CodeIgniter Resize Image function is not working - php

Question

I have some problem in this code. This code is working on my local windows based system. But the same code in not working on online server. I have a function that convert the big images in to small size images according to the parameters. the code of this function is given below.
public function do_resize($source_file, $target_folder, $height = 128, $width = 128){
$filename = $source_file;
$temp_data = explode('/',$filename);
$new_filename = end($temp_data);
$temp_data = explode('.', $new_filename);
$ext = end($temp_data);
$new_filename = $temp_data[0] . $width .'-'. $height .'.'. $ext;
$source_path = $filename;
$folder_path = '';
$temp_folder = explode('/',$target_folder);
foreach ($temp_folder as $folder) {
$folder_path .=$folder . '/';
if (!file_exists($folder_path)) {
mkdir($folder_path);
}
}
$target_path = $target_folder;
if (file_exists($source_file)) //file_exists of a url returns false.It should be real file path
{
return $folder_path . $new_filename;
}
if(isset($config_manip)){
unset($config_manip);
}
$config_manip = array(
'image_library' => 'gd2',
'source_image' => $source_path,
'maintain_ratio' => FALSE,
'new_image' => $target_path,
'create_thumb' => TRUE,
'thumb_marker' => $width . '-'. $height,
'width' => $width,
'height' => $height
);
$CI =& get_instance();
$CI->load->library('image_lib');
$CI->image_lib->initialize($config_manip);
if (!$CI->image_lib->resize()) {
echo $CI->image_lib->display_errors();
echo "<br>";
echo $config_manip['source_image'];
}
// clear //
$CI->image_lib->clear();
return $folder_path . $new_filename;
}
I am calling this function like this.
$name = $this->imageresize->do_resize($brand['logo'], $target_folder, 50, 50);
Then input parameter $brand['logo'] have this value "uploads/images/system/placeholder.png" and parameter $target_folder have this value "uploads/images/cache/brands/brand-logo".
I did not get any error from this code. but It is not resizing the images also. I also set the permission of the directory to 777.
Any one have some solution for this. Thanks

Change:
if (file_exists($source_file)) //file_exists of a url returns false.It should be real file path
{
return $folder_path . $new_filename;
}
on
if (file_exists($folder_path . $new_filename)) //file_exists of a url returns false.It should be real file path
{
return $folder_path . $new_filename;
}
AND $config_manip:
'new_image' => $target_path,
ON
'new_image' => $folder_path . $new_filename,
:)
