I have a php array output like this
Array (
[DISEASE] => Array ( [0] => DM [1] => HT )
[DRUG] => Array ( [0] => INSULIN [1] => DIURETIC)
)
Now I want to print the following
For Disease DM, INSULIN is used
For Disease HT, DIURETIC is used
i.e I want to match the value from array Disease with that of Drug. Please help me.
Why don't you use the keys in an array? http://php.net/manual/en/language.types.array.php (see example one)
Then the array would look like:
$items = array(
array('disease' => 'DM', 'drug' => 'INSULIN'),
array('disease' => 'HT', 'drug' => 'DIURETIC'),
);
And you could call it like:
foreach($items as $item)
{
echo $item['disease'] . ' - ' . $item['drug'];
}
array_combine in this case even, see my answerThe key of an array points to its value. So your keys are DISEASE and DRUG each with keys of 0 and 1. So - we are matching keys not values.
There are many ways to print arrays. It is difficult for me to assume the most flexible way of printing these values for the future, but here is one way:
foreach ($items['DISEASE'] as $id => $disease)
{
echo 'For Disease ' . $disease . ', ' . $items['DRUG'][$id] . ' is used'."\n";
}
The key $id was used to match between the Disease and Drug sub-arays.
Assuming both arrays have the same length, you could do something like this:
for ($i=0; $i < sizeof($yourarray['DISEASE']); ++$i) {
echo 'For Disease ', $yourarray['DISEASE'][$i], ', ';
echo $yourarray['DRUG'][$i], ' is used';
}
for ($i=0,$s =sizeof($yourarray['DISEASE']); $i < $s; ++$i) instead
The
[DISEASE] => Array ( [0] => DM [1] => HT )
contains your keys.
The
[DRUG] => Array ( [0] => INSULIN [1] => DIURETIC)
contains the according values.
Assuming your array would be named $array, you can just combine both:
$mapped = array_combine($array['DISEASE'], $array['DRUG']);
Then you can access each drug for disease via the key:
$mapped['DM']; # INSULIN
To print all, just iterate
foreach($array['DISEASE'] as $disease)
{
$drug = $mapped[$disease]
echo "For Disease $disease, $drug is used.\n";
}
Here is the trick: You may get the point and can solve your problem
$an = array(
'numbers'=>array(1,2,3,4,5),
'alphabates'=>array('a','b','c','d','e')
);
foreach($an['numbers'] as $key=>$value){
echo $value." => ".$an['alphabates'][$key]."<br>";
}
