note 30822 deleted from function.preg-replace by sniper

Note Submitter: checat@chat.ru ---- It should be noted in the manual, that when backreference substitution is not desired, but $replacement text can contain backslashes and dollar signs, you should ALWAYS use an additional function call to ADD SLASHES TO REPLACEMENTS. $replace='I have $350 in my hand!'; $text="He says, 'TEXT'"; echo preg_replace('|TEXT|',$replace,$text); will output He says, 'I have 0 in my hand!' $35 is counted as backreference and is substituted with null string. But: echo preg_replace('|TEXT|',addcslashes($replace,'\\$'),$text); He says, 'I have $350 in my hand!' That call to addcslashes() converts single backslash to double backslash and dollar to backslash-dollar, preg_replace() always strips additional slashes only from \ and $ in $replacement.
