highlight_words ( array $word, string $subject )
Parameters
word
The words to highlight, this must be an array.
subject
The text which contain the word that should be highlighted
Return Values
This function will return the $word highlighted in the $subject
Example 1
Code
<?php
$words = array (
0 => "lemon",
1 => "banana"
);
$subject = "banana, apple, orange and lemon";
echo highlight_words($words, $subject);
?>Here you see the words to highlight already in an array given by the variable $words.
Output to Example 1
Quote
<span style='background-color:yellow;font-weight:bold;padding-left:2px;padding-right:2px'>banana</span>, apple, orange and <span style='background-color:yellow;font-weight:bold;padding-left:2px;padding-right:2px'>lemon</span>
Example 2
Code
<?php
$word = "lemon banana";
$words = explode(" ", $word);
$subject = "banana, apple, orange and lemon";
echo highlight_words($word1, $subject);
?>
We can't search for the $word as it is not an array, we therefore need to break it up and best way to do that is using the explode() function and store the result in the $words variable.
Output to Example 2
Quote
<span style='background-color:yellow;font-weight:bold;padding-left:2px;padding-right:2px'>banana</span>, apple, orange and <span style='background-color:yellow;font-weight:bold;padding-left:2px;padding-right:2px'>lemon</span>
Changelog
7.01.00 - New and optimised way to highlight words
Notes
The $word parameter must be an array!
