When receving values from a form text field such as

 <INPUT name="hugo" type="text">

any entered ['] is preceedet with an [\] in the variable $hugo. Thus:

 [it's a shame] becomes "it\'s a shame".

1. I don't see any reason for it.

2. I tried to solve the problem using preg_replace:

 preg_replace('~\/\'~','\'',$hugo);

...without any effect.

 preg_replace('~\134\'~','/',$hugo);

indeed works fine! An error?!
