YOUR STARTING SEARCH

PHPDetected version below 8.0.0Refine to your marketThe search starts with PHP and a version limit below 8.0.0. Change the cutoff in Technologies → Version below, or add a language, domain extension, or keyword to focus on your market. Sites with unknown versions are excluded.
Open search and refine the filtersTurn a legacy PHP signal into an upgrade assessment
Choose the sites your team can support
Start with PHP versions below 8.0.0, then narrow to your market. Review the detected framework or CMS to assess whether the application fits your team’s experience.
Verify the runtime and compatibility work
Confirm the current PHP runtime with the site owner. Assess dependencies, framework support, custom code, and test coverage before estimating an upgrade.
Propose a scoped migration
Export your shortlist with Pro. Qualify the owner’s needs and plan compatibility fixes, staging checks, and deployment work around a suitable target PHP version.
A detected version starts the conversation
Public version signals may be incomplete, stale, or different from the runtime serving part of an application. A PHP version alone does not prove an exploitable vulnerability or establish purchase intent. Confirm the environment with the owner before recommending work.

Before you build your list
Which PHP versions does this search include?
It selects indexed, numeric PHP versions with a major version below 8: PHP 7.x and earlier. PHP 8.0.0 and later, unknown versions, and ambiguous version strings are excluded.
Can I change the PHP version cutoff?
Yes. Open Technologies in the search results and edit the Version below field under PHP. The limit is exclusive: entering 8.0.0 excludes PHP 8.0.0 itself. Clear the field to remove the limit.
Does this find every website running an older PHP version?
No. The list depends on Stackcrawler’s indexed websites and publicly detectable version signals. Sites that hide their PHP version will not appear in this version-filtered search.
Should I upgrade a prospect to PHP 8.0.0?
The cutoff defines the prospect search, not the recommended upgrade destination. Choose a currently supported target after checking the application, dependencies, and hosting environment.
Can I export the matching websites?
Pro supports website result exports within its plan limits. Advanced includes lead and contact data where available. Check pricing for current allowances.
