200. PHP Program to find total number of characters in a string.
How does this program work?
- This program is used to find a character and replace with another character using PHP.
- Define and initialize a variable count to 0.
- Iterate through the string till the end and for each character except spaces, increment the count by 1.
- To avoid counting the spaces check the condition i.e. string[i] != ' '.
Here is the code

//Counts each character except space
for($i = 0; $i < strlen($string); $i++)
{
if($string[$i] != ' ')
$count++;
}
echo "Given String : ".$string."<br>";
//Displays the total number of characters present in the given string
