I just built a simple foreach loop to run through an array, but nothing is displaying. No php errors by the way.
Can someone tell me why this isn't working?
$test = array (
"1" => array(
"name"=>"something"
),
"2" => array(
"name"=>"something"
)
);
foreach ($test as $key => $arr) {
echo $arr[$key]["name"];
}
Just use $arr["name"] instead of $arr[$key]["name"].
I think you meant...
foreach ($test as $key => $arr) {
echo $test[$key]["name"];
}
Or, even more simply...
foreach ($test as $key => $arr) {
echo $arr["name"];
}
$arr is just a convenient way to refer to $test[$key]. See php.net/manual/en/control-structures.foreach.php
$arr instead. You have a few ways to do this, obviously.
foreach ($test as $key => $arr) {
echo $test[$key]["name"];
}
OR
foreach ($test as $key => $arr) {
echo $arr["name"];
}
Your array is written in a way that "1" and "2" are values and not keys.
what you need is:
$test = array (
array(
"name"=>"something"
),
array(
"name"=>"something"
)
);
also, you have a typo on your foreach. you need $test[$key] and not $arr[$key]
You should use the $key key in the array reference.
foreach ($test as $arr) {
echo $arr["name"];
}
You can address the field of the array like
foreach ($test as $key=>$arr) {
$test[$key][$name]
}
but doing so you do not use the direct reference to the inner arrays
Try this,
foreach ($test as $key => $arr) {
echo $arr["name"];
}
Use
echo $arr["name"];
or
echo $test[$key]["name"];
