What does the is_final parameter in xml_parse () do?
I am working on creating a class for parsing xml and have to use this method from PHP called xml_parse
.
It has 3 parameters:
int xml_parse ( resource $parser , string $data [, bool $is_final = false ] )
According to the PHP manual is_final
, this means whether its last piece of data will be sent in this analysis, but what does that mean? is it something to do with resource $parser
? As far as I know, this function does not allow input data stream, thus my confusion.
Someone please explain what he is doing

is_final
means that if you are parsing the last line of yours $data
, you must set this parameter to true.
Also, the Dock has a note:
Entity errors are reported at the end of the parse. And will only show if the "end" parameter is TRUE
See sample below from w3schools
<?php
$parser=xml_parser_create();
function char($parser,$data)
{
echo $data;
}
xml_set_character_data_handler($parser,"char");
$fp=fopen("test.xml","r");
while ($data=fread($fp,4096))
{
xml_parse($parser,$data,feof($fp)) or
die (sprintf("XML Error: %s at line %d",
xml_error_string(xml_get_error_code($parser)),
xml_get_current_line_number($parser)));
}
xml_parser_free($parser);
?>
