The Java String substring function is used to extract a portion of a string. It takes two parameters: the starting index and the ending index of the substring. The starting index is inclusive, meaning the character at that index is included in the substring, while the ending index is exclusive, meaning the character at that index is not included in the substring. If only the starting index is provided, the substring will include all characters from that index to the end of the string. The substring function returns a new string that contains the extracted portion of the original string. Keep reading below to learn how to Java String substring in PHP.

Java String substring in PHP With Example Code
Java String substring is a useful method that allows you to extract a portion of a string. If you’re working with PHP, you might be wondering how to achieve the same functionality. Fortunately, PHP has a similar function that you can use.
The PHP function for substring is called “substr”. It works in a similar way to the Java String substring method. You provide the starting index and the length of the substring you want to extract.
Here’s an example of how to use the substr function in PHP:
$string = "Hello, world!";
$substring = substr($string, 0, 5);
echo $substring; // Output: "Hello"
In this example, we’re extracting the first five characters of the string “Hello, world!”. The substr function takes two arguments: the string to extract from, and the starting index and length of the substring.
If you want to extract a substring from the end of a string, you can use a negative starting index. For example:
$string = "Hello, world!";
$substring = substr($string, -6);
echo $substring; // Output: "world!"
In this example, we’re extracting the last six characters of the string “Hello, world!”. The starting index is negative, which means we’re counting from the end of the string.
Overall, the substr function in PHP is a useful tool for extracting substrings from strings. It works in a similar way to the Java String substring method, so if you’re familiar with that, you should have no trouble using substr in PHP.
Equivalent of Java String substring in PHP
In conclusion, the equivalent function of Java’s String substring in PHP is the substr() function. This function allows developers to extract a portion of a string based on the starting index and the length of the substring. It is a powerful tool that can be used in various scenarios, such as manipulating strings, parsing data, and formatting output. By understanding the substr() function and its parameters, developers can efficiently work with strings in PHP and create robust applications. Overall, the substr() function is a valuable addition to any PHP developer’s toolkit.
