array_walk debug example
Shows how to use the array_walk function to debug and print an array in a human readable format.
function debug_val($val, $key='', $depth=0) {
if (is_array($val)){
// call this function again with the "sub-array":
array_walk($val, 'debug_val', $depth+5);
}
else {
// if we hit a string or bool, etc. then print it:
print str_repeat(' ', $depth);
print '<span style="color: blue;">' . $key . '</span>: ';
print var_export($val, true);
print "<br/>\n";
}
}
/*example-start*/
// setup the test array
$array = array(
'php',
'cool',
array('foo', 1,2,3, array('mixed' => 'bar')),
'php' => 'array',
'yes' => true, 'no' => false
);
// debug the array
debug_val($array);
/*example-end*/
