PharFileInfo::setMetadata Sets file-specific meta-data saved with a file &reftitle.description; public voidPharFileInfo::setMetadata mixedmetadata PharFileInfo::setMetadata should only be used to store customized data in a file that cannot be represented with existing information stored with a file. Meta-data can significantly slow down the performance of loading a phar archive if the data is large, or if there are many files containing meta-data. It is important to note that file permissions are natively supported inside a phar; it is possible to set them with the PharFileInfo::chmod method. As with all functionality that modifies the contents of a phar, the phar.readonly INI variable must be off in order to succeed if the file is within a Phar archive. Files within PharData archives do not have this restriction. Some possible uses for meta-data include passing a user/group that should be set when a file is extracted from the phar to disk. Other uses could include explicitly specifying a MIME type to return. However, any useful data that describes a file, but should not be contained inside of it may be stored. &reftitle.parameters; metadata Any PHP variable containing information to store alongside a file &reftitle.returnvalues; &return.void; &reftitle.examples; setMetadata(array('user' => 'bill', 'mime-type' => 'text/plain')); var_dump($p['file.txt']->getMetaData()); } catch (Exception $e) { echo 'Could not create/modify phar: ', $e; } ?> ]]> &example.outputs; string(4) "bill" ["mime-type"]=> string(10) "text/plain" } ]]> &reftitle.seealso; PharFileInfo::hasMetadata PharFileInfo::getMetadata PharFileInfo::delMetadata Phar::setMetadata Phar::hasMetadata Phar::getMetadata
