[Grabbing all and sending as one]

try this code

$description_message = '';	
	foreach ($hosts as $host)
	{
		$hostdescription = $host["hostdescription"];
		$hostaddress = $host["hostaddress"];
		exec("ping -c $pingcount -w $pingcount $hostaddress", $pingoutput, $Spingstatuscode);
		if ($Spingstatuscode === 0)
		{
			echo("$hostdescription ($hostaddress) is Up <BR>");
			$description_message .= "$hostdescription ($hostaddress) is Up <BR>";
		}
		else
		{
			echo("$hostdescription ($hostaddress) is Down <BR>");
			$description_message .= "$hostdescription ($hostaddress) is Down <BR>";
		}		
	}
	$to = "EMAIL HIDDEN";
	$subject = "SERVER DOWN: $hostdescription";
	$message = "ATTENTION: Please check Server Status below <br>$description_message";
	$headers .= "From: EMAIL HIDDEN\r\n";
	$mail_sent = @mail($to, $subject, $message, $headers);

i have concatenated your messages in $description_message variable and added it in mail body and taken out mail code from foreach loop

i think you database connection is not working, echo the $this->con->connect_errno just below the connection

sorry about that 

 function showData()
 {
        $q = "select * from user where id=" . $this->userId;
        $r = $this->connectionString();
        $result = $r->query($q);
        while ($row = $result->fetch_assoc()) 
        {
            echo $row['name'];
        }
}

try replacing your showdata() function by above function

[access from another class]

where have you defined fetch_assoc() function or is it mysql_fetch_assoc() function

[Editing date]

you need to use $_GET as you are passing variable through query string

 

add below code at the top in edit_form.php page

$number = trim($_GET['number']);

[URL in Profile edit]

<?php
if (isset($_POST['btnsubmit']))
{
$input = "website is ".trim($_POST['website']);
//the above works fine but i want it empty so users can input their own hyperlinked urls
$clickable = preg_replace('*(f|ht)tps?://[A-Za-z0-9\./?=\+&%]+*', '<a href="$0">$input</a>', $input);
echo $clickable;
}
?>
<form action="" method="POST">Update your URL<br />
Email: <input type="text" value="php url" name="email">
Website: <input type="text" value="php url" name="website">
<input type="submit" value="submit" name="btnsubmit">
</form>

use above code

[is_dir() says variable is undefined?]

try by defining $path variable as global in function() or try replacing this line of code

$folders = array_filter(scandir($path), function($item) {
 global $path;
     return is_dir($path . $item); });

[Parse error: syntax error, unexpected '=' in C:\wamp\www\storefront\showitem.php on line 55]

Line 53 - you missed the $ at the start of the item_color variable name

 

 

search this line and apply $

item_color = $colors['item_color'];

[Multicolumn index and searching]

you can optimize your SQL queries by checking that how MySQL executes your queries and that can be done by using EXPLAIN statement

 

refer: http://dev.mysql.com/doc/refman/5.0/en/using-explain.html

 

so when you index your table use EXPLAIN statement to check its possible keys, rows and other details

[session is displaying error after execution]

write your session_start() function at top of your page, there should not be any single space, character etc.(basically any output) before session_start() function

[Strange query results]

actually your query should work as it is, its strange that its not working, you can try assigning "CURRENT_TIMESTAMP" as default value for "lastdl" field and remove it from INSERT query

 

so your query will be 

INSERT INTO weeklydownloads (app_id, week, weekdownloads) VALUES ('{$this->app_id}', '{$this->week}', 1)

may this work for you

[Strange query results]

try changing its data type to timestamp

[Strange query results]

what is data type of field "lastdl"

[finding and replacing keywords in large body's of text]

Use str_replace() function, you can also pass search and replace array

 

http://php.net/manual/en/function.str-replace.php

[GET form errror]

try replacing this line

echo '<td><input type="hidden" name="id" value=' .	$row["id"] . '> </td>';

with

echo '<td><input type="hidden" name="id" value="'.$row["id"].'"></td>';

[change date format]

$date is variable and you are using is as object $date->format('d/m/Y'), so you are getting this error

[Array inside SELECT]

you have passed invalid SQL query to mysqli_query() which return false to mysqli_fetch_array(), so you are getting this error.

 

you cannot pass array in SQL query, you can convert array into comma(,) separated string and can use IN clause in SQL

[Knowledge for a beginner]

check php.net site
