In PHP, we often need to convert data in strings or files into arrays for processing, and PHPStream is a very convenient and practical tool.
PHPStream is a text and binary data stream processing mechanism of PHP, which can convert data in different formats into arrays. PHPStream is mainly used for reading and writing files and network protocol data, and can also be used as any data type that implements the iterator interface (Iterator), such as arrays, objects, etc.
PHPStream is similar to stream processing mechanisms in other programming languages, such as Java's IO stream. It can be used together with PHP's data operation functions (such as fopen, fread, fclose, etc.) to conveniently complete the processing of file and network protocol data. It can be manipulated just like an array using methods in the PHPStream class.
This article will demonstrate how to use PHPStream to convert a data stream into an array.
Preparation
Before starting, you need to install the PHP environment. It is recommended to use PHP 7.0 and above. Then set allow_url_fopen=On in the php.ini file so that data can be read from the network.
Usage method
- Open the data stream through the fopen function
Use the fopen function to open a network file stream and set the file reading mode to "Only read"(r) mode.
$stream = fopen('http://www.example.com', 'r');
- Use the stream_get_contents function to obtain the data stream content
Use the stream_get_contents function to read the entire data stream into a string variable.
$content = stream_get_contents($stream);
- Use the json_decode function to convert the string content into an array
Use the json_decode function to convert the string content into an array format.
$array = json_decode($content, true);
The above three steps can convert a network file stream into an array format. The final code is as follows:
$stream = fopen('http://www.example.com', 'r');
$content = stream_get_contents($stream);
$array = json_decode($content, true);
Let’s briefly talk about the implementation method:
Through fopen The function opens a network file stream and sets the file reading mode to "read-only" (r) mode.
Use the stream_get_contents function to read the entire data stream into a string variable.
Use the json_decode function to convert the string content into array format.
Summary
By using PHPStream, we can easily convert the data stream into array format for convenient processing. If you want to know more about PHPStream, you can check out the official PHP documentation. Hope this article is helpful to you.
