Change currency in PHP!

[Anon]

Hi there,

I'm trying to replace..
$string = "the price is £50 for that";

with...
"the price is $70 for that";
(currency exchange @ 1.4 US)

I have been struggling with ereg_replace. What way could i use?
Any help, tips or urls you can shout at me would be great!

Thanks
Later

str_replace() sounds like a good start.

Yeah, the problem is, how to use it. I have got it replacing somethings but with the math within a replace function is screwing me up.

You can use preg (perl regex).
has /e modifier ( evaluatin)
<?php

$var = "the price is £50 for that";
$pattern = array ("/£/","/(\d+)/e");
$replacement = array ("$","\1*1.5");
echo preg_replace($pattern, $replacement, $var);
?>

A sorry, missed the calculation bit :-)

Close but no cigar,
this will replace all numbers in the string, and it won't handle fractions.
So it will fail at this:
"This package costs £10.43 and you receive 5 items per package"

that's true.
an improved version:

<?php

$var = "the price is £50.95 for that";
$pattern = array ("/£/","/£(\d+.?\d)/e");
$replacement = array ("\$£","\11.33");
echo preg_replace($pattern,
$replacement,
$var);
?>

btw: in this case I wouldn't use regex
are slowly than split + x*y...
