note 56419 added to function.include

Script to determine the location of a file that I am trying to include. a. What is the path of the file in relation to the current directory, and assuming that the file name is relative to the scripts location? include(FindScriptRelativeToCurentDirectory(dirname(realpath (__FILE__))) . "relpath/myIncFile.php"); where "relpath/myIncFile.php" is the name of the file that you are trying to include relative to your script (the script where the include() resides). The path returned is terminated with a slash. b. What is the path of the file in relation to the current directory, and assuming that the file name is relative to the doc root? include(FindScriptRelativeToCurentDirectory("myFile", true, true)); the second parameter tells the function that myFile is relative to the doc root (instead of the executing script's path), and the second parameter tells the function that myFile contains a file name (it is not just a path). /* **** Get relative path of this file (relative to current directory) $scriptPathOrName - either the path or name of the script that you are trying to find. $scriptPathIsRelativeToDocRoot - if this is false, it is assumed that $scriptPathOrName is relative to the script currently executing. Otherwise, it is relative to doc root. $thisIsAFileName - If true, then $scriptPathOrName includes the file name. Otherwise, it is just a path. */ function FindScriptRelativeToCurentDirectory($scriptPathOrName, $scriptPathIsRelativeToDocRoot=false, $thisIsAFileName=false) { $currentPath = realpath ('.'); $commonPathPtr = 0; /* Find the character used to separate dir names (backslash in windows, forwardslash in Linux, etc.) */ $dirChar = ""; for ($i=0; $i < strlen($currentPath ); $i++) { if ($currentPath{$i} == '/' or $currentPath{$i} == '\\') { $dirChar = $currentPath{$i}; break; } } /* If script is relative to doc root, combine the two */ if ($scriptPathIsRelativeToDocRoot) { $rootPath = $_SERVER['DOCUMENT_ROOT']; if($rootPath{strlen($rootPath)-1} != $dirChar) { $rootPath .= $dirChar; } if ($scriptPathOrName{0} == '/' or $scriptPathOrName{0} == '\\') { $scriptPathOrName = substr($scriptPathOrName, 1, strlen($scriptPathOrName) - 1); } $scriptPathOrName = $rootPath . $scriptPathOrName; } /* because you may developing in different systems that where you are going to deploy, there may be a mix of backslashes and forwardslashes when combining the root path with a script name.
