Why doesn t file get contents work

Question

Why does file get contents not work for me   In the test file code below  it seems that everyone s examples that I ve searched for all have this function listed  but it never gets executed   Is this a problem with the web hosting service   Can someone test this code on their server just to see if the geocoding array output actually gets printed out as a string   Of course  I am trying to assign the output to a variable  but there is no output here in this test file       lt html gt   lt head gt           lt title gt Test File lt  title gt   lt script type  text javascript  src  http   maps google com maps api js sensor false  gt    lt  script gt   lt  head gt   lt body gt   lt        adr    Sydney NSW   echo  adr   url    http   maps googleapis com maps api geocode json address  adr amp sensor false   echo   lt p gt    url   lt  p gt    echo file get contents  url   print   lt p gt   file get contents  url    lt  p gt     jsonData     file get contents  url   echo  jsonData    gt   lt  body gt   lt  html gt

If PHP s allow url fopen ini directive is set to true  and if curl doesn t work either  see this answer for an example of how to use it instead of file get contents   then the problem could be that your server has a firewall preventing scripts from getting the contents of arbitrary urls  which could potentially allow malicious code to fetch things    I had this problem  and found that the solution for me was to edit the firewall settings to explicitly allow requests to the domain  or IP address  in question

Check file get contents PHP Manual return value  If the value is FALSE then it could not read the file  If the value is NULL then the function itself is disabled   To learn more what might gone wrong with the file get contents operation you must enable error reporting and the display of errors to actually read them     Enable Error Reporting and Display  error reporting  0   ini set  display errors   1     You can get more details about the why the call is failing by checking the INI values on your server  One value the directly effects the file get contents function is  allow url fopen  You can do this by running the following code  You should note  that if it reports that fopen is not allowed  then you ll have to ask your provider to change this setting on your server in order for any code that require this function to work with URLs    lt html gt       lt head gt                   lt title gt Test File lt  title gt           lt script type  text javascript  src  http   maps google com maps api js sensor false  gt           lt  script gt       lt  head gt       lt body gt   lt  php    Enable Error Reporting and Display  error reporting  0   ini set  display errors   1     adr    Sydney NSW   echo  adr   url    http   maps googleapis com maps api geocode json address  adr amp sensor false   echo   lt p gt    url   lt  p gt      jsonData   file get contents  url    print   lt p gt    var dump  jsonData     lt  p gt       Output information about allow url fopen  if  ini get  allow url fopen      1        echo   lt p style  color   0A0   gt fopen is allowed on this host  lt  p gt      else       echo   lt p style  color   A00   gt fopen is not allowed on this host  lt  p gt          Decide what to do based on return value  if   jsonData     FALSE        echo  Failed to open the URL    htmlspecialchars  url     elseif   jsonData     NULL        echo  Function is disabled      else      echo  jsonData       gt       lt  body gt   lt  html gt    If all of this fails  it might be due to the use of short open tags   lt    The example code in this answer has been therefore changed to make use of  lt  php to work correctly as this is guaranteed to work on in all version of PHP  no matter what configuration options are set  To do so for your own script  just replace  lt   or  lt  php

The error may be that you need to change the permission of folder and file which you are going to access  If like GoDaddy service you can access the file and change the permission or by ssh use the command like  sudo chmod 777 file jpeg  and then you can access if the above mentioned problems are not your case
