Print something only when the value is inside a specific group during a loop in PHP
I have a large array that is used throughout the site and only changes its structure for the next task - it's a pain. I want to make multiple boxes with a different array. The result I want to get looks like this:
/* Example Array:
$allAnimals = array("Frogs","Toads","Bats","Elephants","Rats","Seals",
"Crocodilians","Turtles");
$group = array("Frogs"=>"Amphibian","Bats"=>"Mammal","Crocodilians"=>"Reptile");
*/
<select name='Amphibian'>
<option value='0'>Frogs</option>
<option value='1'>Toads</option>
</select>
<select name='Mammal'>
<option value='2'>Bats</option>
<option value='3'>Elephants</option>
<option value='4'>Rats</option>
<option value='5'>Seals</option>
</select>
<select name='Reptile'>
<option value='6'>Crocodilians</option>
<option value='7'>Turtles</option>
</select>
I cannot figure out how to print the parameters only when the value is within a certain group of animals during each iteration $group
. I tried each()
to get the next animal $endAnimal
from $group
and then break the inner loop if it $animal
matches $endAnimal
, but I also need to make the loop start print parameters with specific values.
<?php
$allAnimals = array("Frogs","Toads","Bats","Elephants","Rats","Seals","Crocodilians","Turtles");
$group = array("Frogs"=>"Amphibian","Bats"=>"Mammal","Crocodilians"=>"Reptile");
foreach($group as $thisAnimal=>$category){
$nextKey = (each($group));
$endAnimal = $nextKey['key'];
print "<select name='$category'>";
foreach($allAnimals as $idx=>$animal){
print "<option value='$idx'>$animal</option>";
if($endAnimal === $animal){
break;
}
}
print "</select>";
}
?>

Please check it: -
<?php
$allAnimals = array("Frogs","Toads","Bats","Elephants","Rats","Seals","Crocodilians","Turtles");
$group = array("Frogs"=>"Amphibian","Bats"=>"Mammal","Crocodilians"=>"Reptile");
$group_keys = array_keys($group); // get the keys of group array
$j = 0;
foreach($group_keys as $key => $group_k){
print "<select name='$group[$group_k]'>";
if(isset($group_keys[$key+1])){
$new_value = $group_keys[$key+1];
}else{
$new_value = '';
}
if($new_value ==''){
foreach($allAnimals as $key => $allAnm){
print "<option value='$j'>$allAnm</option>";
unset($allAnimals[$key]);
$j ++;
}
}else{
$key_from = array_search($new_value,$allAnimals);
for($i = 0; $i<$key_from; $i++){
print "<option value='$j'>$allAnimals[$i]</option>";
unset($allAnimals[$i]);
$j ++;
}
}
$allAnimals = array_values($allAnimals);
print "</select>";
}

Array array is the solution I believe
$group = array( "Amphibian" => array("Frogs", "Toads"), "Mammal" => array("Bats", "Elephants", "Rats", "Seals"), "Reptile" => array("Crocodilians", "Turtles") );
foreach($group as $thisAnimal=>$category){
print "<select name='$category'>";
foreach($category as $idx=>$animal){
print "<option value='$idx'>$animal</option>";
}
print "</select>";
}

Thanks for your responses and responses. I just like to work, checking, whether $thisAnimal
from $group
the same as that $animal
of $allAnimals
in the inner loop. If it's the same, turn $passThis
in true
and then go to print the option until $endAnimal
it matches $animal
. Example
<?php
$allAnimals = array("Frogs","Toads","Bats","Elephants","Rats","Seals","Crocodilians","Turtles");
$group = array("Frogs"=>"Amphibian","Bats"=>"Mammal","Crocodilians"=>"Reptile");
foreach($group as $thisAnimal=>$category){
$nextKey = (each($group));
$passThis = false;
$endAnimal = $nextKey['key'];
print "<select name='$category'>";
foreach($allAnimals as $idx=>$animal){
if($animal === $thisAnimal){
$passThis = true;
}
if($endAnimal === $animal){
break;
}
if($passThis === true)
{
print "<option value='$idx'>$animal</option>";
}
}
print "</select>";
}
?>
