在PHP中处理其他程序员的复杂数组

Question

I am maintaining an OO PHP application that loads everything to $this array. When I do a var dump on $this to find out how to access a value, I get dozens of pages of output. Hunting down the array elements that I need is very time consuming

For example, if I want to find where Customer Territory is stored, I have to figure out the heirarchy of the array using print_r or var_dump and staring [ edit: and searching] ]at the output until I figure out the path.

for example: $this->Billing->Cst->Record['Territory']

Is there a better way to do this, or some tools/techniques that I can use. For instance, is there there quick way to find the path to variable ['Territory'] throughout the array directly?

Answer 1

Krumo is a graphical "var_dump" tool that may make navigation a tiny bit easier. Check out the "examples" section on the project page.

For searching in multi-dimensional arrays, this SO question may help you.

Answer 2

You could probably do ctr+F on the output instead of staring at it?

Just start with ctr+F: "Customer", "Territory" and all other names related to whatever you're searching.

Answer 3

function findInTree($var, $words) {
    $words = explode(' ', strtolower($words));
    $path = array();
    $depth = 0;
    $iterator = new RecursiveIteratorIterator(new RecursiveArrayIterator($var), RecursiveIteratorIterator::SELF_FIRST);
    foreach ($iterator as $key => $value) {
        if ($iterator->getDepth() < $depth) {
            unset($path[$depth]);
        }
        $depth = $iterator->getDepth();
        $path[$depth] = $key;

        if (is_string($key) && in_array(strtolower($key), $words)) {
            echo '<pre>', implode(' -&gt; ', $path), '</pre>';
        }
    }
}

findInTree($this, 'Customer Territory');

This function will walk through your object and look for any of the given words as a key.
