I am making a web application, I am trying to use a foreach loop and I have run into some problems.
Example
$arr = array(
'username' => 'Test',
'password' => 'Cheese',
);
foreach($arr as $arr2){
echo $arr2['username'];
}
That will output this:
Warning: Illegal string offset 'username' in PATH on line 8 T
Warning: Illegal string offset 'username' in PATH on line 8 C
Does anyone know how to fix this issue.
The array you have described does not really warrant a foreach loop. You can simply do:
echo $arr['username'];
If your intention is to loop through all the different bits of data, then you can do this:
foreach ($arr as $key => $value) {
echo $key . ': ' . $value . '<BR>';
}
Which will output something like:
username: Test
password: Cheese
More info on PHP's manual page for arrays
<?php
$arr = array(
'username' => 'Test',
'password' => 'Cheese',
);
echo $arr['username'];
echo $arr['password'];
?>
does not require foreach
