Matching with Greedy vs. Nongreedy Expressions

 
<?php 
$teststring = '"Hello" and "Goodbye."'; 
$greedyresult = preg_replace('/".*"/', '"***"', $teststring); 
$nongreedyresult = preg_replace('/".*?"/', '"***"', $teststring); 

echo "Original: $teststring\n"; 

echo "Greedy Replace: $greedyresult\n"; 

echo "Nongreedy Replace: $nongreedyresult\n"; 
?>
