PHP array recursive output, how to solve

PHP array Recursive output
This post was last edited by ecshop528 on 2013-01-21 12:54:22

$ar = Array (' 0 ' =>array (' name ' = ' name1 ', ' age ' = ' age1 '), ' 1 ' =>array (' name ' = = ' name2 ', ' age ' = ' age2 ') ), ' 2 ' =>array (' name ' = ' name3 ', ' age ' = ' age3 '));

To use recursion, enter the following string



Name3-age3

Name2-age2

Name1-age1

$ar = Array (' 0 ' =>array (' name ' = ' name1 ', ' age ' = ' age1 '), ' 1 ' =>array (' name ' = = ' name2 ', ' age ' = ' age2 ') ), ' 2 ' =>array (' name ' = ' name3 ', ' age ' = ' age3 '));
Deep_child ($ar);
function Deep_child ($ar = Array ()) {
static $str = ';
static $i = 0;

if ($ar [$i]) {
Echo ';
$s =  $ar [$i] [' name ']. " -". $ar [$i] [' age '];
$i + +;
Deep_child ($ar);
Echo $s;
Echo ';

}
}

This kind of writing seems to be able to input, do not know if there is no other way to write.

------Solution--------------------
Static variables are not freely available.

$ar [0] = array (' 0 ' =>array (' name ' = ' = ' name1 ', ' age ' = ' age1 '), ' 1 ' =>array (' name ' = = ' name2 ', ' age ' = ') Age2 '), ' 2 ' =>array (' name ' = ' name3 ', ' age ' = ' age3 '));
$ar [1] = array (' 0 ' =>array (' name ' = ' = ' name1 ', ' age ' = ' age1 '), ' 1 ' =>array (' name ' = = ' name2 ', ' age ' = ') Age2 '), ' 2 ' =>array (' name ' = ' name3 ', ' age ' = ' age3 '));
for ($i =0; $i <2; $i + +) {
    Echo Deep_child ($ar [$i]);
     
}
function Deep_child ($ar = Array (), $i =0) {
    $str = ";
    static $i = 0;
     
    if (Isset ($ar [$i])) {
        $str. = '. Php_eol;
        $str. =  $ar [$i] [' name ']. " -". $ar [$i] [' age ']. Php_eol;
        $i + +;
        $str. =deep_child ($ar, $i);
         
        $str. = '. Php_eol;
     
    }
    return $str;
}
