How would I go about grabbing the last 7 characters of the string below?
For example:
$dynamicstring = "2490slkj409slk5409els"; $newstring = some_function($dynamicstring); echo "The new string is: " . $newstring; Which would display:
The new string is: 5409els

The strlen() is a built-in function in PHP which returns the length of a given string. It takes a string as a parameter and returns its length. It calculates the length of the string including all the whitespaces and special characters.
To get substring having last 4 chars first check the length of string. If string length is greater than 4 then substring(int beginIndex) method. This method takes index position as method argument and return the complete string from that specified index.
To get the last N characters of a string, call the slice method on the string, passing in -n as a parameter, e.g. str. slice(-3) returns a new string containing the last 3 characters of the original string. Copied! const str = 'Hello World'; const last3 = str.
You can use the PHP substr_replace() function to remove the last character from a string in PHP. $string = "Hello TecAdmin!"; echo "Original string: " . $string .
Use substr() with a negative number for the 2nd argument.
$newstring = substr($dynamicstring, -7); From the php docs:
string substr ( string $string , int $start [, int $length ] )If start is negative, the returned string will start at the start'th character from the end of string.
