Introduction
This article explains how to justify a line of text in PHP. I will use some string functions for justifying a line of text. Justifying text means aligning text within a column so that the text is flush with both the left and right margins. Using this article you can justify a paragraph or line of text in a page. For example see the following.
Example
<html>
<head>
<title>Justifying Lines of Text </title>
</head>
<body>
<h1>Justifying Lines of Text </h1>
<?php
$txt = <<<END_TEXT
This article explains adding and
removing Array Elements in PHP.
For this explanation I used some
functions for adding and removing array
elements. These functions are very
important and useful to us in an array
adding a removing.
END_TEXT;
$txt = str_replace("\r\n", "\n", $txt);
$L_length = 40;
$txtJustify = "";
$nofline = substr_count( $txt, "\n" );
$strtofline = 0;
for ( $i=0; $i <$nofline; $i++ )
{
$originallength = strpos( $txt, "\n", $strtofline ) - $strtofline;
$justifyline = substr( $txt, $strtofline, $originallength );
$justifyL_length = $originallength;
while ( $i <$nofline - 1 && $justifyL_length <$L_length )
{
for ( $j=0; $j <$justifyL_length; $j++ )
{
if ( $justifyL_length <$L_length &&$justifyline[$j] == " " )
{
$justifyline = substr_replace( $justifyline, " ", $j, 0 );
$justifyL_length++;
$j++;
}
}
}
$txtJustify .= "$justifyline\n";
$strtofline += $originallength + 1;
}
?>
<h2>Original line of text: </h2>
<pre>
<?php
echo $txt;
?>
</pre>
<h2>Justified line of text: </h2>
<pre>
<?php
echo $txtJustify;
?>
</pre>
</body>
</html>
Output
The first block of text is unjustified text and the second block of text is justified text. Such as:
