PHP Error Monitoring

Actionable insights to resolve PHP performance bottlenecks and errors. See the full picture of any PHP exception with a clear workflow to create an efficient PHP debugging process.

Getting Started is Simple

Install the sentry/sentry package with Composer:

Click to Copy
composer require sentry/sentry

To capture all errors, even the one during the startup of your application, you should initialize the Sentry PHP SDK as soon as possible.

Click to Copy
Sentry\init(['dsn' => 'https://<key><project>' ]);

Quickly identify PHP performance issues and view full end-to-end distributed trace to see the exact, poor-performing API call and surface any related errors. Get the real-time data and detailed reporting you need to solve performance issues early.

PHP Error Monitoring with Complete Stack Traces

See local variables in the stack for prod errors, just like in your dev environment. Explore the full source code context with frame to function data. Filter and group PHP exceptions intuitively to eliminate noise.

Expose the important events that led to each PHP exception: warnings, past errors, custom breadcrumbs. Get a full view of releases so you can mark errors as resolved and prioritize live issues.

”As we ship code, which we do at least daily, I’m constantly staring at Sentry.”

Debugging Any PHP Exception

Aggregate errors by factors like request details, user ID, and app versions to see what’s new, a priority or a trend.

Assign custom key-value tags to reproduce the error environment specific to your application, business, and users.

Answer the most important questions: How actionable is the error? Can I snooze the alert?


Traditional logging provides you with a trail of events. Some of those events are errors, but many times they’re simply informational. Sentry is fundamentally different because we focus on exceptions, or in other words, we capture application crashes. We discuss in more detail here and on our blog.

Sentry supports every major language, framework, and library. You can browse each of them here.

You can get started for free. Pricing depends on the number of monthly events, transactions, and attachments that you send Sentry. For more details, visit our pricing page.

Sentry doesn’t impact a web site’s performance.

If you look at the configuration options for when you initialize Sentry in your code, you’ll see there’s nothing regarding minimizing its impact on your app’s performance. This is because our team of SDK engineers already developed Sentry with this in mind.

Sentry is a listener/handler for errors that asynchronously sends out the error/event to This is non-blocking. The error/event only goes out if this is an error.

Global handlers have almost no impact as well, as they are native APIs provided by the browsers.
