);

But setting it to 0 cause then instead of getting the word from the page i want i get the following words in a array:
302 Moved The Document has moved here

What can i do now?
