Remove the First Character of a string in PHP
In this tutorial, we are going to learn about how to remove the first character of a string in PHP.
Consider, we have a following string:
$place="/paris";
Now, we want to remove the first character slash /
from the above string.
Note: In PHP, strings are the sequence of characters that can be accessed by using its character index, where the first character index is 0, second character is 1 and the first character index is -1, etc.
Removing the first character
To remove the first character of the string, we can use the built-in substr()
function by passing string , 1
as a arguments. It returns a new string by removing the first character.
The substr() function accepts three arguments, the first one is string
, the second is start position, third is length (optional).
Here is an example :
$place="/paris";
$result = substr($place, 1);
echo $result;
Output:
"paris"
In the example above, we have passed 1
as a second argument to the substr()
function. so it begins the extraction at index 1
, and extract the rest of a string.
Note: The substr()
function doesn’t mutate the original string, instead of it creates a new string with the modified data.
