Methods of Increasing file upload size in PHP

It often becomes a major headache to continue file uploading in PHP due to limitations in maximum file upload size. Increasing memory limits in PHP and increasing PHP upload size are two completely different worlds of determinations. Default option allows PHP upload size be limited between 2MB to 10MB. Most servers are developed on PHP scripts which make it open to initiate changes in upload limits. Errors are common with developers finding it hard to select higher upload sizes. We have given a few steps which can help to ensure increasing file upload size in PHP.


Configuration Options
The following configurations need to be set in order to prepare the increase in upload limitation. ‘upload_max_filesize’ is a command that ensures increasing the upload file size. ‘memory_limit’ allow developers to set maximum limits within the script. This allows the desired file size to be allocated. This is a very important command that helps preventing poorly written scripts to take up larger memories on servers. In order to erase memory limit directive for this command must be set to -1. post_max_size

Code that Ensures Increasing of File Upload Limit There are few common codes and commands that help in increasing file upload size in PHP> Given below are a few choices: php_value upload_max_filesize 40M php_value post_max_size 42M
Above mentioned command increases PHO file upload limit only if the server allows .htaccess to make changes in PHP configuration. .htaccess files are stored along with .php files in the same directory. Configuration can be modified for the folder that contains the file and all other sub-folders. A .htaccess file needs to be created in the directory of your choice and the process of configuration can be followed. The final step includes writing the above mentioned command that invariably implements the change.

Edit php.ini
Php.ini gets stored in /etc/php.ini or /etc/php.d/cgi/php.ini or /usr/local/etc/php.ini. These files need to be edited to increase the upload limit. # vi /etc/php.ini wil be the command for achieving this.
ini_set function is another way of achieving the means of increasing upload limit. The following command will ensure the right output. However before writing the below mentioned command php.ini must be changed:
ini_set('post_max_size', '64M');
ini_set('upload_max_filesize', '64M')
Recent PHP versions contain ini-settings as PHP_INI_PERDIR do not allow setting them into a script.

Common causes affecting file uploading in PHP
Setting memory limits affect file uploading in PHP. While working in WordPress ‘wp-config.php file’ needs to be modified to make changes in file uploading limit. PHP files not uploaded on ASCII will affect file uploading. All PHP file types such as .txt, .cfg, .sql, .html, .inc must be uploaded in ASCII mode. PHP settings must not be set to low values as it affects file uploading. Errors in version of files are another common cause affecting file uploading. Erroneous entry in Database data often affects PHP file uploading limit. Every single detail entered must be in order and checked multiple times. Server side script developed on PHP affects in increasing PHP file uploading.

Android default DatePicker show day/month/year fields but you have to customize this DatePicker as your requirements. Suppose that you want to show only month and year fields in android datepicker . To do this, you have to customize the Dialog DatePicker source code but it is not an easy task. In this tutorial I will show you a tricky way to solve this problem. Lets see how to show only month and year field in android DatePicker as a dialog.   Step to show only month and year fields in android date-picker: Some days ago I got this same problem and here I am trying to explain this in a sequential manner. I want to show a dialog datepicker when user click on an EditText. So if user click on EditText, A dialog datepicker will be invocked and it will show only month and year fields. To do this, at first we have to create a xml layout to hold the EditText fields. So create an android project and name it DatePickerExample. In the main.xml file just try to write this simple code....

How to construct a B+ tree with example

Image
A B+ tree contains n-1 search key values K1K2…….Kn-1 and have n pointers.   In a B+ tree the data are ordered  sequentially.  The leaf node may hold up to n pointers and must hold at least N/2 pointers. The root node must hold at least two pointers, unless the tree consists of only one node.  Now we construct a B+ tree. Construct a B+ tree for the following set of key values: (2,3,5,7,11,17,19,23,29,31) Assume that the tree is initially empty and values are added in ascending order. Construct a B+ tree where the pointer number is Four. Solution: When a node exceeds n-1 search key value then we split it into two nodes. First node contains (ceiling(n-1)/2) values.  2 nd node contains remaining node. Copy the smallest search key value of the second node to the parent node. Let's start, we know each node has N pointer and has N-1 search key values. In our example pointer number is 4, so the search key value is 4-1=3. So each node has 4 pointers and 3 search key val...

Conflict Serializability in database

Image
To maintains database state consistency we introduce serializability. Using serializability we can understand which schedule will ensure consistency, and which schedule will not. When we are capable of converting a concurrent schedule into a serial schedule then we cal it serializable schedule. A schedule is serializable if it is equivalent to a serial schedule. We divided this concepts into two parts 1. Conflict serializability  & 2. View serializability In this discussion I just clarify you the conflict serializability. Consider two instruction read, write and the data item A and B. When two instruction execute different data item such as read(A) and read(B), then we can swap the instruction without affecting the result of the schedule. But when the data item is equivalent to one another we need to consider following four condition.    a.   read (A ),    read ( A ).   they   don’t conflict.    b.   read ( Q),  ...
