find the index of an element in an array in php

To find the index of an element in an array in PHP, you can use the array_search() function. It returns the index of the first occurrence of the searched element in the array or returns false if the element is not found. Here's an example code:

main.php
$fruits = array('apple', 'banana', 'orange', 'grape');
$index = array_search('orange', $fruits);
if ($index !== false) {
    echo "The index of 'orange' is " . $index;
} else {
    echo "Element not found";
}

8 lines

The above code will output the index of the element 'orange' in the array which is 2.

Alternatively, you can also use a loop to search for the element and return the index:

main.php
$fruits = array('apple', 'banana', 'orange', 'grape');
$search = 'orange';
foreach ($fruits as $index => $value) {
    if ($value == $search) {
        echo "The index of '$value' is " . $index;
        break;
    }
}

This code will output the same result as the previous one. The break statement is used to exit the loop once the element is found to avoid unnecessary iterations.
