strchr() is just an alias for strstr()

Example 1: Basic Usage

Find the first occurrence of "world" in the string.

$text = "Hello world, the world is great!";
$result = strchr($text, "world");
echo $result;

world, the world is great!

Example 2: Using the before_needle Parameter

Return part of the string before the first occurrence of "world".

$text = "Hello world, the world is great!";
$result = strchr($text, "world", true);
echo $result;

Output

Hello

Example 3: Case-Sensitive Search

Searching for "World" will not match "world" due to case sensitivity.

$text = "Hello world, the world is great!";
$result = strchr($text, "World");
echo $result ? 'True':'False';

Output

False
