License-wide duties

This license states no duties that apply to the work as a whole.

What applies by default

The statements above are the library's reading of this license: each is marked with the sentence it rests on, or as a library convention where the text is not explicit. The statements below are the ones the DALICC reasoner supplies for acts the license says nothing about, from the default rules of the dependency graph it reasons with. Each one names the legal source it rests on. None of it is in the record.

No default rule of that graph reaches this license: it speaks about every act the rules are about.

Further terms

These are the things the license says about itself beyond the acts it permits, forbids and requires: when it ends, how long there is to put a breach right, which law governs it, and so on. A term that comes from the DALICC vocabulary links to its definition.

Or later version option
Yes

Verdict

Record changed since this review
yes (version 2, 2026-09-24)
Findings
8 recorded, 4 applied to the record, 2 proposed

The PHP license is a BSD-style permissive license with two name restrictions and a required acknowledgement. The record had the permissions and the trademark prohibition right but recorded neither the naming clause nor the acknowledgement, and had no SPDX id. All three were added. The share-alike prohibition has no support in the text.

8 findings

  • minor Rubric 1 spdx:licenseId applied

    Added PHP-3.0. Verified rather than assumed: cc:legalcode already points at the Open Source Initiative page that the SPDX entry lists under seeAlso, dct:alternative is "PHP-3.0", and the fetched text is version 3.0.

  • minor Rubric 6 dalicc:additionalClauses applied

    Clause 4, the naming restriction, was not recorded. Added, quoted.

  • minor Rubric 6 dalicc:PromotionSpecification applied

    Clause 6 requires a fixed acknowledgement in every redistribution. The Apache-1.1 record uses dalicc:PromotionSpecification for the same kind of clause; added here for consistency, quoted.

  • major Rubric 5 odrl:duty proposed

    Clause 4 also makes a rename duty: a derived product may not carry the PHP name. The Apache-1.1 record models the equivalent clause with dalicc:rename on odrl:modify. Proposed rather than applied because clause 4 is drafted as a prohibition on a name, not as an obligation to rename.

  • major Rubric 5 odrl:prohibition proposed

    cc:ShareAlike is prohibited although the six conditions say nothing about the terms a redistributor may choose. dalicc:addStatement is prohibited on the same empty basis. Both are template defaults.

  • info Rubric 4 odrl:prohibition none

    dalicc:promote is prohibited and clause 3 supports it: "The name \"PHP\" must not be used to endorse or promote products derived from this software without prior written permission."

  • gap Rubric 8 vocabulary none

    Clause 5 is a version-choice clause: covered code may always be used under the version it was published under or under any later version published by the PHP Group. That is the same "or later" mechanic as in the GNU family and no term expresses it. Proposed term: dalicc:orLaterVersionOption.

  • major Rubric 10 record applied

    Standard-license addition of 2026-09-15, decision 9: the record was corrected against its new siblings and versioned. The review's finding on family consistency and consolidation decision 7: the record prohibited dalicc:addStatement although clause 6 requires a statement to be retained, and prohibited cc:ShareAlike without support. Clause 6 reads 'Redistributions of any form whatsoever must retain the following acknowledgment: \"This product includes PHP software, freely available from <http://www.php.net/software/>\"', which is the dalicc:advertisingAcknowledgement duty, and clause 5 lets the licensee move to any later version the PHP Group publishes.

History

This license model has 2 versions. Version 2 is the one served today; every earlier version keeps its own address, so a conclusion drawn from one of them can still be checked against it.

  1. Version 2 current2026-09-24 Giray Havur

    The content review of 2026-09-15 added 2 clause texts and 1 identification detail and recorded the review state. Later changes brought it in line with its family and its text in the verification of 2026-09-15, permitted relicensing with the notice as a duty, recorded which sentence of the text each statement rests on and named the license the record itself is published under.

    • added permission dalicc:ChangeLicense with duties [dalicc:compliantLicense]

      Manual edit Permit relicensing on permissive licences; the notice clause is a duty, not a bar. Library convention 15: a licence that asks for no reciprocity and no source code asks only that the notice travels with the copy, which is a duty on the acts it governs and not a bar on putting the copy under other terms. dalicc:ChangeLicense is therefore a permission here, and the prohibition the record carried before is removed. The text reads: "Redistribution and use in source and binary forms, with or without modification, is permitted provided that the following conditions are met: 1. Redistributions of source code must retain the above copyright notice, this list of conditions and the following disclaimer." The permission carries the dalicc:compliantLicense duty, as Apache-2.0 does, because the notice has to survive the relicensing.

    • changed permission dalicc:ChangeLicense with duties [dalicc:compliantLicense]

      was permission dalicc:ChangeLicense with duties [dalicc:compliantLicense]

      Manual edit The statement is marked as a library convention, family rule 15: Permissive records permit relicensing: the text does not state it in as many words. Its duty dalicc:compliantLicense is marked as a library convention, family rule 15: Permissive records permit relicensing.

    • changed prohibition dalicc:promote

      was prohibition dalicc:promote

      Manual edit The statement now quotes the sentence of the licence text it rests on: "The name "PHP" must not be used to endorse or promote products derived from this software without prior written permission."

    • added dct:license <https://creativecommons.org/licenses/by/4.0/>

      Manual edit Every record is published under CC BY 4.0. cc:license names the record DALICC keeps of that licence; dct:license now names it by the address Creative Commons publishes it at, so that a consumer matching the canonical IRI finds it.
