PHP examples: print_r()

bool print_r(mixed)

class Mix { private $a = array('A' =gt; 'alpha', 'B' =gt; 'beta', 'G' =gt; 'gamma'); private $s = 'text'; private $n = NULL; private $e = ''; } $mix = new Mix(); print_r($mix); // Note that unlike var_dump print_r indicates a null value and an empty string in the same way

string print_r(mixed, bool)

class Mix { private $a = array('A' =gt; 'alpha', 'B' =gt; 'beta', 'G' =gt; 'gamma'); private $s = 'text'; private $n = NULL; private $e = ''; } $mix = new Mix(); $content = print_r($mix, TRUE); echo "Content of variable \$mix:\n\n$content\n";
