php - File_exists function is not working -

-

since problem on file_exists() , seems function should goes root directory, when determine file location on file_exists function declare base url because tests file location server not url :

wrong code

    $dir = base_url()."assets/produits/";      foreach ($rows $row) {         $nom = $row->nshape;         $type = array(".jpeg", ".jpg");          foreach ($type $ext) {             echo "<br>i'm in foreach loop <br>";             $file_name = $dir . $nom . $ext;              if (file_exists($file_name)) {                echo "i'm in file_exists function<br>";                $img_src = $file_name;             } else {                 echo "i'm in else statement <br>";                 echo $file_name."\n";                 $img_src = $dir . "none.png";             }         }     }

the problem full name there treat doesnot exists, i've made echos check did code reaches , here's screeenshot : screen shot of problem

knowing http://localhost/dedax_new/assets/produits/2052.jpegexists in server.

solution :

// set default no find image $img_src = base_url() . "assets/produits/none.png";  foreach ($rows $row) {     $nom = $row->nshape;     $type = array(".jpeg", ".jpg");      foreach ($type $ext) {         $file_name =  $nom . $ext;          if (file_exists("./assets/produits/".$file_name)) {            $img_src = base_url() . 'assets/produits/'.$file_name;;            // found file exists 'get out of dodge'            break;         }     }

thanks contributors in advance.

file_exists works on file system , not on web. using web address rather file location.

also current loop possible find file first time round loop using first ext , fail find file second ext , assume there no file found.

so try this

$dir = "dedax_new/assets/produits/";  // set default no find image $img_src = $dir . "none.png";  foreach ($rows $row) {     $nom = $row->nshape;     $type = array(".jpeg", ".jpg");      foreach ($type $ext) {         echo "<br>i'm in foreach loop <br>";         $file_name = $dir . $nom . $ext;          if (file_exists($file_name)) {            echo "i'm in file_exists function looking $filename";            $img_src = $file_name;            // found file exists 'get out of dodge'            break;         }     } }

also other common mistake not respect case sensitivity of file system. make sure respect case sensitivity of file's location url not match file system's configuration.
