Regular expressions - accents

[quimkaos]

I'm trying to verify if a string has only letters but i also want them with accents (eg: à, á, â and ã) and spaces. im using this:

eregi ("^([:alpha: ]+)$", $foo)

this will fail with the "special" chars i want. any suggestions? can any1 help please?

<pre>
<?php
echo $a_s = 'a à á â ã';
echo '<br>';
preg_match_all('/\p{L}/', $a_s, $matches);
print_r($matches);
?>
</pre>

it's not working since i want to use eregi that gives me a boolean type unser.

what i'm doing:

 

$fooo = "áà êaaa âotre";
if (!eregi ('/\p{L}/', $foo)){  //ask if $foo uses those chars. a-zA-Z (eregi is case insensitive anyway) and accents like à é ã. simply not numbers
$erro ++; // adds +1 to an variable (error)
$foo ="<font color='red'>".$foo." - formato do nome é inválido, por favor use um nome válido!</font>"; // makes foo display it's error
echo ($nome."</br>"); //...
}

Is there any reason you need to use eregi? The preg_* functions are often faster, and you can supply an "i" modifier to make them case insensitive.

 

If you insist on ereg, I think the only way you can achieve this is by changing your locale. See setlocale.
