Include a page from url in php

                                   This article is to describe how to include a page from other web site to our php page.
                                php include url is not so simple as include a file in your site. We can edit web pages  by including it to our php page.
     

                                   php include external url  is not use include()  or  require() methods of  php  , which are used for local inclusion of  pages in our site.


    If we want to use that     we may use allow_url_include php for that.
     Here I am using  file_get_contents()   for this purpose.
   
     Code
   

<?php

  $cnt=file_get_contents('http://www.gmail.com');
  echo $cnt;
  echo "<div style=\" position:absolute;left:150px;top:50px \">
  <h1 style=\"color:red\">Successfully included By Sukesh B R
  </h1></div>";

?>

                     Here I am including the Gmail home page.  So give the URL ' http://www.gmail.com ' as
 parameter to file_get_contents() .         The return value from this is stored to the variable
 $cnt.     Then print this using echo statement.


 
                     Hence the Gmail page is displayed just like my local    html page.  Then I include a   <div>    in which a message    'Successfully included By Sukesh B R'       is displayed.I have use little css to display it in the top of gmail page.


Here is a sample screenshot of this page :-

                 



You can add javascript blocks to this page and access the elements of Gmail home page  and make changes in it with your like.You can add any other webpages just like this.

Extend maximum execution time of php script

Hi friends ,
today my discussion is about  extend maximum execution time of php script/page .
OR  solution for Fatal Error:Maximum execution time limit reached  when you run a php page .
OR change the maximum execution time of php script.OR increase the maximum execution time of
php script .
        We can change the maximum execution time by call a function set_time_limit().
       
       
Syntax

   void set_time_limit ( int $seconds );
    //set_time_limit(300);

                The parameter send to this specifies the maximum execution time in seconds.In the above code the maximum execution time is set to 300 seconds , that is 5 minutes.

This can also achieve by using the function ini_set() , like this ,

   ini_set('max_execution_time', 300);  

                Here also 300 is the maximum execution time in seconds.

Hope that this post is helpful to you.

Pass parameter to another page in PHP

I am discussing How to pass parameters as type GET to another page. OR Pass parameters as GET without using a form.OR Pass parameters through URL.

When we are using a form of method GET the values of text boxes enclosed in the form are
send to the action page through the URL.We can also send values through URL without a form.


If we want to pass a variable to another page when click a link

<a href="target.php?n1=5">Click Here</a>

If we want to pass more than 1 values seperate them with ' & '.

<a href="target.php"?n1=5&n2=10&name=sbr>Click Here</a>

In target.php the values can be retrieved just like form values send as GET method.
That is

$n1=$_GET["n1"];
$n2=$_GET["n2"];
$name=$_GET["name"];

When we want to send values of php variables , these code may be helpful

1.Pass a single value to another page

t1.php

<?php
$n1=5;
?>


<a href="target.php?n1=<?php echo $n1 ;?>">Click Here</a>

target.php

<?php
echo $_GET["n1"];
?>

2.Pass more than one value to another page

t1.php

<?php

$n1=5;

$n2=7;

?>

<a href="target.php?n1=<?php echo $n1 ;?>&n2=<?php echo $n2;?>">Click Here</a>

target.php

<?php
echo $_GET["n1"];
echo $_GET["n2"];
?>

You can see these two examples of using this  method here :-
