PHP provides various array functions to access and manipulate the elements of the array. The important PHP array functions are given below.<\/p>\n\n\n\n

array() function<\/strong><\/p>\n\n\n\n

PHP array() function creates and returns an array. It allows you to create indexed, associative and multidimensional arrays.<\/p>\n\n\n\n

Syntax<\/p>\n\n\n\n

array array ([ mixed $… ] )<\/p>\n\n\n\n

Example<\/p>\n\n\n\n

<?php    <\/p>\n\n\n\n

$season=array(“summer”,”winter”,”spring”,”autumn”);    <\/p>\n\n\n\n

echo “Season are: $season[0], $season[1], $season[2] and $season[3]”;    <\/p>\n\n\n\n

?>    <\/p>\n\n\n\n

Output:<\/strong><\/p>\n\n\n\n

Season are: summer, winter, spring and autumn<\/p>\n\n\n\n

array_change_key_case() function<\/strong><\/p>\n\n\n\n

The PHP array_change_key_case() function changes the case of all keys of an array.<\/p>\n\n\n\n

Syntax<\/p>\n\n\n\n

array array_change_key_case ( array $array [, int $case = CASE_LOWER ] )  <\/p>\n\n\n\n

Example<\/p>\n\n\n\n

<?php    <\/p>\n\n\n\n

$salary=array(“Sonoo”=>”550000″,”Vimal”=>”250000″,”Ratan”=>”200000”);    <\/p>\n\n\n\n

print_r(array_change_key_case($salary,CASE_UPPER));   <\/p>\n\n\n\n

?>    <\/p>\n\n\n\n

Output:<\/p>\n\n\n\n

Array ( [SONOO] => 550000 [VIMAL] => 250000 [RATAN] => 200000 )<\/p>\n\n\n\n
