In any web application, file handling plays a very important role. For different processes, we need to open and process the file. For creating, reading, uploading files, there are many functions in PHP. Any kind of manipulation in the file can be done in a very careful manner. Sometimes files could be deleted or accidentally code gets deleted in some working file, the hard drive could be filled with garbage data, the wrong file chosen for working, etc. likewise many critical situations can occur while handling the file. Therefore file handling is always done carefully.

In PHP there is a read file() function defined for reading a file.

1. fopen() function is used to open a file. The fopen() function defined with two parameters.

<?php

$file = fopen("file.txt",'w');

?>

The first parameter in fopen() function is the name of the specified file and the second parameter is the mode for the particular file either read (r) or write (w).

Write mode modify the content of the existing file or it can be used to create the file for the same name if the file does not exist.

• The (a) mode is used to write the content at the last of the page. The existing file is not deleted. The content can be added from last and the new file is created if the file does not exist.
• The (x) mode used to write the file but if the file does not exist then it returns false as an error.
• The (r+) command is used to read/write mode.
• The (w+) mode is used for write/ read mode and through this content can be modified or deleted. read() function is used to read from an open file.

2. fclose() function is used for closing an open file. For the good developer, it is always recommended that the file must close first after completing the work on the same file.

<?php

$file = fopen("file.txt", 'r');

fclose($file);

?>




 If we want to read a single line from a file then we use fgets() function.

After calling fget() function, the pointer points to the next line and the process must go on.

The feof() function plays the role when the end of file is reached. It plays an important role in looping.

The fgetc() function is used to read the character from a file.

After calling the fgetc() function for one character then it points to the next character.

PHP is a very easy language and has very many useful functions. By using these functions we can be handling the PHP file easily and efficiently. Therefore File handling in PHP is very beneficial and necessary.

Configuration 'testApi' is obsolete and has been replaced with 'testImplementation'.
It will be removed at the end of 2018. For more information see: http://d.android.com/r/tools/update-dependency-configurations.html

Solution:

Goto Gradle Scripts.

Then Goto build.gradle(Module: app)

"Configuration 'compile' is obsolete and has been replaced with 'implementation'.

Example :

If you using compile then show the configuration error just replace compile to implementation.

This is the old way of writing the dependency libraries (for Gradle version 2 and below):

dependencies with Warning in android studio 3.1

dependencies {

    compile fileTree(dir: 'libs', include: ['*.jar'])

    compile 'com.android.support:appcompat-v7:25.3.1'

    compile 'com.android.support:support-v4:25.3.1'

    compile 'com.android.support:design:25.3.1'

    compile 'com.google.code.gson:gson:2.6.2'

    compile 'com.squareup.retrofit2:converter-gson:2.1.0'

    compile 'com.squareup.okhttp3:logging-interceptor:3.4.1'

    compile 'com.github.channguyen:rsv:1.0.1'

    compile 'com.valdesekamdem.library:md-toast:0.9.0'

    compile 'com.google.android.gms:play-services-ads:11.0.4'

    testCompile 'junit:junit:4.12'

}

You have to Just Change the following words: 

1) compile to implementation where word compile is returned.

2) testCompile to testImplementation where testCompile is returned.

3) androidTestCompile to androidTestImplementation where androidTestCompile is return.

Check the solution for this Example

dependencies OK in android studio 3.1 | In Android Studio version 3.1 dependencies compile word is replaced to implementation. This is the new (right) way of importing the dependencies for Gradle version 3:

dependencies {

    implementation fileTree(dir: 'libs', include: ['*.jar'])

    implementation 'com.android.support:appcompat-v7:25.3.1'

    implementation 'com.android.support:support-v4:25.3.1'

    implementation 'com.android.support:design:25.3.1'

    implementation 'com.google.code.gson:gson:2.6.2'

    implementation 'com.squareup.retrofit2:converter-gson:2.1.0'

    implementation 'com.squareup.okhttp3:logging-interceptor:3.4.1'

    implementation 'com.github.channguyen:rsv:1.0.1'

    implementation 'com.valdesekamdem.library:md-toast:0.9.0'

    implementation 'com.google.android.gms:play-services-ads:11.0.4'

    testImplementation 'junit:junit:4.12'

}

 

If you Want to add a third-party library like retrofit and another library. Then you have to use the implementation Keyword not compile Keyword.

For Example:

This is wrong.

compile 'com.squareup.retrofit2:retrofit:2.4.0'

This is Right.

implementation 'com.squareup.retrofit2:retrofit:2.4.0'

Blockchain technology is a decentralized and distributed approach for recording digital assets in a ledger format. Distributed ledger technology is known as blockchain technology. Through the cryptographic hashing and distributed ledger, the blockchain technology makes the digital assets unaltered. It implies through this wonderful technology the distributed ledger history would not change. The best example of blockchain technology is Google docs as the document is created and transferred to many people. All have access to change or modify the document and these changes are reflected in the real-time scenario. In the blockchain technology, no one is locked for changes done by the other party.

This decentralization of the document makes everyone to access the data file at the same time. All the changes are completely transparent to each and every people to whom the google doc is shared. This approach of decentralization is called blockchain technology.

Blockchain is more complicated than Google docs. In the blockchain, digital assets are not copied or transferred. This allows real-time access, as the changes may reflect instantly.

Blockchain is trustworthy and promising technology. It helps in reducing risks from fraud.
Blockchain is a revolutionary technique. Blockchain is the whole process of sharing valuable data to others also if you do not trust them.

Blockchain consist of three major concepts: - 1. Blocks 2. Nodes 3. Miners. Every blockchain chain has built from multiple blocks. Each block has data and a 32-bit whole number is called the nonce. A nonce generated the cryptographic hash when the first block is created. Miners create blocks on a chain through processing called mining. Nodes are a very important part of distributed ledger via the nodes. Therefore, blockchain is the scalability of trustworthy technology.

GET & POST methods are superglobals which means they can easily access from any place anywhere. Get and Post method are very useful methods for form handling. Most of the developers prefer POST for sending form data. GET and POST, both methods are creating an array with key and value pairs. The name in the array is the form control field name the value is the entered data by the user.

GET & POST methods both are used as $_GET and $_POST. As they both are not required scope for their accessibility. We can access these methods anywhere in any function, any class or file as we do not need to do any functionality for the same.

If we simply say about $_GET is none other than an array of variables passed to script which is executing on that time via URL parameters.

The HTTP POST method is used in $_POST which is also an array of variables. When using Get method in form submission then the user information either names or values) is visible in URL to everyone. Get also has some specified limits of only 2000 characters i.e. it can send form data only within particular limits.

In GET it is possible to bookmark the page, as data is shown in  URL which is beneficial in some cases. GEt is always used for sending the data which is not private. As there is no security in getting because everything is displayed in URL. Hence sometimes we avoid Get while sending passwords and other private information.

On the other hand, information while sending with the POST method is not visible to the users. So, it is more secure than GET method.

 In the POST method, all the names and values are embedded in the HTTP request, as it is not visible to others. There is no specified limit for sending data. We can send an unlimited amount of characters while sending form data through the POST method.

As compared to the GET method POST supports advanced functionality.

In POST, while uploading files to the server it supports multi-part binary input. In the post, it is not possible to bookmark the page.

 In short, the secure method is the POST method for sending form data in comparison to the GET method.
