set_time_limit in php, set_time_limit in php5, why set_time_limit?

WHY set_time_limit ?
It is used to run the scripts in the file for a particular amount of time. If we just put set_time_limit(1) then the setting will allow the file to run the script for 1 second and if the time exceeds then it will throw the fatal error

Set_time_limit(0) – No time limit will be set, but I didt checked my MAX_EXECUTION_TIME, if there is still problem in the set_time_limit please check with the MAX_EXECUTION_TIME in the php.ini settings.

Let us check some examples
set_time_limit(0);
function ran()
{
$i=100000;
for ($j=0;$j<$i;$j++)
{
echo $j;
}
}
$gg=ran();
?>
>>>>> WONT THROW ANY ERROR


set_time_limit(1);
function ran()
{
$i=100000;
for ($j=0;$j<$i;$j++)
{
echo $j;
}
}
$gg=ran();
?>

>>>>>> HERE WE SET THIS TO 1 SECOND BUT THE SCRIPT NEEDS TO RUN A LOOP FOR 100000 SO IT WILL THROW THE ERROR LIKE BELOW
Fatal error: Maximum execution time of 1 second exceeded in ------------------------------------------------------------------------

Creating multiple like in a dynamic php page

Creating multiple like in a dynamic php page

1) Create the FB like code

2) Two formats

<.script src="http://connect.facebook.net/en_US/all.js#xfbml=1"><.fb:like href="http://*****/fb_like.php" show_faces="true" width="450" font="verdana">

<.iframe src="http://www.facebook.com/plugins/like.php?href=http%3A%2F%2F*******%2F******%2Ffb_like.php&layout=standard&show_faces=true&width=450&action=like&font=verdana&colorscheme=light&height=80" scrolling="no" frameborder="0" style="border:none; overflow:hidden; width:450px; height:80px;" allowTransparency="true">

3) I just used the first method

<.script src="http://connect.facebook.net/en_US/all.js#xfbml=1">

<.fb:like href="http://*****/fb_like.php?id=1" show_faces="true" width="450" font="verdana">

<.fb:like href="http://*****/fb_like.php?id=2" show_faces="true" width="450" font="verdana">

<.fb:like href="http://*****/fb_like.php?id=3" show_faces="true" width="450" font="verdana">

<.fb:like href="http://*****/fb_like.php?id=4" show_faces="true" width="450" font="verdana">

Add Search form in wordpress

<...........form method='get' id='searchform' action='<.....?php bloginfo('home'); ........?..>/'>
<......div>
<........input type='text' size='18' value=' ' name='s' id='s' />
<.....input type='submit' id='searchsubmit' value='Search' class='btn' />
<....../div>

Wordpress add small description in the index page or the page you want to show

This is the function in your template function.php

if(!function_exists('getPageContent'))
{
function getPageContent($pageId,$max_char)
{
if(!is_numeric($pageId))
{
return;
}
global $wpdb;
$nsquery = 'SELECT DISTINCT * FROM ' . $wpdb->posts .
' WHERE ' . $wpdb->posts . '.ID=' . $pageId;
$post_data = $wpdb->get_results($nsquery);
if(!empty($post_data))
{
foreach($post_data as $post)
{
$text_out=nl2br($post->post_content);
$text_out=str_replace(']]>', ']]>', $text_out);
$text_out = strip_tags($text_out);
return substr($text_out,0,$max_char);

}
}
}
}


and just have the code where ever you want to have

<....?php echo getPageContent(39,65); .....?>
39 is the page ID

and 65 is the character set
