Hi @vinpkl. Is there more to your question than this? Could you please clarify it?

In other words, is this just an example of something that is dynamically produced and you want a general php solution for echoing the five version types that you listed? Or was it just as simple as @ahundiak understood, and you just wanted that specific phrase echoed?

Hi WebMachine

i have over 1000 products in the database.

i want break all product names in 5 versions dynamically not manually

if product name is of 6 words then it should break up in 6 versions similar to above format of one to six words

Try this:

    $src  = 'samsung galaxy j5 white 16gb this is a test to see if it works';
    $aSrc = explode(' ', $src);
    $sLine = '';
    foreach($aSrc as $iNotUsed => $src):        
      $sLine .= $src .' '; 
      echo "<br>". $sLine;
    endforeach;

**Output:** >samsung samsung galaxy samsung galaxy j5 samsung galaxy j5 white samsung galaxy j5 white 16gb samsung galaxy j5 white 16gb this samsung galaxy j5 white 16gb this is samsung galaxy j5 white 16gb this is a samsung galaxy j5 white 16gb this is a test samsung galaxy j5 white 16gb this is a test to samsung galaxy j5 white 16gb this is a test to see samsung galaxy j5 white 16gb this is a test to see if samsung galaxy j5 white 16gb this is a test to see if it samsung galaxy j5 white 16gb this is a test to see if it works

John_Betong:

Try this:

$src  = 'samsung galaxy j5 white 16gb this is a test to see if it works';
$aSrc = explode(' ', $src);
$sLine = '';
foreach($aSrc as $iNotUsed =&gt; $src):        
  $sLine .= $src .' '; 
  echo "&lt;br&gt;". $sLine;
endforeach;

Thanks a lot John_Betong

I am not at my computer at the moment and will have a go tomorrow.

Basically within the for next loop append the item to a $newArray = $src

After the array, create another for-next loop from count( $newArray ) down to zero.

Echo the item $src

Have fun and post your script

Hi John_Betong

i tried the below code but everytime it go into infinite loops

<?php
$src  = 'samsung galaxy j5 white 16gb this is a test to see if it works';
    $aSrc = explode(' ', $src);
    $sLine = '';
    foreach($aSrc as $src): 
    $newArray[] = $src;
    $cntArray = count($newArray);
    for($i=$cntArray;$i >0;$i--) {       
      $sLine .= $src .' ';      
      echo "<br>". $sLine;
      }
    endforeach;

?>

and

<?php
$src  = 'samsung galaxy j5 white 16gb this is a test to see if it works';
    $aSrc = explode(' ', $src);
    $sLine = '';
    foreach($aSrc as $src): 
    $newArray[] = $src;
    $cntArray = count($newArray);
    for($i=14;$i >$cntArray;$i--) {       
      $sLine .= $src .' ';      
      echo "<br>". $sLine;
      }
    endforeach;

?>

Try this:

  // IF AND ONLY IF PHP 7
     declare(strict_types=1);
  // OK FOR ALL PHP VERSIONS
     error_reporting(-1); 
     ini_set('display_errors', 'true');

  // SET VARIABLES
     $src   = 'samsung galaxy j5 white 16gb this is a test to see if it works';
     $aSrc  = explode(' ', $src);
     $sLine = '';

  echo '<br>FORWARDS';
      foreach($aSrc as $iNotUsed => $src):        
        $sLine .= $src .' '; 
        echo "<br>". $sLine;
        $newArray[] = $sLine; // ADDED
      endforeach;

  echo '<br><br>BACKWARDS';
        $cntArray = count($newArray) -1;
        for($i=$cntArray; $i >=0; $i--)
        {       
          $sLine = $newArray[$i];      
          echo "<br>". $sLine;
        }

**Output:** [quote]

Hi John_Betong

i would like to ask you a question regarding forloop

what should be done in the code that it should not go into infinite loop mode ??

when it goes into infinite loop mode my computer gets hangs ??

as i a not a expert, so sometimes while writing loops if may get wrong and get into infinite mode and then hangs my computer ??

No simple solution without a example of an infinite loop.

When developing, as shown in post #10, always set maximum error_reporting and display results to the screen.

Also ensure the start, finish and increment are correct. If there is a problem rem out the contents of the for-loop and test. Once OK, remove the rem statements.

If the web-page is taking longer than normal try stopping the page and put in some break-points to debug the problem.

Try using the following debug function:

function  fred($val)
{
  // prettify results
   echo '<pre>' .print_r($val, true) .'</pre>';
}

// example
for( $i=0; $i<42; $i+= 2 )
{
  if ( 20 < $i ) { fred($i); die; }
  echo '<br>' .$i;
}//endfor

echo '<br>should never reach here';

Edit:
My PHP knowledge and expertise is limited and you would be better to create another topic on debugging. Also describe what problems you would like to prevent.

vinpkl · August 6, 2016, 8:09am

why do you think you have limited knowledge.

atleast you have better knowledge than me.

i dont have any particular problem at the moment because you already have solved it.

i was just asking in general.

thanks for the suggestions.
