In fact, "A" option is equal to "^" + patern.
If I don't misunderstand, "A" option should be equal to "^" + patern + "$"

You misunderstood:

echo preg_replace("/[a-z]{4}/A", "foo", "1fred24");
-> 1fred24
echo preg_replace("/[a-z]{4}/A", "foo", "fred24");
-> foo24

echo preg_replace("/[a-z]{4}/", "foo", "fred24");
-> foo24
echo preg_replace("/[a-z]{4}/", "foo", "1fred24");
-> 1foo24

Sorry, it's a mistake in the french documentation !
"it is constrained to match between the start to the end of the string"

Thus, it's a bug in the documentation's translation.

The french translation have been fixed in CVS, no need to open a new bug. sorry for the time wasted...
