PHP script mucks up copyright -

-

i have written php script goes through , changes html generated visual page. (i know - old program - it.) anyway, in each of these html web pages i'm working put in:

{copyright}

where want copyright show up. did following loop:

foreach( $file $k1=>$v1 ){    if( preg_match("/\{copyright\}/i", $v1) ){       $file[$k1] = preg_replace( "/\{copyright\}/i", $copyright, $v1 );       }    }

this did not work. echo out $file[$k1] before , after if statement see going on , php wouldn't change {copyright} copyright. variable $copyright had similar to:

<tr><td>copyright 2007-now mycompany.  rights reserved.</td></tr>

now - here freaky thing: put break after did preg_replace - , - worked. changing above to

foreach( $file $k1=>$v1 ){     if( preg_match("/\{copyright\}/i", $v1) ){         $file[$k1] = preg_replace( "/\{copyright\}/i", $copyright, $v1 );         break;         }     }

made work. have kind of idea why? i'm stumped this.

note: thought i'd post had gotten html down to.

<html> <head> <title>test</title> </head> <body> <table border='1' cellspacing='0' cellpadding='0'><tbody> <tr><td>this test</td></tr> {copyright} </tbody></table> </body> </html>

that boiled test case down to.

also note : did work. don't know why had put in break statement , put in on whim. thinking went "maybe there making re-evaluate string after change? let me try putting in break statement." did , - worked. have no idea why worked.

maybe i'm missing here doesn't seem need regex's here. str_replace function, http://php.net/str_replace, should work fine this.

example:

$string = "<html> <head> <title>test</title> </head> <body> <table border='1' cellspacing='0' cellpadding='0'><tbody> <tr><td>this test</td></tr> {copyright} </tbody></table> </body> </html>"; $copyright = '<tr><td>copyright 2007-now mycompany.  rights reserved.</td></tr>'; echo str_replace('{copyright}', $copyright, $string);

output:

<html> <head> <title>test</title> </head> <body> <table border='1' cellspacing='0' cellpadding='0'><tbody> <tr><td>this test</td></tr> <tr><td>copyright 2007-now mycompany.  rights reserved.</td></tr> </tbody></table> </body> </html>

update per comment:

$string = "<html> <head> <title>test</title> </head> <body> <table border='1' cellspacing='0' cellpadding='0'><tbody> <tr><td>this test</td></tr> {copyright} </tbody></table> </body> </html>"; $copyright = '<tr><td>copyright 2007-now mycompany.  rights reserved.</td></tr>'; foreach(explode("\n", $string) $line) {     echo str_replace('{copyright}', $copyright, $line) . "\n"; }

output:

<html> <head> <title>test</title> </head> <body> <table border='1' cellspacing='0' cellpadding='0'><tbody> <tr><td>this test</td></tr> <tr><td>copyright 2007-now mycompany.  rights reserved.</td></tr> </tbody></table> </body> </html>
