.substr
function with substr($str, 0, 5)
to get the first 5 characters.$str = "Hello World";
$first5Chars = substr($str, 0, 5);
print "First 5 characters of the string are: $first5Chars\n";
First 5 characters of the string are: Hello
In this example,
$str
with a string value of "apple"
.substr
function with substr($str, 0, 3)
to get the first 3 characters.$str = "apple";
$first3Chars = substr($str, 0, 3);
print "First 3 characters of the string are: $first3Chars\n";
