SplFileInfo::getLinkTarget() fails .we have a filesymlink created  for a file (filesymbolic.txt)  and tried to read the target of the filesymlink created and it returns an error .This happens for Directory also.

When this Function used on accessing symlinks over remote share  it returns an error with 'Bad File Descriptor'.

Test script:
$filename = dirname(__FILE__)."\\filesymlink";
$filesyminfo =  new SplFileInfo($filename);

Expected result:
string(16) filesymbolic.txt

Actual result:
Fatal error: Uncaught exception 'RuntimeException' with message 'Unable to read link C:\Program Files (x86)\Apache Software Foundation\Apache2.2\htdocs\symlinktodir, error: No such file or directory' in C:\Program Files (x86)\Apache Software Foundation\Apache2.2\htdocs\getLinkTarget.php:5 Stack trace: #0 C:\Program Files (x86)\Apache Software Foundation\Apache2.2\htdocs\getLinkTarget.php(5): SplFileInfo->getLinkTarget() #1 {main} thrown in C:\Program Files (x86)\Apache Software Foundation\Apache2.2\htdocs\getLinkTarget.php on line 5
