I know the function co开发者_如何学JAVAunt()
of php,
but what's the function for counting how often a value appear in an array?
Example:
$array = array(
[0] => 'Test',
[1] => 'Tutorial',
[2] => 'Video',
[3] => 'Test',
[4] => 'Test'
);
Now I want to count how often "Test" appears.
PHP has a function called array_count_values
for that.
Example:
<?php
$array = array(1, "hello", 1, "world", "hello");
print_r(array_count_values($array));
?>
Output:
Array
(
[1] => 2
[hello] => 2
[world] => 1
)
Try the function array_count_values
you can find more information about the function in the documentation here: http://www.php.net/manual/en/function.array-count-values.php
Example from that page:
<?php
$array = array(1, "hello", 1, "world", "hello");
print_r(array_count_values($array));
?>
Will produce:
Array
(
[1] => 2
[hello] => 2
[world] => 1
)
