Php trim string from array values -

i have function in class holds several arrays looks this:

protected function gettextitems() {     if($this->haschapters() && !$this->hasimages() && !$this->hasextras())     {         return [[             'title' => 'test1',             'position0' => ['x0' => '165', 'x1' => '400', 'y0' => '265', 'y1' => '400'],             'position1' => ['x0' => '165', 'x1' => '405', 'y0' => '265', 'y1' => '405'],         ],         [             'title' => 'test2',             'position0' => ['x0' => '295', 'x1' => '400', 'y0' => '395', 'y1' => '400'],             'position1' => ['x0' => '295', 'x1' => '405', 'y0' => '395', 'y1' => '405'],         ],         [             'title' => 'test3',             'position0' => ['x0' => '425', 'x1' => '400', 'y0' => '525', 'y1' => '400'],             'position1' => ['x0' => '425', 'x1' => '405', 'y0' => '525', 'y1' => '405'],         ]];     } } 

i tried create string (command) this:

    $itemcounter = 0;     $positioncounter = 0;     $recitemdata = $this->gettextitems();     foreach ($recitemdata $recitemdatakey => $recitemdatavalue)     {         $rec  = 'convert -size 720x480 xc:black -strokewidth 5 ';         $rec .= '-stroke lime ';         $rec .= '-draw "line ' . $recitemdata[$itemcounter]['position'.$positioncounter]['x0'] . ',' . $recitemdata[$itemcounter]['position'.$positioncounter]['y0'];         $rec .= ' ' . $recitemdata[$itemcounter]['position'.$positioncounter]['x0'] . ',' . $recitemdata[$itemcounter]['position'.$positioncounter]['y0'] . '"';         if($itemcounter % count($recitemdata) == 0)         {             $rec .= ' -stroke blue ';         }         $rec .= ' -draw "line ' . $recitemdata[$itemcounter]['position'.$positioncounter]['x1'] . ',' . $recitemdata[$itemcounter]['position'.$positioncounter]['y1'];         $rec .= ' ' . $recitemdata[$itemcounter]['position'.$positioncounter]['x1'] . ',' . $recitemdata[$itemcounter]['position'.$positioncounter]['y1'] . '"';         if($positioncounter <= count($recitemdata))         {             $itemcounter++;         }     } 

currently prints this(which wrong):

"convert -size 720x480 xc:black -strokewidth 5 -stroke lime -draw "line 425,525 425,525" -draw "line 400,400 400,400""

the correct output should this:

convert -size 720x480 xc:black -strokewidth 5 -stroke lime -draw "line 165,400 265,400" -draw "line 295,400 395,400" -draw "line 425,400 525,400" -stroke blue -draw "line 165,405 265,405" -draw "line 295,405 395,405" -draw "line 425,405 525,405"

thanks patrickq found solution. issue was re-initializing value of $rec on each loop.

what simple did declare variable $rec outside of loop.

$rec  = 'convert -size 720x480 xc:black -strokewidth 5 '; foreach ($recitemdata $recitemdatakey => $recitemdatavalue) {     $rec .= '-stroke lime ';     $rec .= '-draw "line ' . $recitemdata[$itemcounter]['position'.$positioncounter]['x0'] . ',' . $recitemdata[$itemcounter]['position'.$positioncounter]['y0'];     $rec .= ' ' . $recitemdata[$itemcounter]['position'.$positioncounter]['x0'] . ',' . $recitemdata[$itemcounter]['position'.$positioncounter]['y0'] . '"';     if($itemcounter % count($recitemdata) == 0)     {         $rec .= ' -stroke blue ';     }     $rec .= ' -draw "line ' . $recitemdata[$itemcounter]['position'.$positioncounter]['x1'] . ',' . $recitemdata[$itemcounter]['position'.$positioncounter]['y1'];     $rec .= ' ' . $recitemdata[$itemcounter]['position'.$positioncounter]['x1'] . ',' . $recitemdata[$itemcounter]['position'.$positioncounter]['y1'] . '"';     if($positioncounter <= count($recitemdata))     {         $itemcounter++;     } }
