Basic usage of hebrev function: Convert Hebrew text to reverse format

gitbox 2025-05-29

What is the hebrev() function?

The function of the hebrev() function is to reverse the order of the given Hebrew string from left to right to right. Simply put, it is to reverse the text so that it can still be displayed correctly without supporting the RTL (Right To Left) text environment.

The syntax is as follows:

 string hebrev ( string $text [, int $max_chars_per_line = 0 ] )

$text : Hebrew text that needs to be converted.
$max_chars_per_line (optional): Sets the maximum number of characters per line. If the number of characters exceeds, the line will be wrapped automatically.

Sample code

Suppose you have a Hebrew text:

 <?php
$hebrewText = "???? ????"; // Meaning“Hello，world”

// use hebrev Functions are converted
$reversedText = hebrev($hebrewText);

echo $reversedText;
?>

The output result will be:

 ???? ????

In this way, the Hebrew is correctly displayed from right to left.

More practical usage: combined with line break function

If your Hebrew text is long, you can automatically wrap the line by setting the $max_chars_per_line parameter to avoid the long line when displayed:

 <?php
$hebrewText = "??? ???? ?????? ????? ????? ???? ????? ????? ????? ?????";

$converted = hebrev($hebrewText, 10);

echo nl2br($converted);
?>

This code breaks the text line every 10 characters and maintains the reverse display format of Hebrew.

Things to note

The hebrev() function is only suitable for Hebrew text, and may cause partial display exceptions if the text is mixed with English or numbers.
For modern web development, it is recommended to use CSS's direction: rtl; attribute combined with HTML tags to control text orientation, which is more flexible and standardized.
But if you need to quickly implement text reverse processing in a pure PHP environment, hebrev() is a very convenient tool.
