At first I planned to use foreach to iterate through it, but found that it was not successful, oo failed, and there was no way to write oo...
After research, I decided to use a for loop. The demonstration code is as follows:

Copy the code The code is as follows:


$blog=array(
array(
"titledata"=>"titleMM",
"bodydata"=>"bodyMM"
),
array(
"titledata"=> "titleGG",
"bodydata"=>"bodyGG"
)
);
//Error
foreach($blog as $b)
{
$b['titledata']="BB";
$b ['bodydata']="CC";
}
print_r($blog);
//Correct
for($i=0;$i{
$blog[$ i]['titledata']="title";
$blog[$i]['bodydata']="body";
}
?>

The above has introduced the array PHP code for traversing a two-dimensional array, including array content. I hope it will be helpful to friends who are interested in PHP tutorials.
