Previous Comments: ------------------------------------------------------------------------ [2004-09-06 21:27:20] nlopess@php.net If I understand, this function should return the legth of the match. But it seems it has a bug, because it always return 1 if you don't pass the 3rd parameter. Or is it a feature that should be documented? <? echo ereg('foo', 'foo foo foo'); //1 echo ereg('foo', 'foo foo foo', $var); //3 echo ereg('foobar', 'foobar foo foo', $var2); //6 ?> Nuno ------------------------------------------------------------------------ [2004-08-29 18:10:00] liit at geeksbynature dot dk ereg() still only returns int(1) or (boolean)FALSE. I've expanded my test-script a bit: <?php $a = ereg("fo","fo"); // Simple test to see if documentation is right (it's not) $b = ereg("bar","foobarbar"); // Is it the position of the first result, that is returned ? (no) $c = ereg("foo","bar"); // A negative test (works) echo $a . ":" . gettype($a). "\n"; echo $b . ":" . gettype($b). "\n"; echo $c . ":" . gettype($c). "\n"; ?> Result: 1:integer 1:integer :boolean According to the docs, it should be: 2:integer 3:integer :boolean ------------------------------------------------------------------------ [2004-08-17 00:40:12] tomsommer@php.net This bug has been fixed in the documentation's XML sources. The changes may not appear immediately, since the online and downloadable versions of the documentation need some time to get updated. We would therefore like to ask for your patience in this matter. Thank you for the report, and for helping us make our documentation better. ------------------------------------------------------------------------ [2004-08-17 00:12:47] iliaa@php.net ereg() returns the length of the matched string on success, the documentation is wrong. ------------------------------------------------------------------------ [2004-08-16 20:57:24] liit at geeksbynature dot dk Description: ------------ The function ereg() either returns (boolean)FALSE or (int)1, and not (boolean)FALSE or (boolean)TRUE Reproduce code: --------------- echo gettype(ereg("foo","foo")); echo gettype(ereg("foo","bar")); Expected result: ---------------- boolean boolean Actual result: -------------- integer boolean ------------------------------------------------------------------------ -- Edit this bug report at http://bugs.php.net/?id=29712&edit=1
