PHP: Accessing array variables
Can someone help me access this array please I'm having trouble with index开发者_如何学Ces.
array(10) {
[0]=>array(2) {
["t"]=>array(1) {
["tag"]=>string(3) "php"
}
[0]=>array(1) {
["NumOccurrances"]=>string(1) "2"
}
}
[1]=>array(2) {
["t"]=>array(1) {
["tag"]=>string(6) "Tomcat"
}
[0]=>array(1) {
["NumOccurrances"]=>string(1) "1"
}
}
}
I want to use it in a foreach loop displaying like "PHP x 2" but am having trouble with the indexes
Thanks

something like
foreach($array as $entity)
{
echo $entity['t']['tag'] . ' x ' . $entity[0]['NumOccurrances'];
}
Would work.
foreach ($array as $key => $value){
echo $value['t']['tag'] . " x " . $value[0]['NumOccurrances'];
}
Does this do?
foreach ($tags as $t) {
echo $t['t']['tag'].' x '.$t[0]['NumOccurrances'].'<br />';
}
The structure seems a bit weird. If this does not help, please provide the rest of array.
foreach( $a as $item ) {
echo $item['t']['tag'] . 'x' . $item[0]['NumOccurrances'] . '<br>';
}
I wouldn't use a foreach
loop here. foreach
creates a copy of the array and therefore is not as efficient as a for
loop. Since your first dimension is numerically indexed, I would do the following:
$count = count($array);
for ($i = 0; $i < $count; ++$i){
echo $array[$i]['t']['tag'] . " x " . $array[$i][0]['NumOccurrances'];
}
I agree with vassilis that the array structure is odd.
