Hello Friends Today, through this tutorial, I will tell you How do You pad a string to a certain length using php the `str_pad()` function With Example? In PHP, you can pad a string to a certain length using the `str_pad()` function. This function allows you to add characters to the beginning or end of a string until it reaches the desired length. Here’s an example of how to use `str_pad()`:
<?php // Original string $string = "Hello"; // Pad the string to a length of 10 with spaces added to the right $padded_string = str_pad($string, 10); echo "Padded string: '$padded_string'"; // Output: "Padded string: 'Hello '" // Pad the string to a length of 10 with dashes added to the left $padded_string_left = str_pad($string, 10, "-", STR_PAD_LEFT); echo "Padded string (left): '$padded_string_left'"; // Output: "Padded string (left): '-----Hello'" // Pad the string to a length of 10 with dots added to the right $padded_string_right = str_pad($string, 10, ".", STR_PAD_RIGHT); echo "Padded string (right): '$padded_string_right'"; // Output: "Padded string (right): 'Hello.....'" ?>
In this example:
1. The original string is “Hello”.
2. `str_pad()` is used to pad the string to a length of 10 characters.
3. By default, spaces are added to the right if no padding character is specified.
4. You can specify a different padding character and also choose to pad to the left or right by providing the third argument. The fourth argument specifies the padding type, which can be `STR_PAD_LEFT`, `STR_PAD_RIGHT`, or `STR_PAD_BOTH`.
