Finding a phrase

[papaface]

Hello,
I was wondering if someone can show me how (or point me in the right direction) I would:

[code]$file = file_get_contents("someurl.com")or die ("error " . mysql_error());
echo $file;[/code]

^^ use that code, and then ask php to find a particular phrase in the contents of the url, for instance: "Item price: $21" and then echo it out to the browser.
Note: the value of item total would change quite frequently, so i need a way of getting "Item price: something".

Thanks.

Anyone please?

Untested:
[code]<?php
preg_match_all("~^Item price: \$[0-9]~", $file,$out, PREG_PATTERN_ORDER);
foreach($out as $value){
    echo $value.'<br>';
}
?>[/code]

Thanks, but I get "Array" when using:
[code]<?php

$file = file_get_contents("someurl.com")or die ("error " . mysql_error());
echo $file;
preg_match_all("~^Item Price: \$[0-9]~", $file,$out, PREG_PATTERN_ORDER);
foreach($out as $value){
    echo $value.'<br>';
}[/code]

Try this:
[code]<?php

$file = file_get_contents("someurl.com")or die ("error " . mysql_error());
echo $file;
preg_match_all("~^Item Price: \$[0-9]~", $file,$out, PREG_PATTERN_ORDER);
foreach($out[1] as $value){
    echo $value.'<br>';
}
[/code]

I get:
Warning: Invalid argument supplied for foreach() in xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx on line 6

Try this, and if it doesn't work, than can you show the code that is in the file your retrieving?
[CODE]<?php

$file = file_get_contents("someurl.com")or die ("error " . mysql_error());
echo $file;
preg_match_all("~^[a-zA-Z]: \$[0-9]$/i~", $file,$out, PREG_PATTERN_ORDER);
foreach($out[0] as $value){
    echo $value.'<br>';
}[/CODE]

[code]<?php

$file = file_get_contents("http://www.amazon.co.uk/Sony-Ericsson-W800i-Vodafone-Weekends/dp/B000BSRU6I")or die ("error " . mysql_error());
echo $file;
preg_match_all("~^Price: \£[0-9]$/i~", $file,$out, PREG_PATTERN_ORDER);
foreach($out[0] as $value){
    echo $value.'<br>';
}
?>
[/code]
That is what im using. Its not the URL im really trying to use, but it still doesnt work.

I almost have it. Sorry for the wait.

[papaface]

No problem :)

I am so close, I am able to have it get this:
Price: £159: 9

But I need to get this:
Price: £159.99

[papaface]

Great :)

[The Little Guy]

This is the best I could come up with:
[code]<?php
$url = "http://www.amazon.co.uk/Sony-Ericsson-W800i-Vodafone-Weekends/dp/B000BSRU6I";
$html = file_get_contents(trim($url));
$match = explode("<b>",$html);
echo $match[1];
?> [/code]

Its good for that website. But as I mentioned the link I gave you isnt the link I want to use. The link I want to use is for something completely different. I basically need the ability to enter a phrase and for php to bring back the phrase then the number to the right of it, whether it be a currency or just a number. Do you have any other method of contact besides the forum The Little Guy ?
