Have an $x as array:
$x1 = array(
0=>array("up1", -10, 1, 1, 2.5),
19=>array("up2",-4, 1.2, 2, 0.5)
);
I want to transform $x1 Became x2 like this:
$x2 = Array(
'A'=>
array(
"up1"=>array(-10, 1, 1, 2.5),
"up2"=>array(-4, 1.2, 2, 0.5)
)
);
Anybody can told help me algorithm to do this:?
$x2 = array();
foreach ($x1 as $x) {
$key = array_shift($x);
$x2['A'][$key] = $x;
}
Or, if you want to be really clever:
$x2 = array();
foreach ($x1 as $x) {
$x2['A'][array_shift($x)] = $x;
}
$x2 = array();
$i = 0;
foreach ( $x1 as $data ) {
if ( empty($x2['A']) ) {
$x2['A'] = array();
}
$x2['A'][ array_shift($data) ] = $data;
}
please try this out
for ( $i = 0 ; $x1[$i] != NULL ; $i++ ) {
$x1[$i] = 'a'=>($x1[$i]);
for ( $j = 0 ; $x1[$i][$j] != NULL; $j++ ) {
$x1[$i][$j] = 'up'.$j=> $x1[$i][$j];
}
}
for loops, don't make the condition $x1[$i] != NULL, it throws notices! Also, you have syntax errors with weirdly placed =>s.Here's how I would go about it. Not the best way but, it works fine.
$x1 = array(
0=>array("up1", -10, 1, 1, 2.5),
19=>array("up2",-4, 1.2, 2, 0.5)
);
$x2 = array( 'A' => array() );
foreach($x1 as $current) {
$key = $current[0];
unset($current[0]);
$x2['A'][$key] = $current;
}
