Start with this current pattern. The examples below are retained, corrected where necessary, and expanded for additional variations and output.

echo str_pad("plus2net.com",15,"*",STR_PAD_LEFT);//output:   ***plus2net.com
echo str_pad("plus2net.com",15,"*",STR_PAD_BOTH);//output:  *plus2net.com**

Using the string function str_pad() we can pad one input string upto some given length or pad using another string. If no second string is given then the input string is padded by blank space.

This function is useful when some data is to be formatted upto some length. We want the blank space after the input or marked with some chars like ---- . Another example is where we are displaying data in rows and wants all records to perfectly align in left and right. Here if all data are not of equal length we can pad them and keep all in one line. The extra space can be formatted as per requirement.
