Note: If the search parameter is a string and the type parameter is set to TRUE, the search is case-sensitive.
Syntax :
in_array(search,array,type)
search - Required. Specifies the what to search for
array - Required. Specifies the array to search
type - Optional. If this parameter is set to TRUE, the in_array() function searches for the search-string and specific type in the array.
Return Value - Returns TRUE if the value is found in the array, or FALSE otherwise.
Example :
<?php
$people =
array("Peter", "Joe", "Glenn",
"Cleveland", 23);
if (in_array("23",
$people, TRUE))
{
echo "Match
found<br>";
}
else
{
echo "Match not found<br>";
}
if
(in_array("Glenn",$people, TRUE))
{
echo "Match
found<br>";
}
else
{
echo "Match not found<br>";
}
if (in_array(23,$people, TRUE))
{
echo "Match found<br>";
}
else
{
echo "Match not found<br>";
}
?>
