How to do basic natural language generation using PHP
Jun 22, 2023 am 11:05 AM
Natural language generation is an artificial intelligence technology that converts data into natural language text. In today's big data era, more and more businesses need to visualize or present data to users, and natural language generation is a very effective method. PHP is a very popular server-side scripting language that can be used to develop web applications. This article will briefly introduce how to use PHP for basic natural language generation.
- Introduction of natural language generation library
The function library that comes with PHP does not include the functions required for natural language generation, so we need to introduce some PHP natural language generation libraries . Among the more commonly used ones are:
- SimpleNLG: used to generate English natural language text.
- TextGen: used to generate some simple natural language text.
These libraries are usually provided as PHP extensions, so you need to install them and include them in your code.
- Create templates
Before natural language generation, it is usually necessary to define some templates. A template is a text containing placeholders that will be replaced with actual data in the code. For example, here is a simple template:
在{{地點(diǎn)}}出現(xiàn)了{(lán){數(shù)量}}只{{動(dòng)物}}，它們擠滿了{(lán){人群}}。This template contains three placeholders: place, quantity, and animal. In the code, we will replace these placeholders with actual data.
- Generate text using PHP library
To generate natural language text using PHP library, we need to perform the following steps:
- Create a generate device object.
- Use object methods to set some parameters, such as templates, data, etc.
- Call the generation method to get the final natural language text.
The following is a sample code using the SimpleNLG library:
use simplenlg rameworkSPhraseSpec;
use simplenlglexiconXMLLexicon;
use simplenlg
lxsentencesRealiser;
$lexicon = new XMLLexicon();
$realiser = new Realiser($lexicon);
$sentence = new SPhraseSpec();
$sentence->setSubject("你");
$sentence->setVerb("吃");
$sentence->setObject("蘋(píng)果");
$text = $realiser->realiseSentence($sentence);In this example, we use the SimpleNLG library to generate a simple English sentence, "You ate the apple" . First, we create an XML thesaurus object and a Realiser object. Then, we create an SPhraseSpec object to represent the sentence we want to generate, setting its subject, predicate, and object. Finally, we call the realizeSentence method of the Realiser object to get the final English sentence.
- Replace placeholders
Once we have the natural language text, we need to replace the placeholders with actual data. For example, if we use the template defined above, we can replace the placeholder like this:
$template = "在{{地點(diǎn)}}出現(xiàn)了{(lán){數(shù)量}}只{{動(dòng)物}}，它們擠滿了{(lán){人群}}。";
$data = [
"地點(diǎn)" => "動(dòng)物園",
"數(shù)量" => 10,
"動(dòng)物" => "大象",
"人群" => "游客"
];
$text = str_replace(array_map(function($key) { return "{{{$key}}}"; }, array_keys($data)), array_values($data), $template);In this code, we define a data array containing the actual data that we want to replace the placeholder with. Then, we use the str_replace function to replace the placeholder with data. Notice that we used the array_map and array_keys functions to generate an array of placeholders, and the array_values ??function to get the values ??from the data array.
- Generate natural language text
Finally, we can combine the above steps to achieve natural language generation. For example, we can reference data in the database in the template:
$template = "{{城市}}長(zhǎng){{長(zhǎng)度}}公里，共有{{人口}}人。";
$query = "SELECT * FROM cities WHERE name='上海'";
$data = $pdo->query($query)->fetch();
$text = str_replace(array_map(function($key) { return "{{{$key}}}"; }, array_keys($data)), array_values($data), $template);
echo $text;In this example, we define a query statement to obtain information about the city of Shanghai from the database. We then combine the obtained data with the template, use the str_replace function to replace the placeholders with actual data, and finally generate natural language text.
Summary
This article introduces how to use PHP for basic natural language generation, including creating templates, using PHP libraries to generate text, replacing placeholders, and generating natural language text. Although these techniques are only part of natural language generation, they are very useful for handling some basic natural language text rendering tasks. At the same time, attention should also be paid to data accuracy and security to avoid leaking sensitive information.

PHP calls AI intelligent voice assistant PHP voice interaction system construction
Jul 25, 2025 pm 08:45 PM
User voice input is captured and sent to the PHP backend through the MediaRecorder API of the front-end JavaScript; 2. PHP saves the audio as a temporary file and calls STTAPI (such as Google or Baidu voice recognition) to convert it into text; 3. PHP sends the text to an AI service (such as OpenAIGPT) to obtain intelligent reply; 4. PHP then calls TTSAPI (such as Baidu or Google voice synthesis) to convert the reply to a voice file; 5. PHP streams the voice file back to the front-end to play, completing interaction. The entire process is dominated by PHP to ensure seamless connection between all links.
How to use PHP to build social sharing functions PHP sharing interface integration practice
Jul 25, 2025 pm 08:51 PM
The core method of building social sharing functions in PHP is to dynamically generate sharing links that meet the requirements of each platform. 1. First get the current page or specified URL and article information; 2. Use urlencode to encode the parameters; 3. Splice and generate sharing links according to the protocols of each platform; 4. Display links on the front end for users to click and share; 5. Dynamically generate OG tags on the page to optimize sharing content display; 6. Be sure to escape user input to prevent XSS attacks. This method does not require complex authentication, has low maintenance costs, and is suitable for most content sharing needs.

Jul 25, 2025 pm 07:21 PM
PHP does not directly perform AI image processing, but integrates through APIs, because it is good at web development rather than computing-intensive tasks. API integration can achieve professional division of labor, reduce costs, and improve efficiency; 2. Integrating key technologies include using Guzzle or cURL to send HTTP requests, JSON data encoding and decoding, API key security authentication, asynchronous queue processing time-consuming tasks, robust error handling and retry mechanism, image storage and display; 3. Common challenges include API cost out of control, uncontrollable generation results, poor user experience, security risks and difficult data management. The response strategies are setting user quotas and caches, providing propt guidance and multi-picture selection, asynchronous notifications and progress prompts, key environment variable storage and content audit, and cloud storage.
