Codes for file upload in PHP (Step 3)

  In this example, we will upload file to the designated location. So, we will create a folder to store the files we've uploaded and give name to that folder. I give it as tnw87. Ok, lets start write the following codes and discover how it works.


<?php

 $name = $_FILES['file']['name'];
 $type = $_FILES['file']['type'];
 $size = $_FILES['file']['size'];

 $tmp_name = $_FILES['file']['tmp_name'];

 if(@isset($name) && @!empty($name)){
 $location = 'tnw87/';

 if(move_uploaded_file($tmp_name, $location.$name)){
  echo $name. ' is successfully uploaded.';
 }else{
  echo 'Upload Errors';
 }

 }else{
  echo 'Please select file to upload';
 }

 ?>

Codes for file upload in PHP (Step 2)

When we upload a file into one location, the file is firstly saved in temporary location as a temp file. Ok, lets discover how it works. We will write the following codes and test it.


 <?php

 $name = $_FILES['file']['name'];
 $type = $_FILES['file']['type'];
 $size = $_FILES['file']['size'];

 $tmp_name = $_FILES['file']['tmp_name'];

 if(@isset($name) && @!empty($name)){
 $location = 'tnw87/';

 if(move_uploaded_file($tmp_name, $location.$name)){
  echo $name. ' is successfully uploaded.';
 }else{
  echo 'Upload Errors';
 }

 }else{
  echo 'Please select file to upload';
 }

 ?>

 <style type = "text/css">
 form{margin-top : 100px; margin-left : 50px;}
 </style>
 <form action = "upload.php" method = "POST" enctype = "multipart/form-data">
 <input type = "file" name = "file"></br></br>
 <input type = "submit" value = "Upload">
 </form>

Codes for File Upload in PHP (Step 1)

This is the first step to write codes for uploading file in php. In this example, you can check name, type and size of files you upload.




 <?php

 @$name = $_FILES['file']['name'];
 @$type = $_FILES['file']['type'];
 @$size = $_FILES['file']['size'];

 if(@isset($name) && @!empty($name)){
  echo 'File name is <strong> '.$name.'</strong>, File type is <strong>'.$type.'</strong> nad File size is <strong> '.$size.'</strong>';
 }else{
  echo 'Please select file to upload';
 }

Using XML with PHP (Example 2)

In this example, you will see using foreach function twice. Ok, let's start write codes. We will write the following xml codes and save it as file name 'example.xml'.

<producer>

      <producer>
             <food>
                   <foodname>banana</foodname>
                   <foodprice>100 kyats</foodprice>
             </food>
       </producer>

       <producer>
             <food>
                   <foodname>lime</foodname>
                   <foodprice>200 kyats</foodprice>
             </food>
        </producer>

       <producer>
             <food>
                   <foodname>milk</foodname>
                   <foodprice>300 kyats</foodprice>
             </food>
       </producer>

</producer>

Using XML with PHP (Example 1)

We will write the following codes and save it as file name 'example.xml'.

         </producer>

WordCensoring in PHP

From the following example, we can learn the usage of form, textarea, isset, strtolower and str_replace. Every word 'love' we type in the text box, the codes will change with the word 'hate'.

<?php

$find = 'love';
$replace = 'hate';

if(isset($_POST['user_input']) && !empty($_POST['user_input'])){ 
   $user_input = strtolower($_POST['user_input']);
   $user_input_new = str_replace($find, $replace, $user_input);
   echo $user_input_new.'</br>';
}else{
  echo 'Please fill in the text box!';
}

?>
