Okay, $textAr includes URLs for www.google.com\r and www.yahoo.com.  Do you really want the \r with Google?
Then I see $line: www.google.com being echoed, but don't see the results being echoed.  Replace print_r with var_dump as it likely is returning NULL.
Then I see $line: www.yahoo.com followed by the error message.  I would have expected a line break but not a big deal.
Then I see the $results array with the first element being empty and the second being the error response.
Isn't this what you were expecting?  Consider changing $result[] = $r; to $result[$line] = $r; to make it more clear.

As seen by the first line of my original post, I am using a debugger dbg-php-7.1.so.  Disabled it, and now I see:  Fatal error: Allowed memory size of 134217728 bytes exhausted (tried to allocate 262144 bytes).  Okay, not quite the mystery anymore.

I am sure it can be improved, but for what it is worth, this is what I will be doing.

What a difference a space makes!
$x=new PDO('sqlite:db.sqlite3');

Your missing your trailing semicolon. Ps. You don’t need one in your query.

Instead of having PHP do the trimming, have MySQL do it.  See http://dev.mysql.com/doc/refman/5.7/en/string-functions.html#function_left.
 
Do, why won't DISTINCT or GROUP BY work?.  Are there records like ABCfoo and ABCbar? Maybe the following?
SELECT DISTINCT LEFT(order_discount_code,3) FROM orders ORDER BY order_discount_code ASC;

Not sure I understand your question, so forgive me if you already know this.
 
Every time the browser makes a request to the server, it should include the region name in the URL (maybe use a default region name if none provided, and be sure to use isset() or something to make sure it exists). You then get the data based on the region name, pass it to a template, and display it.
$stmt = $conn->prepare('SELECT x,y,z FROM yourTable WHERE Region_Name=:Region_Name'); $stmt->execute(['Region_Name'=>$_GET['Region_Name']]); $rs=$stmt->fetch(); yourTemplate($rs);

Maybe?
<?php function getIt($var) {     $pos = strpos($var, ' - ');     echo(substr($var, $pos+3)."\n"); } $variable_1 = 'Lulu-free - Swimsuit swimwear red'; $variable_2 = 'Pap & Jones - Bard Mini Dress'; getIt($variable_1); getIt($variable_2);

Ah, I see.
{% set _jsScript = [ 'var types='~types|json_encode()~';' ] %} {% macro listArray(list) %} {% for item in list %} {{ item|raw }} {% endfor %} {% endmacro %} {% if _jsScript|default %} <script type="text/javascript">     {{ forms.listArray(_jsScript) }} </script> {% endif %}

Yea, that was the reason I added "EDIT.  Please disregard (and hopefully delete this post), I am just blind." to the original post.

It is good that you are aware of real_escape_string(), however, no one uses it anymore.  Instead, use a prepared statement ideally PDO.  While there is fancy binding and the like, start off simple.
$username = $_SESSION[info]['username'];         $query = "SELECT $column FROM $table WHERE username =? limit 1"; //Why not hard code your column and table names? $stmt->$yourDataBaseConnection->prepare($query); $stmt->execute([$username]); $rs=$stmt->fetch(); //Or fetchAll() or fetchColumn().  Also, add parameters such as PDO::FETCH_OBJ.

Try the following.  Also, experiment with using $key=>$value in your foreach loops.
<?php $array=[     'catalog'=>[         [             'attributes'=>['book'=>20160122],             'section'=>[                 ['id'=>'F100','title'=>'Across the Sea'],                 ['id'=>'F101','title'=>'Blue Water'],                 ['id'=>'F102','title'=>'Red Rove']             ]         ],         [             'attributes'=>['book'=>20160123],             'section'=>[                 ['id'=>'F103','title'=>'xAcross the Sea'],                 ['id'=>'F104','title'=>'xBlue Water'],                 ['id'=>'F105','title'=>'xRed Rove']             ]         ], ]]; foreach($array['catalog'] as $catalog){     echo('Book: '.$catalog['attributes']['book']."\n");     foreach($catalog['section'] as $section){         echo($section['id'].' '.$section['title']."\n");     }     echo("\n"); } ?>

Solved by using $message = mb_convert_encoding($message, 'HTML-ENTITIES', 'UTF-8');
 
Note that $message= str_replace(' ', ' ', $message); is also no longer needed.

Maybe something like the following...
<?php $data=array(); $query=''; foreach(array('name','phone') as $key) {     if(isset($_POST[$key]) && $_POST[$key]!=''){         $data[$key]=$_POST[$key];         $query.="$key=:$key,";     } } if(!empty($data)){     $sql = 'UPDATE myTable SET '.trim($query, ",").' WHERE id=:id';     $data['id']=123;     $q = $conn->prepare($sql);     $q->execute($data); }
