Simple dynamic breadcrumb

Question

I think this script is of big interest to any noob around here    including me     What I want to create is a little code that I can use in any file and will generate a breadcrumb like this   If the file is called  website com templates index php  the breadcrumb should show   Website com  gt  Templates    nbsp    link nbsp  nbsp  nbsp  nbsp  nbsp  nbsp  nbsp  nbsp  nbsp  nbsp  nbsp  nbsp  nbsp  nbsp  nbsp  nbsp  nbsp  nbsp  nbsp  nbsp   plain text  If the file is called  website com templates template some name php  the breadcrumb should show   Website com  gt  Templates  gt  Template Some Name    nbsp    link nbsp  nbsp  nbsp  nbsp  nbsp  nbsp  nbsp  nbsp  nbsp  nbsp  nbsp  nbsp  nbsp  nbsp  nbsp  nbsp  nbsp  nbsp  nbsp   link nbsp  nbsp  nbsp  nbsp  nbsp  nbsp  nbsp  nbsp  nbsp  nbsp  nbsp  nbsp  nbsp  nbsp  nbsp  nbsp   plain text

A better one using explode   function is as follows     Don t forget to replace your URL variable in the hyperlink href    lt  php      if  url                  b                links   explode     rtrim  url                foreach  links as  l                b     l              if  url     b                   echo  l               else                  echo   lt a href  URL url    b    gt    l    lt  a gt                               b                             gt

This may be overkill for a simple breadcrumb  but it s worth a shot  I remember having this issue a long time ago when I first started  but I never really solved it  That is  until I just decided to write this up now      I have documented as best I can inline  at the bottom are 3 possible use cases  Enjoy   feel free to ask any questions you may have    lt  php     This function will take   SERVER  REQUEST URI   and build a breadcrumb based on the user s current path function breadcrumbs  separator      amp raquo      home    Home            This gets the REQUEST URI   path to file php   splits the string  using      into an array  and then filters out any empty values      path   array filter explode      parse url   SERVER  REQUEST URI    PHP URL PATH             This will build our  base URL      Also accounts for HTTPS         base      SERVER  HTTPS      https     http               SERVER  HTTP HOST                  Initialize a temporary array with our breadcrumbs   starting with our home page  which I m assuming will be the base URL       breadcrumbs   Array   lt a href    base   gt  home lt  a gt             Find out the index for the last value in our path array      last   end array keys  path            Build the rest of the breadcrumbs     foreach   path AS  x   gt   crumb               Our  title  is the text that will be displayed  strip out  php and turn     into a space           title   ucwords str replace Array   php         Array            crumb                If we are not on the last index  then display an  lt a gt  tag         if   x     last               breadcrumbs       lt a href    base crumb   gt  title lt  a gt               Otherwise  just display the title  minus          else              breadcrumbs      title                Build our temporary array  pieces of bread  into one big string        return implode  separator   breadcrumbs        gt    lt p gt  lt    breadcrumbs     gt  lt  p gt   lt p gt  lt    breadcrumbs    gt       gt  lt  p gt   lt p gt  lt    breadcrumbs          Index     gt  lt  p gt

I started with the code from Dominic Barnes  incorporated the feedback from cWoDeR and I still had problems with the breadcrumbs at the third level when I used a sub-directory   So I rewrote it and have included the code below   Note that I have set up my web site structure such that pages to be subordinate to  linked from  a page at the root level are set up as follows    Create a folder with the EXACT same name as the file  including capitalization   minus the suffix  as a folder at the root level place all subordinate files pages into this folder    eg  if want sobordinate pages for Customers php    create a folder called Customers at the same level as Customers php add an index php file into the Customers folder which redirects to the calling page for the folder  see below for code    This structure will work for multiple levels of subfolders   Just make sure you follow the file structure described above AND insert an index php file with the code shown in each subfolder   The code in the index php page in each subfolder looks like    lt  DOCTYPE HTML PUBLIC  -

Hmm  from the examples you gave it seems like    SERVER  REQUEST URI    and the explode   function could help you  You could use explode to break up the URL following the domain name into an array  separating it at each forward-slash   As a very basic example  something like this could be implemented    crumbs   explode       SERVER  REQUEST URI     foreach  crumbs as  crumb       echo ucfirst str replace array   php       array          crumb

hey dominic your answer was nice but if your have a site like http   localhost project index php the  project  link gets repeated since it s part of  base and also appears in the  path array  So I tweaked and removed the first item in the  path array      Trying to remove the first item in the array path so it doesn t repeat array shift  path     I dont know if that is the most elegant way  but it now works for me   I add that code before this one on line 13 or something     Find out the index for the last value in our path array  last   end array keys  path
