The wordwrap() function is a built-in function in PHP. This function wraps a given string to a given number of characters using a string break character.
Syntax:
string wordwrap ($str, $width, $break, $cut )
Parameters : The function accepts 4 parameters as shown in the above syntax and are described below:
- $str: This parameter specifies the input string which is needed to break up into lines.
- $width: This parameter specifies the number of characters at which the string will be wrapped. That is number of characters after which the string will break.
- $break: This is an optional parameter and if specified appends the value at the point of breaking the string.
- $cut: It is a boolean parameter, if this parameter is set to TRUE, then the string is always wrapped at or before the specified width. That is it will also break a word from between if it comes in middle of the constraint specified by the parameter $width. When this parameter is set to FALSE the function does not split the word even if the width is smaller than the word width.
Return Value: The function returns a string wrapped upto specified length i.e. the string broken into lines on success, or FALSE on failure.
Below programs illustrate the wordwrap() function in PHP :
Program 1 :
<?php   // Input string $str = "keep practicing at neveropen";   // prints the wrapped string echo wordwrap($str, 15, "\n", TRUE);   ?> |
Output:
keep practicing at neveropen
Program 2 :
<?php   // Input String $text = "Be a part of neveropen.";   // Wrapped string $newtext = wordwrap($text, 8, "\n", TRUE);   echo "$newtext\n";   ?> |
Output:
Be a part of neveropenfor neveropen.
