PHP function in_array
This function checks a value within an array. If the value exists in the array, it returns TRUE else returns FALSE.
Syntax in_array
- value: value to search within the array
- array: Array input
- strict (optional): when set to TRUE the functions check string and numeric differently (i.e '30' != 30)
in_array(value, array, strict);
Example 1
<?php
$name = array('Ella', 'Amelia', 'Liam', 'Melanie');
if(in_array('Ella',$name)){
echo 'Ella <br/>';
}
else {
echo 'No Ella <br/>';
}
?>
Output
Ella
Example 2: Set the strict to TRUE
<?php
$name = array('30', 'Ella', 'Amelia', 'Liam', 'Melanie');
if (in_array(30, $name, 1)) {
echo '30 number Exist <br/>';
} else {
echo 'No Ella <br/>';
}
?>
Output
No Ella
Example 3
<?php
$name = array('30', 'Ella', 'Amelia', 'Liam', 'Melanie');
if (in_array(30, $name)) {
echo '30 number Exist <br/>';
} else {
echo 'No Ella <br/>';
}
?>
Output
