Length of a string- PHP Program
In this example, we will take the inputs from the user and store them in variables.
<html>
<head><title>Reverse String</title></head>
<body>
<form method="post">
Enter String:
<input type="text" name="str"/>
<input type="submit" name="ok"/>
</form>
<?php
if(isset($_POST['ok'])){
$data = $_POST['str'];
echo" <h3>$data</h3> <br/>";
foreach (count_chars($data, 1) as $i => $val) {
echo "There were $val \"" , chr($i) , "\" in the string.<br/>";
}
}
?>

Length of a string PHP Program with form and database
In this example, we will take the inputs from the user and temporarily store them in variables and then finally stores them permanently in the database.
<html>
<head><title>Reverse String</title></head>
<body>
<form method="post">
Enter String:
<input type="text" name="str"/>
<input type="submit" name="ok"/>
</form>
<?php
if(isset($_POST['ok'])){
$data = $_POST['str'];
echo" <h3>$data</h3> <br/>";
$fr=0;
foreach (count_chars($data, 1) as $i => $val) {
$fr=$fr+$val;
echo "$fr There were $val \"" , chr($i) , "\" in the string.<br/>";
}
$conn = new mysqli("localhost", "root", "","test");
$sql = "INSERT INTO table1 (StringInput, Frequency) VALUES ('$data', '$fr')";
if ($conn->query($sql) === TRUE) {
echo "New record created successfully";
} else {
echo "Error: " . $sql . "<br>" . $conn->error;
}
}
?>
