php - Access array in array elements

0 comments
Message:


I have an array named 'users' in which I am storing some variables as you see below.I want to verify if the 'nume' (name) value already existing in this array is the same as the value introduced by a person in a search box. I've tried some methods but I haven't obtained the wanted result. I think it is something obvious I can't see at the moment.


EDIT : The image is the result of var_dump() of my code. I am using it for people to understand what I want to know.




My Answer:
To access the 'nume' value in each element of the 'users' array, you can loop through the array and compare the 'nume' value with the value introduced by the person in the search box. Here's an example code snippet to achieve this:

php
// Sample 'users' array
$users = array(
array('nume' => 'John', 'age' => 25),
array('nume' => 'Jane', 'age' => 30),
array('nume' => 'Alice', 'age' => 28)
);

// Value introduced by the person in the search box
$searchValue = 'Jane';

// Flag to indicate if the value exists in the array
$valueExists = false;

// Loop through the 'users' array
foreach ($users as $user) {
if ($user['nume'] == $searchValue) {
$valueExists = true;
break;
}
}

// Check if the value exists in the array
if ($valueExists) {
echo "Value exists in the array";
} else {
echo "Value does not exist in the array";
}


In this code snippet, we loop through each element of the 'users' array and compare the 'nume' value with the value introduced in the search box. If a match is found, we set the `$valueExists` flag to true and break out of the loop. Finally, we check the value of the flag to determine if the value exists in the array.

You can adapt this code to your specific array structure and search requirements.
