Typically these elements are all of the same data type, such as an integer or string. php array are commonly used in computer programs to organize data so that a related set of values can be easily sorted or searched.

An array can hold many values under a single name, and you can access the values by referring to an index number.

Create an Array in PHP

 In PHP, the array() function is used to create an array

 

array();

In PHP, there are three types of arrays:

  • Indexed arrays - Arrays with a numeric index
  • Associative arrays - Arrays with named keys
  • Multidimensional arrays - Arrays containing one or more arrays
//Array declaration
$names = ['Websolutionstuff', 'Web', 'Solution', 'Stuff'];

 

 

//add to array
$names[] = 'Websolutionstuff';

 

Array merge :

// Array merge
$array3 = array_merge($array1, $array2);

 

Array to string :

// Array to string
$text = implode(', ', $names); // 'Websolutionstuff, Web, Solution'

 

String to Array :

// String to Array
echo explode(',', $text); // ['Websolutionstuff', 'Web', 'Solution']

 

Remove and preserve keys :

// Remove and preserve keys
unset($names[1]); 
// It is now => [0 => 'Websolutionstuff', 2 => 'Solution']

 

 

Remove and change keys :

// Or remove and change keys
array_splice($names, 1, 1);
// It is now => [0 => 'Websolutionstuff', 1 => 'Solution']

 

Number of items in a Array :

// Number of items in a Array
echo count($names);

 

Associative array :

//Associative array:
$person = ['age' => 25, 'gender' => 'men'];

 

Check if a specific key exist :

// Check if a specific key exist
echo array_key_exists('age', $person);

 

Array filter :

//Array filter (return a filtered array)
$filteredData = array_filter($people, function ($person) {
    return $person->active;
});

 

Search all value :

// search all value in the 'name' column
$found_key = array_search('men', array_column($gender, 'name'));
// return 2
