How to check the value of an array with a variable?

Question

PHP

Hello.
There is an array $arr[2] and a variable $var = "Two";
It has the following data:
- $arr[0] = "One";
- $arr[1] = "Two";
- $arr[2] = "Three";
You need to check if at least one value of the array is equal to the variable.

Answer 1

To solve your problem, there is a function array_search , which searches through the values ​​of an array.

// вернет ключ в массиве, или false, если элемент не найден
array_search($var, $array);

To check for availability should be used like this:

if (array_search($var, $array) !== false) {
  // элемент существует 
} else {
  // элемент не найден
}

If you often have entry-level questions, it's best to go to some conference in jabber/irc/etc. For example, jabber-conference [email protected] I also recommend bookmarking the link to the official PHP documentation.
