PHP 4 is a major release of a widely used open-source scripting language originally created by Rasmus Lerdorf and developed by The PHP Group with significant contributions from Zend Technologies. It introduced a revamped execution engine and expanded capabilities that influenced web development stacks during the early 2000s, competing with technologies promoted by Microsoft, Apache Software Foundation, Netscape Communications Corporation, and agencies such as National Institute of Standards and Technology. The release impacted projects involving MySQL AB, PostgreSQL Global Development Group, Oracle Corporation, and hosting providers like DreamHost and GoDaddy.
History
The project evolved from earlier scripting efforts by Rasmus Lerdorf and attracted contributors including Zeev Suraski and Andi Gutmans of Zend Technologies, alongside developers associated with organizations such as Free Software Foundation, Open Source Initiative, Mozilla Foundation, and academic institutions like Massachusetts Institute of Technology and Stanford University. Early adoption intersected with platforms and servers from Apache Software Foundation, Netscape Communications Corporation, Microsoft, and vendors such as IBM, Sun Microsystems, HP, Dell, and Oracle Corporation. The community and corporate support drew interest from projects like MySQL AB, PostgreSQL Global Development Group, SQLite Consortium, cPanel, and hosting providers including Rackspace, BlueHost, and 1&1 Ionos.
Contributors and advocates discussed the language at conferences hosted by O’Reilly Media, Linux Foundation, USENIX, SIGPLAN, ACM, Gartner, Forrester Research, and university events at Harvard University, University of California, Berkeley, and Carnegie Mellon University. Important ecosystem collaborations involved GNU Project, OpenBSD, FreeBSD, and commercial integrations from Microsoft with Internet Information Services and vendors like Zend Technologies.
Features and Architecture
The release introduced a redesigned execution engine created by Zeev Suraski and Andi Gutmans, enabling features relevant to interactions with databases such as MySQL AB and PostgreSQL Global Development Group and protocols implemented by ICANN-registered services and infrastructure companies like Akamai Technologies. Language constructs influenced integrations with Apache Software Foundation modules, FastCGI implementations associated with F5 Networks and Nginx, Inc., and commercial toolchains from IBM and Microsoft.
Built-in extensions and APIs supported connectivity to systems from Oracle Corporation, IBM, Sybase, and open projects such as SQLite Consortium and LDAP directories used by Microsoft and Sun Microsystems. Support for templating and web frameworks affected projects like Drupal, Joomla!, WordPress, phpBB, MediaWiki, and content management companies including Acquia and Automattic.
Performance and Zend Engine II
The engine rework, often associated with the team at Zend Technologies, brought improvements comparable to optimizations promoted by organizations such as Intel Corporation, AMD, Red Hat, Canonical (company), and database vendors like Oracle Corporation and MySQL AB. These changes influenced deployment on operating systems from Microsoft Windows NT, Various BSDs, Solaris (operating system), and containerization trends later adopted by Docker, Inc. and orchestration by Kubernetes contributors like Google.
Performance discussions referenced benchmarking tools and standards from groups such as SPEC, Phoronix Media, and enterprises like Amazon Web Services and Rackspace, and informed tuning practices used by administrators from cPanel, Plesk (software), and managed hosting providers like Liquid Web.
Security and Vulnerabilities
Security issues discovered during the lifecycle were addressed with advisories from organizations including CERT Coordination Center, Open Web Application Security Project, National Security Agency, and coordination with vendors such as Red Hat, Debian Project, Canonical (company), Microsoft Security Response Center, Oracle Corporation, and SUSE. Patches and mitigations were distributed through channels involving Linux Foundation distributions, FreeBSD, OpenBSD, Gentoo, and packaged by commercial vendors like IBM and HP.
Incidents prompted discussions at conferences hosted by USENIX, Black Hat (conference), DEF CON, and security firms including Symantec, Kaspersky Lab, McAfee, and Trend Micro. Collaboration on secure coding and auditing involved academic groups from Stanford University, University of Cambridge, and ETH Zurich.
Version History and Releases
Maintenance and point releases were coordinated by The PHP Group with contributions from Zend Technologies, community members from repositories mirrored by SourceForge, GitHub, Inc., and distributions maintained by Debian Project and Red Hat. Release announcements featured in outlets like Slashdot, ZDNet, InfoWorld, Wired (magazine), and reports by analysts at Gartner and Forrester Research.
Packaging and binary distributions were provided by commercial hosting control panels including cPanel and Plesk (software), and integrations offered by vendors such as IBM, Oracle Corporation, Microsoft, and Amazon Web Services.
Adoption and Legacy
Adoption was widespread among projects such as WordPress, Drupal, Joomla!, phpBB, MediaWiki, and commercial platforms from Shopify, Magento (company), and Salesforce integrations. Hosting providers including GoDaddy, DreamHost, BlueHost, Rackspace, and 1&1 Ionos supported deployments, and developer ecosystems formed around communities hosted by Stack Overflow, GitHub, Inc., SourceForge, Reddit (website), and Slashdot.
The release influenced later language design and tooling from organizations like Facebook, Inc. with projects such as HHVM, and academic work at MIT, Stanford University, and Carnegie Mellon University. Historical analyses and retrospectives appeared in publications by O’Reilly Media, ACM, IEEE Computer Society, and technology news sites like The Verge, TechCrunch, and Ars Technica.
