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:
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;
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.
substr() function doesn’t mutate the original string, instead of it creates a new string with the modified data.
