[SOLVED] bolding array values

[asmith]

hey guys

 

I have an array of values and I want to bold all values in the $content. each time this array changes, can contain 20 values, or sometime 0 . 

 

how do i write this with preg_replace?

Now, do you only wants it to be replaced when it's actually its own word, or does it not matter where in a word it is?

 

I.E:

$content = array('test');

$string = "We have a new contestant!";

//replace stuff

echo $string;

 

And it echos: We have a new con<b>test</b>ant!  Is that what you want?

[asmith]

yes, thanks

 

array("test","mountain","php");

<b>test<b>,<b>mountain</b>,<b>php</b>

 

the array is a variable that can have changeable number of values. but your pattern is what i want.

I realize that you posted this in regex, but if you just want to bold each element in the array you could:

 

<?php
$testarray = array('this', 'will', 'be', 'bolded');
$boldarray = array_map('boldarray', $testarray);

function boldarray($el){
    return '<b>' . $el . '</b>';
}
print_r($boldarray);

$words = array("test","mountain","php");
$string = 'this is a test string, about a php mountain';

echo preg_replace('~\b('.implode('|', $words).'[a-zA-Z]{0,3}[0-9]{0,3})\b(?![^<]*[>])~is','<strong>$0</strong>',$string);

Thanks little guy

 

just one thing.  your code does not fint the words  this  :

 

$string = 'this is a test string, about a thephp mountains';

 

 

When they are sticked after or before or in a word. (I made those letter italic)

How about this:

 

$words = array("test","mountain","php");
$string = 'this is a test string, about a thephp mountain';

echo preg_replace('~('.implode('|', $words).')~','<strong>$0</strong>',$string);
