ereg_replace & file string

[Anon]

Hello,

I am having trouble searching for a regular expression in a file string.

i am trying to search for

define('TITLE','My Web Site');
and replace it with
define('TITLE','$title2');
where title2 is a form field

This line doesnt find the reg exp im looking for
ereg_replace("define('TITLE','[^{']');",$replacement,$file);}

<?php

$fle=fopen("catalog/includes/languages/english.php",r);
$file=fread($fle,5000000000);
$replacement="define('TITLE', $title2)";
$newfile=ereg_replace("define('TITLE','[^{']')",$replacement,$file);}
fclose($fle);
$fp=fopen("catalog/includes/languages/english.php",w);
if(fwrite($fp,$newfile,strlen($newfile))){
echo "good";
}
else{
echo "bad";
}
fclose($fp);

?>

Thanks in advance for your help.

You should escape ( and ) because they have a special meaning in regular expressions.

[^'] only matches one character. If you want to match more characters use [^']* or [^']+

ereg_replace("define('TITLE','[^{']+')",$replacement,$file);}

It's better to use preg_replace instead of ereg_replace because it is dramatically faster and has much more possibilities.

preg_replace("/define('TITLE','[^{']+')/",$replacement,$file);}

Warning: Delimiter must not be alphanumeric or backslash in /home/topwebho/public_html/set_title.php on line 5

It gives me that warning, for this code

<?php
$file=implode("",file("catalog/includes/languages/english.php"));
$replacement="define('TITLE','$title2')";
$newfile=preg_replace("define('TITLE','[^{']+')",$replacement,$file);}

$fp=fopen("catalog/includes/languages/english.php",w);
if(fwrite($fp,$newfile,strlen($newfile))){
echo "good";
}
else{
echo "bad";
}
fclose($fp);
?>

You forgot the regexp delimiters PCRE syntax uses:
-----------------------v-----------------------v
$newfile=preg_replace("/define('TITLE','.+?')/",$replacement,$file);

I also tweaked the regexp slightly.

Thanks,

The regexp seems to work but its not writing to the file
fwrite($fp,$newfile,strlen($newfile));

got any tips?

<?php

$file=implode("",file("catalog/includes/languages/english.php"));
$replacement="define('TITLE','$title2')";
$newfile=preg_replace("/define('TITLE','.+?')/",$replacement,$file);
$fp=fopen("catalog/includes/languages/english.php",w);
if(fwrite($fp,$newfile,strlen($newfile))){
echo "good";
}
else{
echo "bad";
}
fclose($fp);

?>
