<div dir="ltr" style="text-align: left;" trbidi="on">
In this Tutorial, We are going to show you how to store file name into the database and upload into a folder. First of all, we have to create database named testing using the PHPmyadmin database panel. 1). After creating database, Now need to create one table named "file_storage_table". CREATE TABLE IF NOT EXISTS `file_storage_table` (   `id` int(11) NOT NULL AUTO_INCREMENT,   `filename` varchar(250) NOT NULL,   PRIMARY KEY (`id`) ) ENGINE=InnoDB DEFAULT CHARSET=latin1 AUTO_INCREMENT=1 ; 2). After creating the table, create one folder called "file_upload" and keep files into www folder or htdocs folder. www or htdocs – file_upload 3). Create folder with named 'store' into the file_upload folder- and set permission like 777 for store folder (Given Permission - Read, Write, Execution) www or htdocs – file_upload – store 4). Now here is the time to create PHP files into the file_upload folder for execution. www or htdocs – file_upload – store - index.php - database_conn.php – upload.php In the Index.php file Write the below code exactly it is written. 
<pre class="brush:html;">

How to Increase memory limit and max execution time in php.ini file?

<div dir="ltr" style="text-align: left;" trbidi="on">
In this Tutorial, We are going to show you how to increase memory limit or max_execution_time. some time we get an error in SQL database while uploading large database or uploading an image with large size throgh file input. In this way database return an error with "Allowed memory size of 103809024 bytes exhausted (tried to allocate 0 bytes)". 
 
for this solution, PHP has some default limitation in its configuration file. for example: - We can upload an image with 2MB or less then to it. 
so some times php script stop its execution and shows this error. 
 
So after increasing some value in php.ini file we can correct it like: - 
 
memory_limit = 1000M 
max_execution_time = 1000     // by default 300 
upload_max_filesize = 10M     // by default 2MB 
post_max_size = 240M 
 
memory_limit : Memory limit is required for buffering. If memory limit enabled by the configuration script, then memory_limit also affects on image or file uploading. So, memory limit should be greater than (post_max_size). 
 
upload_max_filesize : The default upload file size is always 2MB. but we can increase it according to the purpose. 
 
post_max_size : (post_max_size) This setting also affects file upload with PHP script. To upload large size file, This value must be greater than upload_max_filesize. 
 
max_execution_time : Obvious, if the file size is large then it will take long time for uploading or execution of php script. so we need to increase it according to execution time. 
 
 
Some time it do not work and again you will get an error like this. because yo need to correct it at another file and change the max_exection time into it. 
 
Follow the path - >       C:\wamp\apps\phpmyadmin3.5.1\libraries 
and select file and open it.      (config.default.php) 
 
Then Search for the keyword with   = $cfg['ExecTimeLimit'] = 300; 
Default value for execution is 300. so you need to increase it according to the running PHP script. 
 
like: - $cfg['ExecTimeLimit'] = 300000; 
 
If you still facing any difficulty then feel free to contact me with the help of contact us or if you have any suggestion about any article then you can also write to us. 
 
Happy Coding.

Oops (Object oriented programming) Basic Interview Questions

<div dir="ltr" style="text-align: left;" trbidi="on">
In this Post, I am going to show you some generally asked questions during the interview. 
 
1.) What is Object Oriented Programming? 
Object oriented programming-{OOP} is a programming language in which all the programming code organize around or with objects rather than other execution. 
Objects are known as an instances of a class and used to interact with one another objects. 
 
There are various languages in which object oriented language is used like: - 
JavaScript(Object Oriented), PHP(Object Oriented), Objective-C, C++, .Net, Python, Ruby and etc. 
 
The Main Purpose of using object oriented programming are: 
 
1). Robust programming. 
2). Easy understanding. 
3). Reuse Functioning or Coding. 
4). Easily to maintenance. 
5). Easy evolution. 
 
 
2.) What is data Modeling in OOPs? 
In the class code, We create multiple get/set functions for getting and setting data with the protected function is known as Data Modeling in Object oriented. 
<pre class="brush:php;">

class dataModel {
 public function __set( $key, $value ) 
  {
      $this->$key = $value;
   }
 }

</pre> 
3.) What is difference between class and interface? 
 
1). Interface Don't have business logic in code. 
2). for Using Interface we need to extend interface to use. 
3). Code doesn't allow to create object of interface. 
 
4). What do you know about PHP parse error? 
We face the parse error when ever code gets syntax error into it. 
With Example: - Each and every line should have semicolon in PHP. if we do not use the semicolon into it then, it shows the parse error and code get stop its execution. similarly, if we forget to use double quotes in string then we get parse error in code. 
With this we get the exact line in PHP code where we get the error. So we can find the error and can correct it instantly. 
 
In the Below written code, We will get the parse error into it. Because We didn't use the semicolon in line. 
<pre class="brush:php;">

</pre>
5). Objects can be passed by value or by reference? 
 
In the Object oriented programming, Everything is passed by value. 
 
If you feel any difficulty into the question then feel free to contact us. Don't forget to give feedback.

What is Ajax? How to use it into Project with Basic Examples?

<div dir="ltr" style="text-align: left;" trbidi="on">
In this tutorial, We are going to describe you about Ajax and JQuery Details. like what is Ajax and how to use it into our projects. 
 
Full form of Ajax :- Asynchronous JavaScript and XML 
Ajax is used for loading data into the background and append on the webpage without reloading the web page. 
Now a days, Every Web-Application is using Ajax like:- Google Map for displaying maps, Facebook, YouTube, Gmail and others. 
 
What is JQuery and its used? 
JQuery provides the methods to Ajax functionality and with the help of Ajax and JQuery, We can send and receive the text, HTML, JSON, XML using both GET and POST methods.

we can use this directly from the Google and we can save it into the folder too. 
Now,
How to start JQuery basics after adding the JQuery file linking. 
 
1). First Syntax: -  
<pre class="brush:php;">
$(document).ready(function(){
 
// your function will take here.
 
});
</pre>
This is the basic syntax for understanding JQuery and function will execute once when the page is loaded. 
 
2. Notations : 
<pre class="brush:php;">
<button id="pressed_button">Press This Button Me</button>
 
<form class="form1"></form>
</pre>
In the above example, we used id = "button" - In JQuery we use # sign and for class = "form1" as . (dot) sign. 
 
3. Basic Function in JQuery: - 
<pre class="brush:php;">

$(".form1").submit(function(){
 
// This form will submit when form will submit. Then all the values will automatically submit into the associated fields.
 
});

$("#button1").click function(){
 
// In this Code will execute after clicking trigger button.
 
});
</pre>
<div>
<div>
4. How to get value from the text box and other fields :-</div>
<pre class="brush:php;">
$("#textbox_id").val();
</pre>
This syntax will retrieve the value from the input field.

</div>

<div>

5. How to get all form values :-
<div>
If we are getting value from the one field then we have to use .val() but if we are fetching multiple values from the form then we have to use.</div>
</div>
<pre class="brush:php;">

$("#form1").serialize();
</pre>
<div>
 .serialize() :  With the help of serialize() function we get all the values in serial ways with out missing any field value.</div>
<div>
</div>
<div>
</div>

<pre class="brush:php;">
$.ajax({
 type:"POST",
 url:"php_url_here.php",
 data:data,
 
 success:function(data)
 {
 $("#result_div_here").html(data);
 }
});
return false;
</pre>
 Now, We are using all the syntax within one form :-

echo $state."<br-->";
	echo $country;
 
}
?>
</pre>
