Strchr()

Our article is about the PHP function strchr(), which is used to find the first occurrence of a character in a string. In this article, we will discuss the syntax and usage of strchr(), as well as provide some examples.

The strchr() function is used to find the first occurrence of a character in a string. The syntax of the strchr() function is as follows:

strchr($string, $char, $before_searched_char)

The function takes three parameters: $string, $char, and $before_searched_char (optional).

$string is the string to be searched, $char is the character to search for, and $before_searched_char is an optional boolean parameter that specifies whether to return the part of the string before the first occurrence of $char.

Here is an example of how to use the strchr() function:

<?php
$string = "Hello World";
$char = "o";
$result = strchr($string, $char);
echo $result;
?>

In this example, we have a string variable $string and a character variable $char. The strchr() function is used to find the first occurrence of $char in $string. The result is stored in the variable $result, which is then printed to the screen.

The output of this code will be:

o World

As you can see, the strchr() function has successfully found the first occurrence of the character "o" in the string "Hello World" and returned the remaining part of the string starting from that character.

The strchr() function is a useful tool for finding the first occurrence of a character in a string in PHP. It can be used to perform operations that depend on the position of a character in a string, such as substring extraction, string manipulation, and more. By mastering this function, you can become a more proficient PHP developer.
