Preg_Match Alternative

Right now I am using preg_match to give me this kind of results:


"I want to store go" Where I preg_match "store go" to echo "I want to go to the store"

What I want though, is to preg_match inside a sentence and replace only a part of that sentence, the part that was matched, while leaving the rest the same. So I could have this sentence:

"I want to 'store go' this afternoon"

Where I would preg_match "store go" and echo it with the replacement:

"I want to 'go to the store' this afternoon."

Another function would be ok too as long as I could do what I wanted.. javascript too.. Just looking for a way to do it.

 

you can use str_replace or preg_replace or ereg_replace to do what you are looking to do.

The easiest is going to be something like this:

$string = 'I want to store go';

$newString = str_replace('store go', 'go to the store', $string);

PHP:

http://www.php.net/str_replace
http://www.php.net/ereg_replace
http://www.php.net/preg_replace

 

Wonderful.. yes yes.. what I was looking for. Possible to do multiple replaces?

 

You can replace using an array of needles and haystacks.

$matchArray = array('store go', 'hi there', 'super market');
$replaceArray = array('go to the store' , 'hello', 'gas station');

$string = 'hi there, I store go super market';

$newString = str_replace($matchArray,$replaceArray,$string);
//will output 'hello, I go to the store gas station'

PHP:

 

Man.. Thank you very much. Have a great evening.. or day..

 

I'm sorry.. one more question if you are still here. Font color. Can I add a font color to the replaced text?

 

You could do something like:

$replaceArray = array(
'<span class="blue">go to the store</span>' , 
'<span style="color:#03f;">hello</span>', 
'gas station'
);

PHP:

I would use a span class and then specify in your stylesheet to change the color.

 

Rep given.. thanks for the input today.. exactly what I needed.

 

I would like to do this with a mysql database. I tried using a connection and replacing the hard coded results for $matcharray and $replaceArray with $row[rowname] but I am not getting it to loop through all possible. Any suggestions?

<?
$matchArray = array
(
'word 1',
'word 2'
);

$replaceArray = array
(
'<span style="color:#03f;">replacement 1</span>',
'<span style="color:#03f;">replacement 2</span>'
);

$string = $_POST['data'];
$newstring = str_replace($matchArray,$replaceArray,$string);
echo "<center><b>Old Text</center></b><br/><hr>";
echo $_POST['data'];
echo "<br/><br/>";
echo "<center><b>New Text</center></b><br/><hr>";
echo $newstring;
?>
