Hello all,
The following code line :
array_push($thi s->content, &$elt);
produces the following error :
Warning: Call-time pass-by-reference has been deprecated - argument
passed by value; If you would like to pass it by reference, modify the
declaration of array_push(). If you would like to enable call-time
pass-by-reference, you can set allow_call_time _pass_reference to true in
your INI file. However, future versions may not support this any longer.
in /home/sites/site77/web/lib/xml/General_tag.cla ss.php on line 56
What is the propest way to fix it ?
Thx, Thierry.
PS 1 : I can not modify the "online" php.ini file. I'm using PHP v4.1.2
online, and v4.2.0 on local for my tests.

Carved in mystic runes upon the very living rock, the last words of
Thierry of comp.lang.php make plain: Hello all,
The following code line :
array_push($thi s->content, &$elt);
Why would you want to do this? $elt is simply pushed onto the array; it
isn't modified in any way. Why are you trying to pass it by reference?

Phorm PHP Form Processor http://www.phorm.com/ The following code line :
array_push($t his->content, &$elt);
Why would you want to do this? $elt is simply pushed onto the array; it isn't modified in any way. Why are you trying to pass it by reference?
Because I use to do that :
$my_tag = &new General_tag();
$my_tag->set_tag_name(" toto");
$my_tag2 = &new General_tag();
$my_tag2->set-tag_name("toto 2");
// Here I use it
$my_tag->add($my_tag2 );
// Here it becomes important to have the reference.
// In general, done in an other function.
$my_tag2->set_tag_name(" toto 3");
with only array_push($thi s->content, $elt), the final tag_name of
my_tag2 is still "toto 2"...

To get around the call-time reference passing issue, simply create a
function that will do what you want. For instance, something like this
may work for your purposes:
function array_push_ref( &$target,&$valu e_array){
if(!is_array($t arget)){
echo 'ERROR: Target is not an array in function array_push_ref. ';
return FALSE;
}
if(is_array($va lue_array)){
foreach($value_ array as $val)
$target[]=$val
}
}else{
echo 'WARNING: Passed value is not an array, treating as single
value.';
$target[]=$value_array;
}
return TRUE;
}
