POremoving parts of two strings of an array

Body
copied!<p>I'm trying to remove two parts of two strings of an array which is output from ftp_nlist. I am working with CI. ALSO PLEASE NOTE THE MULTI SELECT LIST IN VIEW ARE BEING WORKED ON AND ARE NOT CORRECT CODE WISE. HOWEVER I THOUGHT I SHOULD DISCLOSE THE OTHER SELECT LISTS WHICH SHOWS THE COMPLETE VIEW FILE.</p> <pre><code> { ["parent_directory_one/child_directory_one"]=> int(0) ["parent_directory_one/child_directory_two"]=> int(1) } </code></pre> <p>how to change the above to the following:</p> <pre><code> { ["child_directory_one"]=> int(0) ["child_directory_two"]=> int(1) } </code></pre> <p>then how to change this as follows:</p> <pre><code> { ["parent_directory_one/child_directory_one/child_files_one"]=> int(0) ["parent_directory_two/child_directory_two/child_files_two"]=> int(1) } </code></pre> <p>to the this:</p> <pre><code> { ["child_files_one"]=> int(0) ["child_files_two"]=> int(1) } //controller// </code></pre> <p>ok here's some examples of what I tried and the view files are under construction:</p> <pre><code> //read default remote $glue = '/'; $strs = ''; $root_piece_rm = ltrim($strs, './'); $list_rm = ftp_nlist($conn_id,$root_piece_rm); $list_rm = array_flip($list_rm); $data['list_rm'] = $list_rm; //end read default remote if($rm_targets): $glue = '/'; $list_sub_rm = ftp_nlist($conn_id,$rm_targets); foreach($list_sub_rm as $keys): $list_sub_rm = ltrim($keys,$rm_targets.$glue); $data['list_sub_rm'] = var_dump(array($list_sub_rm)); endforeach; endif; </code></pre> <p>However the following code for the sub directories is the problem and I think ltrim isn't going to work. However the var_dump is outputting the strings trimmed according to the pattern which is $rm_targets.$glue that needs to be removed only showing the sub-directories.</p> <pre><code> //CONTROLLER// $rm_targets = $this->input->post('pt_rm_dirs',TRUE); if($rm_targets): $glue = '/'; $list_sub_rm = ftp_nlist($conn_id,$rm_targets); $list_sub_rm = array_flip($list_sub_rm); $list_sub_rm = array_keys($list_sub_rm); foreach($list_sub_rm as $index): $eraser = ltrim($index,$rm_targets.$glue); endforeach; $data['list_sub_rm'] = $list_sub_rm; endif; </code></pre> <p>Again essentially I need to remove the parent directories from the following strings of an array { ["jm_gallery/new_test_origs"]=> int(0) ["jm_gallery/test_thumbs"]=> int(1) }</p> <p>I'm not sure how the view or controller need to be setup at the moment.</p> <p>The output I get from var_dump below is what I need to show in the multi select list. It is essentially the sub directories but the forward slash and parent removed. I haven't had difficulty with such a scenario until I started working with ftp_nlist and it is extremely disturbing.</p> <pre><code> //CONTROLLER// if($rm_targets): $glue = '/'; $list_sub_rm = ftp_nlist($conn_id,$rm_targets); foreach($list_sub_rm as $keys): $list_sub_rm = ltrim($keys,$rm_targets.$glue); $data['list_sub_rm'] = var_dump(array($list_sub_rm)); endforeach; endif; </code></pre> <p>here's the view file which under construction I want to note again so the loops are not yet correct:</p> <pre><code> //VIEW// <?php if(!defined('BASEPATH'))exit('No direct script access allowed'); ?> <?php echo form_open('test_sftp/test_function')?> <select name="pt_rm_dirs" multiple size="10"> <option value="select one"<?php echo set_select('pt_rm_dirs', 'select_one');?> >select&nbsp;one</option> <?php foreach($list_rm as $folder_rm_dirs => $contents_rm_dirs):?> <option value="<?php echo $folder_rm_dirs?>"<?php echo set_select('pt_rm_dirs', '$folder_rm_dirs');?> ><?php echo $folder_rm_dirs?></option> <?php endforeach;?> <?php unset($contents_rm_dirs);?> </code></pre> <p> Step 2: <p>Specify new names for remote directories selected:</p></p> <pre><code> <select name="ct_rm_subdirs" multiple size="10"> <option value="select one"<?php echo set_select('ct_rm_subdirs', 'select_one');?> >select&nbsp;one</option> <?php foreach($list_sub_rm as $sub_folder_rm):?> <option value="<?php echo $sub_folder_rm?>"<?php echo set_select('ct_rm_subdirs', '$sub_folder_rm');?> ><?php echo $sub_folder_rm?></option> <?php endforeach;?> <?php unset($sub_contents_rm);?> </select> <select name="rm_sub_dirs_files" multiple size="15"> <option value="select one"<?php echo set_select('rm_sub_dirs_files', 'select_one');?> >select&nbsp;one</option> <?php foreach($list_sub_rm as $sub_folder_rm => $sub_contents_rm):?> <optgroup label="<?php echo $sub_folder_rm?>"> <?php foreach($sub_contents_rm as $files):?> <option value="<?php echo $files?>"<?php echo set_select('rm_sub_dirs_files', '$files');?> ><?php echo $files?></option> <?php endforeach;?> <?php endforeach;?> <?php unset($sub_contents_rm);?> <?php unset($files);?> </optgroup> </select> <?php echo form_submit('submit', 'Submit');?> <?php echo form_close()?> </body> </html> <?php echo form_close();?> </code></pre> <p>UPDATE: when I var_dump the code below the strings are changed as I need them but why can't I echo them via the View? I tried converting the strings to an array which became problematic.</p> <pre><code>if($rm_targets): $glue = '/'; $list_sub_rm = ftp_nlist($conn_id,$rm_targets); foreach($list_sub_rm as $keys): $list_sub_rm = ltrim($keys,$rm_targets.$glue); $data['list_sub_rm'] = var_dump($list_sub_rm); endforeach; endif; </code></pre> <p>Any help greatly appreciated!!! Thanks!!!</p>
