PHP - Display Ampersand Hex Code From Url In Html

Why do I get the following results (specifically the second example)?  I thought it would be documented under https://www.php.net/manual/en/language.types.string.php, however, the word "ampersand" doesn't appear.  Also, looked at logical operators, but found nothing.  Thanks

function test(string $string){
    printf('%s %s %s 0'.PHP_EOL, gettype($string), $string, $string==0?'==':'!=');
}

test('123');
test('@123');
test('1@23');
test('123@');

Quote

string 123 != 0
string @123 == 0
string 1@23 != 0
string 123@ != 0

 

hello i need help on displaying php code on my website so people can come and just copy it but it wont let me display it

Hey guys,

I'm opening a HTML file from my server, and i can successfully echo it both as code to show the page, and as code which the person can then edit in a <textarea>.

However, there are certain sections of the code i do not what echo'd to the page. What is the best way to go about stipping them? For example i do not want the user to be able to edit the doctype, head element, <header> or <nav> sections of the code.

Thanks in advance
Danny.

hello

I need to fix code display problem. The code below cause the disorder problem. When I delete the part of it , the code display in the right way. I do not really understand it .

 The template try to use  bx_textarea to display code，so I find the function in it. Finally , I found this function cause the disorder code problem.
Code: [Select]
<?php echo bx_highlight(bx_textarea($view_query_result['jdescription']), $kwd_search);?>


Code: [Select]
    if ($char == "<") {
            $skip=1;
        }   
        elseif ($char == ">") {
            $skip=0;
        }   
        elseif ($char == " ") {
            $wrap=0;
         }   
         if ($skip==0) {
            $wrap=$wrap+1;
        }



Code: [Select]
function bx_wordwrap($a_str, $a_break_length=75) {
    $length = strlen($a_str);
    for ($i=0; $i<=$length; $i=$i+1) {
        $char = substr($a_str, $i, 1);
        if ($char == "<") {
            $skip=1;
        }   
        elseif ($char == ">") {
            $skip=0;
        }   
        elseif ($char == " ") {
            $wrap=0;
         }   
         if ($skip==0) {
            $wrap=$wrap+1;
        }
        $res_str = $res_str . $char;
        if ($wrap>$a_break_length) {
            $res_str = $res_str." ";
            $wrap=0;
        }
    }
    return $res_str;
}
function bx_textarea($text) {
  return nl2br(preg_replace('/\t/','&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;',bx_wordwrap($text, 75)));
}//end function bx_textarea($text)

Bad title, I know.
What I mean is I have a code that shows a pop-up error message if you try to post with a username someone else has.
Well, I use this code for my user/pass/message fields:

$user = preg_replace("/[^A-Z a-z0-9]/", "", $_POST['user']);
$password = preg_replace("/[^A-Za-z0-9]/", "", $_POST['password']);
$message = preg_replace("/[^A-Za-z0-9]/", "", $_POST['message']);

What that does is, if you post with, say, a less than or greater than sign, or some other whack character, it makes the field blank for whichever field(s) you enter other characters into.  So really, when someone posts on my forums with a character I do not want them to use in their user/message, it makes the message completely blank, no matter what other allowed characters are used, and the same with the username...so the post will show up without a poster.

My question is, what is a code to use so a pop-up box would show up instead of letting the post go through and post blanks?  Doesn't even have to be a pop-up box, just something to say to the user, "Hey, you can't use (insert disapproved character(s) here)" and to have the post not go through.

I have a form that users input user name, password, and email... all writes to csv fine.  My problem is I need to concatenate a a string with a variable and some html code will preserving the html when written to the csv..

I need the csv to be this

username,password,email,user,category,text with http://sub.domain..com/splash/,something,something

here's what i have

Code: [Select]
<?php
if($_POST['formSubmit'] == "Submit")

$varUserName = $_POST['username'];
$varPW = $_POST['PW'];
$varEmail = $_POST['email'];
{
$fs = fopen("testcsv.csv","a");
fputcsv($fs, array($varUserName,$varPW,$varEmail,"user","title",",category","some text '<a href="http://$varUserName.url.com/splash/>site.com</a>',));
fclose($fs);

exit;
}
?>
and of course I'm getting

Parse error: syntax error, unexpected T_STRING, expecting ')' on line 9

Can I combine also HTML code in PHP function?
For example, can a PHP function include HTML form and the PHP code to handle this form?

If yes, this will make my main code much more smaller and readable.

If not, is there a way to define an "external macro" like, which allow me to replace pre-defined lines of code with short alias?


 

So currently I have 2 files that pretty much does the same thing but connects to 2 different tables. I sort of want to merge it together to save file space and make everything more efficient:

Hi I require a PHP code to get output table.    My Table    Item Qty Date
aa-1 2 2014-10-01
aa-2 5 2014-10-01
aa-3 1 2014-10-01
ab-1 2 2014-10-01
ab-2 1 2014-10-01
bb-1 4 2014-10-01

bb-1 1 2014-10-03
bb-2 8 2014-10-03
bb-3 2 2014-10-03   I wrote code as mentioned below.

<?php

$accounts=mysql_connect("localhost", "root", "") or die("could not connect");  

mysql_select_db("shops",$accounts) or die("could not find db!");

if(isset($_POST['search']) && ($_POST['from']) && ($_POST['to'])){
    $searchq=$_POST['search'];
    $searchq=preg_replace("#[^0-9a-z]#i", "" , $searchq);
    $from=$_POST['from'];
    $to=$_POST['to'];

    $dateInput = explode('-',$from);
    $fdate = $dateInput[2].'-'.$dateInput[1].'-'.$dateInput[0];

    $dateInput = explode('-',$to);
    $tdate = $dateInput[2].'-'.$dateInput[1].'-'.$dateInput[0];
    

    for ($date=$fdate; $date<=$tdate; $date++) {
            $sql = "SELECT  item, SUM(CASE WHEN `date` = '$date' THEN Qty ELSE 0 END)
            FROM shop WHERE item LIKE '%$searchq%' GROUP BY item";  
        $query = mysql_query($sql) or die("could not search!"); 

            echo "<table border='1'>";

                echo "<tr>
                        <td>Item </td>
                        <td>$date</td>
                      </tr>" ;

            while ($row=mysql_fetch_array($query)) {

                echo "<tr>
                        <td>". $row[0] ." </td>
                        <td>" . $row[1] . "</td>
                      </tr>";  
            }               
            echo "</table>";
     }   
} 
?>

I am getting result like this as I asked for three days.

Item	2014-10-01
aa-1	2
aa-2	5
aa-3	1
Item	2014-10-02
aa-1	1
aa-2	2
aa-3	5
Item	2014-10-03
aa-1	1
aa-2	2
aa-3	5

But I need result like below


Item	2014-10-01	2014-10-02	2014-10-03
aa-1	2	        1	        1
aa-2	5	        2	        2
aa-3	1	        5	        5

Can anybody help me to write PHP code to display result as needed. Please help. Thanks in advance.

Hi guys!

How do I display different code depending on the title/url?
This is the code for the form that brings you from
"http://www.xxx.uk/index.php" to "http://www.xxx.uk/index.php?name=ro":
Code: [Select]
<form name="input" action="http://www.xxx.uk/index.php?name=ro" method="post">
 Enter student number:<input type="text" name="sid"/>
<input type="submit" value="Submit">

Now when you are on "http://www.xxx.uk/index.php?name=ro" I would like another content(but written in the same php file).
I tried with _GET, but the problem is that I don't simply want to add a word but a lot of content.
With _GET, that whole content would have to be displayed in the title and I don't want that.

Hey guys

I have a client who wants to upload images then have them display on his page... obviously that process is not an issue at all.
The catch is he wants the image to change at midnight and display the next image in the sequence, then display it until midnight strikes, and then the next in the sequence is displayed.

Is there any code type that will recognise a set time/date and display coressponding images in a database?
I realise I made need to add a field for an ID number/date ID for the code to identify which image to display, but not sure what code will/wont work

Can some one point me in the right direction
would be much appreciated


Thanks
Tom

Hi guys, I am still working on the same code, but encountered another problem. I have a form that takes imput to a MySQL database. It is 5 fields (id,title,category,content,tags). Then I have form a new page that searches with FullText on the (title and tags) fields and echos a link with the content of the result like this:

$link = "<h2><a class='example7' href='tutorial.php?id=" . $rowS['id'] . "&title=" . htmlentities($rowS['title'], ENT_QUOTES) . "&category=" . htmlentities($rowS['category'], ENT_QUOTES) . "&content=" . htmlentities($rowS['content'], ENT_QUOTES) . "&tags=" . htmlentities($rowS['tags'], ENT_QUOTES) . "'>" . htmlentities($rowS['title'], ENT_QUOTES) . "</a></h2><br><br>";

Then when the user clicks this link, it takes them to the tutorial.php page that all it does is echo the content passed by this link and make it look nice.

The problem is that when the data of the content field is greater than 3972 characters in length it doesn't generate the code in the tutorial.php page. It's like if the url is too long to be passed or something... Is that my problem that I'm passing the content in a url? If that is the problem then how can I correct it? How else can I pass the result from the link to the tutorial.php page?

I have a database that contains results of fantasy football games.  I have a query that returns the results of the games team X played against the other teams in the league.  The query works perfect in the database.

Results are
Quote

Opponent Name:    America Enforcers
Wins    Losses    Draws
1                1                0
Last Game:    Week 2 of 2011: 416.6 - 369.8



the query and the php code cycle thru each team that team X has played and brings up team X's record and the results of the last game played.

My problem is that the code stops one team short.  So Team X played teams A, B, C, D, E
but the code only returns teams A, B, C, D
E is left off. 

I can't for the life of me figure out what silly mistake I made.

Any ideas on how to make the magic elvish be good???
Thank you for your time.

Hi,

I'm trying to fetch rows of data from a mysqli table and display them in the browser in categories. I have the while loop working fine, but I want to break the results down into categories, instead of one big list sorted by a field using ORDER BY. So for example, let's say I have a database table containing people's names, email address, phone numbers, etc. and I want to display them in the browser in separate tables by the city in which they live (each city name would be a h1 or h2 tag) and the appropriate rows would be displayed under each heading, sorted by the person's name.

I can do it by using multiple while loops, separating each city into it's own array and then repeating my html table code a bunch of times, but I know there has to be a much cleaner way.

Can anyone point me in the right direction?

Thanks!

I'm trying to submit html/php code through an html form and then insert it into a mysql database. I've got the following code so far (without the insert into database query), however when I submit the form I get pushed through to my 403 page. If i comment out the textarea that contains the code I am trying to submit, then it goes through fine.

Any ideas?
