NAME
string_append - Fast string concatenation.
PROTOTYPE
string_append ( &$value, ... ) ;
DESCRIPTION
Appends series of values to the specified string.
PARAMETERS
$value (string) -
String where to append values.
$... (mixed) -
Any argument that can be converted to a string and appended to $value.
NOTE
This code is theorically faster than the inline string-catenation operator, except that calling a
PHP_FUNCTION() has a cost.
When catenating 100 000 times a set of value takes 170ms using the catenation operator, it takes 615ms
for string_append(), 535 of them being consumed just by calling the PHP_FUNCTION().
