Detecting SQL Injection in PHP Using the Cloudmersive Security API

Websites that directly accept raw SQL query input are frequent targets for SQL injection (SQLI) attacks because their interfaces lack proper protection.

If input text is not properly sanitized before executing a SQL database query, attackers can easily exploit the vulnerability to steal sensitive data. The following PHP code example demonstrates how to call a free Cloudmersive API that checks whether the input contains SQL injection risks, allowing the system to block such attacks before any database operation is performed.

To install the client SDK via Composer, run the following command:

composer require cloudmersive/cloudmersive_security_api_client

To enable the SQLI threat‑scanning feature, copy the provided PHP code snippet into your project:

<?php
require_once(__DIR__ . '/vendor/autoload.php');

// Configure API key authorization: Apikey
$config = Swagger\Client\Configuration::getDefaultConfiguration()->setApiKey('Apikey', 'YOUR_API_KEY');

$apiInstance = new Swagger\Client\Api\ContentThreatDetectionApi(
    new GuzzleHttp\Client(),
    $config
);
$value = "value_example"; // string | user‑provided text input

try {
    $result = $apiInstance->contentThreatDetectionCheckSqlInjectionString($value);
    print_r($result);
} catch (Exception $e) {
    echo 'Exception when calling ContentThreatDetectionApi->contentThreatDetectionCheckSqlInjectionString: ', $e->getMessage(), PHP_EOL;
}
?>

All that is required is a free Cloudmersive API key, which grants up to 800 SQLI scans per month without any additional commitment.

No further code is needed; you can quickly add this essential content‑security layer to your PHP application to ensure safety and stability.
