Hallo allemaal, ik heb een vraagje.
<?php
$m_array[1] = array("name" => "Test1", "rank" => 1);
$m_array[2] = array("name" => "Test2", "rank" => 2);
$m_array[3] = array("name" => "Test3", "rank" => 3);
?>
<?php
$m_array [ 1 ] = array ( "name" => "Test1" , "rank" => 1 ) ; $m_array [ 2 ] = array ( "name" => "Test2" , "rank" => 2 ) ; $m_array [ 3 ] = array ( "name" => "Test3" , "rank" => 3 ) ; ?>

PHP gevorderde Sorteren zou je kunnen met while of een for loop.
<?php
$m_array[1] = array("name" => "Test1", "rank" => 1);
$m_array[2] = array("name" => "Test2", "rank" => 2);
$m_array[3] = array("name" => "Test3", "rank" => 3);
$m_array[4] = array("name" => "Test1", "rank" => 1);
$m_array[5] = array("name" => "Test2", "rank" => 2);
$m_array[6] = array("name" => "Test3", "rank" => 3);
$i = 1;
$max = size(m_array);
$rank = 0;
while ($i <= $max) {
if ($m_array[$i][rank] == 2) {
$rank++;
}
}
echo ('Er zijn '.$rank.' mensen met rank nummer 2.');
?>
<?php
$m_array [ 1 ] = array ( "name" => "Test1" , "rank" => 1 ) ; $m_array [ 2 ] = array ( "name" => "Test2" , "rank" => 2 ) ; $m_array [ 3 ] = array ( "name" => "Test3" , "rank" => 3 ) ; $m_array [ 4 ] = array ( "name" => "Test1" , "rank" => 1 ) ; $m_array [ 5 ] = array ( "name" => "Test2" , "rank" => 2 ) ; $m_array [ 6 ] = array ( "name" => "Test3" , "rank" => 3 ) ; $i = 1 ;
$max = size( m_array) ;
$rank = 0 ;
while ( $i <= $max ) {
if ( $m_array [ $i ] [ rank] == 2 ) {
$rank ++;
}
}
echo ( 'Er zijn ' . $rank . ' mensen met rank nummer 2.' ) ; ?>

PHP gevorderde Mensen met alleen 2 kan je er makkelijk dan uit halen uit mijn script.
<?php
$m_array[1] = array("name" => "Test1", "rank" => 1);
$m_array[2] = array("name" => "Test2", "rank" => 2);
$m_array[3] = array("name" => "Test3", "rank" => 3);
$m_array[4] = array("name" => "Test4", "rank" => 1);
$m_array[5] = array("name" => "Test5", "rank" => 2);
$m_array[6] = array("name" => "Test6", "rank" => 3);
$i = 1;
$max = size(m_array);
echo ('Dit zijn de mensen met nummer 2: ');
while ($i <= $max) {
if ($m_array[$i][rank] == 2) {
echo (m_array[$i][name]);
}
}
?>
<?php
$m_array [ 1 ] = array ( "name" => "Test1" , "rank" => 1 ) ; $m_array [ 2 ] = array ( "name" => "Test2" , "rank" => 2 ) ; $m_array [ 3 ] = array ( "name" => "Test3" , "rank" => 3 ) ; $m_array [ 4 ] = array ( "name" => "Test4" , "rank" => 1 ) ; $m_array [ 5 ] = array ( "name" => "Test5" , "rank" => 2 ) ; $m_array [ 6 ] = array ( "name" => "Test6" , "rank" => 3 ) ; $i = 1 ;
$max = size( m_array) ;
echo ( 'Dit zijn de mensen met nummer 2: ' ) ; while ( $i <= $max ) {
if ( $m_array [ $i ] [ rank] == 2 ) {
echo ( m_array
[ $i ] [ name
] ) ; }
}
?>
<?php
$m_array[1] = array("name" => "Test1", "rank" => 1);
$m_array[2] = array("name" => "Test2", "rank" => 2);
$m_array[3] = array("name" => "Test3", "rank" => 3);
$m_array[4] = array("name" => "Test4", "rank" => 1);
$m_array[5] = array("name" => "Test5", "rank" => 2);
$m_array[6] = array("name" => "Test6", "rank" => 3);
$i = 1;
$d = 1;
$max = size(m_array);
while ($i <= $max) {
if ($m_array[$i][rank] == 2) {
$newarray[$d] = array("name" => m_array[$i][name]);
$d++;
}
}
?>
<?php
$m_array [ 1 ] = array ( "name" => "Test1" , "rank" => 1 ) ; $m_array [ 2 ] = array ( "name" => "Test2" , "rank" => 2 ) ; $m_array [ 3 ] = array ( "name" => "Test3" , "rank" => 3 ) ; $m_array [ 4 ] = array ( "name" => "Test4" , "rank" => 1 ) ; $m_array [ 5 ] = array ( "name" => "Test5" , "rank" => 2 ) ; $m_array [ 6 ] = array ( "name" => "Test6" , "rank" => 3 ) ; $i = 1 ;
$d = 1 ;
$max = size( m_array) ;
while ( $i <= $max ) {

keys die type string hebben altijd tussen quotes!

"Iedereen vergeet wel eens watÂ
en ik werk niet eens vaak met arrays." en dit noem je dus een bijdrage...?
En ik ga ook alle topics na. Als ik een onnodige reply vind, dan zeg ik er iets van (wat hier dus het geval is).
Dat ik iets over jou reply zeg, betekent toch niet meteen dat ik alleen jou in de gaten hou ?
Andere opmerkingen kun je gerust pmen, dan houden we dit topic schoon van dit soort onnodige discussies.
