How can debugging techniques such as var_dump and echo be utilized to identify and resolve issues in PHP script execution flow?

To identify and resolve issues in PHP script execution flow, debugging techniques such as var_dump and echo can be utilized to inspect variable values and output messages at different points in the script. By using var_dump, you can print out the type and value of a variable, helping you understand its current state. Echo statements can be used to output custom messages or variable values to the screen, allowing you to track the flow of execution and pinpoint any anomalies.

// Example PHP code snippet demonstrating the use of var_dump and echo for debugging

$variable = "Hello World";

// Using var_dump to inspect the variable
var_dump($variable);

// Using echo to output a message
echo "Variable value: " . $variable;
