<?php
/**
 * Clears the cache based on the command $cacheCmd.
 *
 * $cacheCmd='pages':   Clears cache for all pages. Requires admin-flag to
 * be set for BE_USER.
 *
 * $cacheCmd='all':     Clears all cache_tables. This is necessary if
 * templates are updated. Requires admin-flag to be set for BE_USER.
 *
 * $cacheCmd=[integer]: Clears cache for the page pointed to by $cacheCmd
 * (an integer).
 *
 * $cacheCmd='cacheTag:[string]':  Flush page and pagesection cache by given tag
 *
 * $cacheCmd='cacheId:[string]':  Removes cache identifier from page and page section cache
 *
 * Can call a list of post processing functions as defined in
 * $GLOBALS['TYPO3_CONF_VARS']['SC_OPTIONS']['t3lib/class.t3lib_tcemain.php']['clearCachePostProc']
 * (numeric array with values being the function references, called by
 * \TYPO3\CMS\Core\Utility\GeneralUtility::callUserFunction()).
 *
 * Note: The following cache_* are intentionally not cleared by
 * $cacheCmd='all':
 *
 * - cache_md5params:   RDCT redirects.
 * - cache_imagesizes:  Clearing this table would cause a lot of unneeded
 * Imagemagick calls because the size informations have
 * to be fetched again after clearing.
 *
 * @param string $cacheCmd The cache command, see above description
 * @return void
