Mastering PHP hebrevc() Function: Step-by-Step Guide with Example & Best Practices

When dealing with Hebrew text that includes newline characters, formatting can be tricky. The PHP hebrevc() function makes it easy to convert logical Hebrew text with newlines into visually correct HTML by reversing characters and converting \n into <br> tags.

This guide covers everything you need to know about hebrevc() with hands-on examples and tips to write clean, effective PHP code.

๐Ÿ“Œ What is hebrevc() in PHP?

The hebrevc() function in PHP is used to:

  • Reverse logical Hebrew text to visual text

  • Replace newline characters (\n) with HTML line breaks (<br>)

This function is particularly useful when rendering Hebrew text in web applications where newlines should appear as line breaks in HTML.

โœ… Syntax

hebrevc(string $hebrew_text, int $max_chars_per_line = 0): string

Parameters:

  • $hebrew_text โ€“ Required. The logical Hebrew text you want to reverse and format.

  • $max_chars_per_line โ€“ Optional. Maximum number of characters per line (default is 0, which means no limit).

๐Ÿง  How hebrevc() Works: Step-by-Step

Step 1: Understand the Input

You have a Hebrew string with newline characters (\n), and you want it:

  • Displayed visually from right to left

  • With each newline represented as <br>

Step 2: Apply hebrevc()

Use the function directly in your PHP code.

Step 3: Echo or return the result to your HTML template.

๐Ÿ’ป Example: Using hebrevc() in Real Code

<?php
$logical_hebrew = "ืฉืœื•ื ืขื•ืœื\nื–ื•ื”ื™ ืฉื•ืจื” ืฉื ื™ื™ื”";
$formatted_output = hebrevc($logical_hebrew);

echo $formatted_output;
?>

๐Ÿ” Output:

ย 
ืืœื•ืข ืื•ืœืฉ<br>ื”ื™ื™ื ืฉ ื”ืจื•ืฉ ื™ื•ื”ื–

โœ”๏ธ The function:

  • Reversed the Hebrew words for proper visual display.

  • Converted the \n into <br> for HTML line breaks.

๐Ÿ’ก Best Practices for hebrevc()

  • Use only for Hebrew text.
    This function is specifically designed for Hebrew; avoid using it with non-Hebrew content.

  • Combine with htmlspecialchars()
    To ensure special characters like < or & don’t break your layout:

    ย 
    echo hebrevc(htmlspecialchars($hebrew_text));

  • Avoid styling issues
    Wrap Hebrew content in a container with dir="rtl" (right to left):

    <div dir="rtl"> <?php echo hebrevc($hebrew_text); ?> </div>

  • Do not double-escape
    Donโ€™t use nl2br() after hebrevc()โ€”it already does that.
