i use this structure a lot for debugging. i always place the call to 'debugfunc' at the
start of any function which i want to debug. the square brackets in the echod output are useful to
see if there is accidental whitespace within string variables passed to anyfunc. if anyone can
suggest a better way of passing the names of the arguments to debugfunc i would appreciate it. as it
is works fine, but its not very universal...
<?php
anyfunc('val1','val2','val3');
function anyfunc($arg1, $arg2, $arg3)
{
debugfunc(__FUNCTION__, '$arg1, $arg2, $arg3', func_get_args());
/*do useful non-debugging stuff*/
}
function debugfunc($name, $arg_names, $arg_vals)
{
echo "begin function [$name]. ";
$arg_names_array = explode(',', $arg_names);
foreach($arg_names_array as $k => $v)
{
$v = trim($v);
echo "$v: [$arg_vals[$k]] ";
}
echo "\n";
}
//output:
//begin function [anyfunc]. $arg1: [val1] $arg2: [val2] $arg3: [val3]
?>
