PHP - Removal Of Brackets

function send_msg($sender , $message){

        if(!empty($sender) && !empty($message)){

                $sender = mysql_real_escape_string($sender);
                $message= mysql_real_escape_string($message);

                $query = "INSERT INTO  `chat`.`chat` VALUES (null , '{$sender}' , '$message')";    // Difficulty on THIS LINE !!!!

                if($run = mysql_query($query)){
                        return true;
                }else{
                        return false;
                }
        }
           
why is '{$sender}' given the curley brakets ????? and why is message not given the same brackets ? 

also why is this function used ? i.e. mysql_real_escape_string , i know what it does , but is it to prevent SQL injection.

Hi Guys

Quick noob question.

I am still fairly new to oop and i'm trying to also build my first simple mvc to learn about that too.

I came across some syntax use in a tutorial that works but i don't really understand why and don't know what this is called to search for it on google.

I've instantiated the class and then i pull out and explode the url to make controller or function calls in the mvc. The noob bit i don't understand is this

Code: [Select]
$controller->{$url[1]}();
Why do the curly brackets allow you to place a variable name? And what is this type of syntax called so i can read about it.

Any help would be massively appreciated!

hi silly little question but if I want to bracket something inside PHP how do I do it eg my code is

Code: [Select]
  <th class="alignright"><?php echo $ass_descrip; ?>&nbsp;
                           (<?php echo $ass_accro ; ?>) &nbsp;<?php echo FindTypeName ($type_id); ?></th>
printing out         British Eventing  (BE) 

But the brackets at the moment are outside the PHP I want to put a conditional on it and include the brackets inside my conditional statement.?

Code: [Select]
30|24|17,5|4|20,15|13|33,15|22|33,9|20|22
Let's say my output is that,

Realistically every 3numbers is 1 Ticket they are seperated by a "," (comma)

I want to wrap parenthesis around them so the output would look like this

Code: [Select]
(30|24|17) (5|4|20) (15|13|33) (15|22|33) (9|20|22)
Now would I have to use regex.. or not cuz regex is extremely difficult

Thanks 

Hi

Ive been trying to solve this problem for a few hours but am having no luck so would appreciate any help

Im looking for a function/way of extracting info from a dropdown list when a form is submitted. The form field has a name and email address i.e John (john@smith.com) and i just need the email address part to submit into a mysql database.

I tried using the explode() function but this didnt work.

Any ideas?

Cheers
Andy

For example.

I have the following:

Andrew (Age 19)

How would I get the content between the brackets, Age 19 using preg_match_all or a similar function?

Thanks very much

I'm looking for a method to replace everything between brackets.

The patterns that I'm looking for are defined: "/\[([2-9TJQKA][hdcs])\]/"
The pattern inside the bracket could accur 2 or even 3 times inside the brackets.

For example first occurance would be [Ac Kd], here I want to replace Ac into an imge and Kd too.
Later in the text I will most of the time get 3 sets, instead of two: [Jc Td 9d]. The sets always consist of [2-9JQKA][hdcs] and also in this order.
Another example: [2d 2s 2h], or [3s 4h 5c].

If I use the following function, it would not work optimally because some texts do contain some of those sets which should not be converted, ONLY the sets between the brackets:
 

$haystack = setReplace($haystack);

function setReplace($haystack)
{
   $array = array("2s", "2h", "2d", "2c", 
	  	  "3s", "3h", "3d", "3c",
		  "4s", "4h", "4d", "4c",
		  "5s", "5h", "5d", "5c",
		  "6s", "6h", "6d", "6c",
		  "7s", "7h", "7d", "7c",
		  "8s", "8h", "8d", "8c",
		  "9s", "9h", "9d", "9c",
		  "Ts", "Th", "Td", "Tc",
		  "Js", "Jh", "Jd", "Jc",
		  "Qs", "Qh", "Qd", "Qc",
		  "Ks", "Kh", "Kd", "Kc",
		  "As", "Ah", "Ad", "Ac");
		
   for($i=0;$i < count($array);$i++)
   {	
	$result = str_replace($array[$i], "<img src=\"/images/".$code[$i].".png\">",$haystack);
   }
			
return $result;
}

Any ideas?

Hello all!
I cannot seem to figure out a way to pass an object from one page to another.  Now, my flow may be way off, and if it is, please do advise.
I want to have a form for username/password log in.
When the submit button is hit, it takes those values, finds the matching user in the database, and returns the user object.  We'll call him user_object
Now, I want to bring up another page, that allows user_object to enter in additional information (Event details).  After it does this, it writes those Event Objects into the database. 

My problem is: I need the ID Object attached to user_object while inserting the Event Objects into the database.
The user_object and Event Objects values are assigned from two separate forms and two separate submit buttons. 
How do I pass this information?

I don't want to use session because I have a lot of objects and do not want to serialize and unserialize all the time.  I also read that $_GET is a security risk. 

Thanks in advance for any help!

This is the basic logic of the code I am trying:
Code: [Select]
<html form whatevs post>
<php
object_one       
if (creds_match)
{
build_object from db
}
else "Wrong info, dude"
?></endhtml stuffs>
Code: [Select]
<html form whatevs post>
<php
object_two
if (post!empty)
{       
object_two = poststuff
}
assign object_two object_one's _id
insert object_two into db
?></endhtml stuff>
How do I keep the values assigned in section one, and send them or be able to use that same variable in section 2?

Hi Guys I'm trying to remove the brackets around a string with preg_replace
I seem to able to remove the first bracket but not the last. Here are my attempts.....
heres the string


Code: [Select]
$testemail = '(bobbyboo@sample.com.au)';
       echo $testemail;
     
       $testemail2 = trim(preg_replace('/^[\(]/', '', $testemail));
       
            echo $testemail2."<br />";
           
           
            $testemail3 = trim(preg_replace('/$\)/','', $testemail2));
           
            echo $testemail3."<br />";
       
           

is there any way to POST array without brackets in name attribute?

i.e. instead of "product[]" have "product" in the <input name="<NAME>">

Thanks in advance

Is making a double elimination tournament style bracket system capable of being done in php?

After dealing with numerous very well qualified programmers to only turn down the project due to difficulty or lack of a solution I am curious if anyone has figured this out.

I have run across a few sites that have some programs but all turn up to have some issues with the pairing of teams.

Please let me know! If you know the solution, we can work something out as far as payment. This is not a looking for work post, but merely a "can it be done" and if so and you are willing to share the info, it would be greatly helpful.

Hi There,

I'm trying to get the following array to work as a separate include php file to make the HTML easier to follow. Within the HTML it has been working fine, as the "echo $tdata_consent Variable is within the main curly brackets. As soon as I move the variable outside of the brackets I only get 1 item from the array rather than all of the items. 

 $projects_const = array();    
    $required_const = ['Consent'];
    $colors_const =   array_combine($required_const, ['bg-danger text-white font-weight-bold'] );

    $xml_const=simplexml_load_string($jobs_task_response) or die("Error: Cannot create object");
     
    foreach($xml_const->Jobs->Job as $item_const) {
        if (in_array((string)$item_const->State, $required_const)) {     
            $projects_const[] = array(
                'job_no'          => (string)$item_const->ID,
                'job_name'        => (string)$item_const->Name,
                'job_start'       => date('d/m/Y', strtotime($item_const->StartDate)),
                'job_due'         => date('d/m/Y', strtotime($item_const->DueDate)),
                'job_status'      => (string)$item_const->State,
                'job_staff'       => (string)$item_const->Assigned->Staff->Name,
            );
        }
    } 
    
    usort($projects_const, function($a,$b) {return $b['job_due'] <=> $a['job_due']; } );  
 
    foreach ($projects_const as $proj_const) {
        $job_no =$proj_const['job_no'];
        $job_name =$proj_const['job_name'];
        $job_status =$proj_const['job_status'];
        $job_staff =$proj_const['job_staff'];
        $job_due =$proj_const['job_due'];
        $clr_1 = $colors_const[$job_status];
        
        $tdata_const = '';
                        
        $tdata_const .= "<div class='row no-gutters'>";
        $tdata_const .= "<div class='col-sm bg-white border rounded'><a href='managejob.php?job_id=$job_no' class='text-left ml-1'><strong>$job_no</strong></a></div>";
        $tdata_const .= "<div class='col-sm-2 bg-white border rounded'><p class='text-left ml-1'>$job_name</p></div>"; 
        $tdata_const .= "<div class='col-sm-2 bg-white border rounded'>" . state_dropdown_1($job_no, $job_status, $clr_1) . "</div>";
        $tdata_const .= "<div class='col-sm-2 bg-white border rounded'><p class='text-left ml-1'>$job_status</p></div>"; 
        $tdata_const .= "<div class='col-sm-2 bg-white border rounded'><p class='text-left ml-1'>$job_staff</p></div>";    
    
    } 
    echo $tdata_const;

Any thoughts would be much appreciated. Thanks in Advance.

the code is simple but the output is wrong.

Code: [Select]
$str = <<<EOF
a:2:{s:7:"visible";a:7:{i:0;s:5:"email";i:1;s:5:"print";i:2;s:8:"facebook";i:3;s:4:"digg";i:4;s:11:"stumbleupon";i:5;s:7:"twitter";i:6;s:6:"reddit";}s:6:"hidden";a:0:{}}
EOF;
echo "<textarea rows='10' cols='90'>";print_r(unserialize($str));echo "</textarea>";
the ouput is
Code: [Select]
Array
(
    [visible] => Array
        (
            [0] => email
            [1] => print
            [2] => facebook
            [3] => digg
            [4] => stumbleupon
            [5] => twitter
            [6] => reddit
        )

    [hidden] => Array
        (
        )

)
This is wrong I need something like this:
Code: [Select]
array (
  'visible' =>
  array (
    0 => 'email',
    1 => 'print',
    2 => 'facebook',
    3 => 'digg',
    4 => 'stumbleupon',
    5 => 'twitter',
    6 => 'reddit',
  ),
  'hidden' =>
  array (
  ),
)
What am I doing wrong? How do I fix it?

I've noticed some people don't use { } when they right statements, when I first started learning PHP a couple years ago, I thought you HAD to put the curly brackets, but apparently not, how does this work and why don't some people use them in their scripts?

Hi all

I'm quite a competent PHP coder but where it comes to preg_match I prefer to be ignorant, because I can't get my head around the patterns.

Basically, I'm working with a script that someone else has written, and I'm coming across problems because the URL that is being validated sometimes has curly brackets '( )' in it (these are image file names generated by an internal system). I have the pattern, how do I modify this to allow curly brackets? On some occasions, the urls have just the opening or just the closing, so its never the complete set.

if someone could give me an indication with this, because I'm clueless! Thanks in advance!

Ste

pattern:
Code: [Select]
$pattern = '/^(([\w]+:)?\/\/)?(([\d\w]|%[a-fA-f\d]{2,2})+(:([\d\w]|%[a-fA-f\d]{2,2})+)?@)?([\d\w][-\d\w]{0,253}[\d\w]\.)+[\w]{2,4}(:[\d]+)?(\/([-+_~.\d\w]|%[a-fA-f\d]{2,2})*)*(\?(&amp;?([-+_~.\d\w]|%[a-fA-f\d]{2,2})=?)*)?(#([-+_~.\d\w]|%[a-fA-f\d]{2,2})*)?$/';
