preg_replace with a " as replace

[mort]

Hey peeps

 

Am trying to turn an HTML file into a string (will use file_get_contents()), and then turn all of the "s into \"s so that I can echo the string.

 

Having problems with what to put in the pattern and what t put in replace

 

I have

$file = file_get_contents("file.html");
$pattern = "\"";
$replacement = "\\\"";
echo preg_replace($pattern, $replacement, $file);

I don't get an output at all, anyone tell me *** i'm doing wrong? Its probably something simple lol  :cool:

You don't want to do that at all, what you want to do is use the htmlentities() function with the "ENT_QUOTES" option:

<?php
$file = file_get_contents("file.html");
echo htmlentities($file,ENT_QUOTES);
?>

ahh cool

 

can i use that to literally \ each " and then output it as \"?

 

as I want to edit the code, stick variables in, and have it all as one massive concatinated string like so

 

echo "<tr>"
."<td background=\"$images_dir/index_04.gif\" width=\"562\" height=\"628\" alt=\"News\" valign=\"top\"><a name=\"news\"></a></td>"
."</tr>"
."<tr>"
."<td background=\"$images_dir/index_05.gif\" width=\"562\" height=\"361\" alt=\"Technical Info\" valign=\"top\"><a name=\"tech\"></a></td>"
."</tr>"
."<tr>"
."<td background=\"$images_dir/index_06.gif\" width=\"562\" height=\"913\" alt=\"Dealer Spotlight\" valign=\"top\"><a name=\"dealer\"></a></td>"
."</tr>";

 

So rather than manually replacing each " with \", I wanted to make a script to do it for me

The function htmlentities() does not escape quotes, it converts them to the HTML Entity form like " so when they are echoed to the screen they look correct.

 

If you want to escape the quotes, use the addslashes() function.

i always try to over complicate things, i use addslashes() all the time so dont know why I didnt think of it
