In what ways can debugging techniques be effectively used in PHP to troubleshoot and resolve issues when creating a complex image gallery layout?

Issue: When creating a complex image gallery layout in PHP, there may be issues with the image positioning or styling that need to be debugged and resolved. Debugging Technique: Use PHP's var_dump() function to inspect variables and arrays to identify any incorrect values or missing data that may be causing layout issues in the image gallery. 

<?php
// Sample code to troubleshoot image gallery layout issues
$images = array(
    array("src" => "image1.jpg", "alt" => "Image 1"),
    array("src" => "image2.jpg", "alt" => "Image 2"),
    array("src" => "image3.jpg", "alt" => "Image 3")
);

// Output the contents of the $images array for debugging
var_dump($images);
?>
