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

Clauses

Warranty disclaimer

THIS SOFTWARE IS PROVIDED BY THE PHP DEVELOPMENT TEAM ``AS IS'' AND ANY EXPRESSED OR IMPLIED WARRANTIES, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE ARE DISCLAIMED.

Limitation of liability

IN NO EVENT SHALL THE PHP DEVELOPMENT TEAM OR ITS CONTRIBUTORS BE LIABLE FOR ANY DIRECT, INDIRECT, INCIDENTAL, SPECIAL, EXEMPLARY, OR CONSEQUENTIAL DAMAGES (INCLUDING, BUT NOT LIMITED TO, PROCUREMENT OF SUBSTITUTE GOODS OR SERVICES; LOSS OF USE, DATA, OR PROFITS; OR BUSINESS INTERRUPTION) HOWEVER CAUSED AND ON ANY THEORY OF LIABILITY, WHETHER IN CONTRACT, STRICT LIABILITY, OR TORT (INCLUDING NEGLIGENCE OR OTHERWISE) ARISING IN ANY WAY OUT OF THE USE OF THIS SOFTWARE, EVEN IF ADVISED OF THE POSSIBILITY OF SUCH DAMAGE.

Additional clauses

4. Products derived from this software may not be called "PHP", nor may "PHP" appear in their name, without prior written permission from group@php.net. You may indicate that your software works in conjunction with PHP by saying "Foo for PHP" instead of calling it "PHP Foo" or "phpfoo" 5. The PHP Group may publish revised and/or new versions of the license from time to time. Each version will be given a distinguishing version number. Once covered code has been published under a particular version of the license, you may always continue to use it under the terms of that version. You may also choose to use such covered code under the terms of any subsequent version of the license published by the PHP Group. No one other than the PHP Group has the right to modify the terms applicable to covered code created under this License.

Promotion specification

6. Redistributions of any form whatsoever must retain the following acknowledgment: "This product includes PHP software, freely available from <http://www.php.net/software/>".

Review

Written from the license text by: Giray Havur
Written on: 2026-09-15
Second review: not yet done
Record changed since this review: yes (version 2, 2026-09-24)
Findings: 9 recorded, 7 applied to the record, 1 proposed

Models version 3.01 of the PHP licence, the successor of the PhpLicense30 record. It is a BSD style licence with two name clauses and a mandatory acknowledgement in redistributions. Nothing here is legal advice.

9 findings

major Rubric 3 odrl:permission applied

The grant reads "Redistribution and use in source and binary forms, with or without modification, is permitted provided that the following conditions are met", so the record carries the BSD permission set: reproduce, distribute, modify, derive, display, present, commercial use, derivative works, modified works and the distribution fee.
major Rubric 4 odrl:prohibition applied

Clause 3 states 'The name "PHP" must not be used to endorse or promote products derived from this software without prior written permission' and clause 4 bars the word from product names, so dalicc:promote is a prohibition. Clause 5 ends "No one other than the PHP Group has the right to modify the terms applicable to covered code created under this License", which is modelled as a dalicc:ChangeLicense prohibition.
major Rubric 5 odrl:duty applied

Clauses 1 and 2 give cc:Attribution and cc:Notice on odrl:distribute, odrl:modify and odrl:derive. Clause 6 requires that "Redistributions of any form whatsoever must retain the following acknowledgment", which is modelled as a dalicc:addStatement duty on odrl:distribute. The existing PhpLicense30 record instead prohibits dalicc:addStatement, which reads the same term in the opposite sense; asserting both would have been reported by the consistency check as a duty that can never be discharged.
major Rubric 6 dalicc:PromotionSpecification applied

The exact acknowledgement of clause 6 is kept in dalicc:PromotionSpecification, as on the PhpLicense30 record, and this is the wording that changed between 3.0 and 3.01: "This product includes PHP software, freely available from <http://www.php.net/software/>". Clauses 4 and 5 are quoted in dalicc:additionalClauses, and the warranty and liability sentences are split into their own predicates.
info Rubric 7 cc:jurisdiction applied

The text names no legal system and sets no term, so cc:jurisdiction is dalicc:worldwide and dalicc:validityType is dalicc:perpetual.
gap Rubric 8 dalicc:additionalClauses proposed

Clause 5 lets the licensee keep using the version received or move to any later version published by the PHP Group. That is the same shape as the GNU or-later option, for which the review added dalicc:orLaterVersionOption as a property of the record; it is not applied here because the library uses it only on the four GNU records so far. Proposed action: apply dalicc:orLaterVersionOption "true" to this record and to PhpLicense30.
info Rubric 9 record none

The consistency check of app.services.composer with the dependency graph dg_default returned an empty conflict list.
major Rubric 10 record applied

Diffed against licensedata/licenses/PhpLicense30.ttl rather than read in full. The textual difference is confined to the acknowledgement wording of clause 6 and the name clause of clause 4. The modelled differences are deliberate: this record turns dalicc:addStatement from a prohibition into a duty, drops the unsupported cc:ShareAlike prohibition, drops the odrl:grantUse and dalicc:chargeLicenseFee permissions the text does not grant, and adds dalicc:ModifiedWorks. The existing record was not edited.
major Rubric 3 odrl:permission applied

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 earlier reading wrote 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.

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.
