Lets Start with this PHP check if a String is in multidimensional array step by step:

So Let’s with this, I have an array which contain the employees details with employeid,name ,amount.

These employees details are in the form called multidimensional-array. From this array, I have to find the specific value of employees. For this, I am going using to array function.

The array function i am going to use are as follow as:

- array_column()
- array_search()

So how we going to use this both array function to check string or value is contained in a multidimensional array. Suppose I want employeid for specific employe.

That is I want to check employee id is present in the array or not so I am going to use the first array_column. Array column what going to do is returns the values from a single column in the input array.

So for that, I have to pass the array key. After passing the array key it will return a single column.

Then I am going to use the array search function, using this I am going to get specific value or string check bypassing this string value if it is present in this multidimensional array, then it will return "Value Present in Array" or if it is not present then it will return "Value Not Found".

Below Is the example how we can achieve this.

<!doctype html>
<html lang="en">
<head>
  <meta charset="utf-8">
  <title>contains demo</title>
</head>
<body>
<?php
 
$search=Array
        (
        '0' => Array
           (
           'emp_id' => '100',
           'emp_name' => 'Peter',
           'emp_amount' => '900'
           ),
        '1' => Array
           (
           'emp_id' => '101',
           'emp_name' => 'John',
           'emp_amount' => '800'
           ),
        '2' => Array
           (
           'emp_id' => '106',
           'emp_name' => 'Jack',
           'emp_amount' => '500'
           )
        );
		
		if(array_search(100, array_column($search, 'emp_id')) !== False) {
			echo "Value Present in Array";
		} else {
			echo "Value Not Found";
		}
?>
</body>
</html>
