How to Get the Last Char of a String in PHP

How to get the last char of a string in PHP?

substr("testers", -1); // returns "s"

Or, for multibyte strings :

mb_substr("multibyte string…", -1); // returns "…"

How can I get the last 7 characters of a PHP 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.

How to get position of last character in a string?

In PHP, as in most languages with zero-based indexing, the index of the last character in a string will be one less than the length of the string (strlen($string) - 1).

Find last character of php string

You should look into regular expressions using something like preg_match()

An expression like this would match:

/([a-z])[^a-z]*$/i

It means:

• ([a-z]) Capture an a-z character (the i at the end makes it case-insensitive)
• [^a-z]*$ followed by 0 or more non a-z characters until the end of the string

See an example.

PHP: Get nth character from end of string

Just do this

  $rest = substr("abcdef", -3, 1); // returns 'd'

Last character of php string in php

for( $i = 0, $len = strlen( $string ); $i < $len; $i++ )
{
    $char = $string[ $i ];
    // do something with $char
}

... is one way to do it.

Another way, is simply using PHP function str_split() (which creates an array of the individual characters of the string (unless you pass it the second argument $split_length of a different length than the default)):

foreach( str_split( $string ) as $char )
{
    // do something with $char
}

... etc.

Edit:

As an addendum to your comments to your question; use fgetcsv() for parsing csv files.

What is the simplest of checking first and last character of a string in php

if($str[0] == 'a' && $str[strlen($str) - 1] == 'a') {
    //do whatever you wanted
}

Remove trailing delimiting character from a delimited string

Contrary to the question asked, rtrim() will remove any number of characters, listed in the second argument, from the end of the string. In case you expect just a single comma, the following code would do:

$newarraynama = rtrim($arraynama, ",");

But in my case I had 2 characters, a comma and a space, so I had to change to

$newarraynama = rtrim($arraynama, " ,");

and now it would remove all commas and spaces from the end of the string, returning a, b, c, d, e either from a, b, c, d, e,, a, b, c, d, e,,,, a, b, c, d, e, or a, b, c, d, e , ,, , ,

But in case there could be multiple commas but you need to remove only the last one, then rtrim() shouldn't be used at all - see other answers for the solution that directly answers the question.

However, rtrim() could be a good choice if you don't know whether the extra character could be present or not. Unlike substr-based solutions it will return a, b, c, d, e from a, b, c, d, e
