PHP - Replacing A Semicolon In A String

How come this is not replacing correctly?

$rp = strtr($rp,"[TIMES]","<span style='font-family: Times New Roman, Times, serif'>")

I want to be able to replace, let's say, every fifth letter from a string.

The string is unknown, though, it could come from database, or a POST form. So I'm unsure if I could use str_replace.

I think I may need to use preg_replace(), but I'm not not sure.

Hi

I am trying to replace characters in a string with images so character 'a' will be replaced with a.jpg etc  I have tried the following code but that doesn't result in the desired effect as the updated string gets it's characters replaced as the script works through it so the 'img' in the first updated string gets replaced with with images and it all ends up quite a mess.  Is there a simpler way to do this?

$content = "abc" ;
$content = str_replace("a", "<img src=images/a.jpg >", $content);
$content = str_replace("b", "<img src=images/b.jpg >", $content);
$content = str_replace("c", "<img src=images/c.jpg >", $content);
$content = str_replace("d", "<img src=images/d.jpg >", $content);
$content = str_replace("e", "<img src=images/e.jpg >", $content);
$content = str_replace("f", "<img src=images/f.jpg >", $content);
$content = str_replace("g", "<img src=images/g.jpg >", $content);
$content = str_replace("h", "<img src=images/h.jpg >", $content);
$content = str_replace("i", "<img src=images/i.jpg >", $content);
$content = str_replace("j", "<img src=images/j.jpg >", $content);
$content = str_replace("k", "<img src=images/k.jpg >", $content);
$content = str_replace("l", "<img src=images/l.jpg >", $content);
$content = str_replace("m", "<img src=images/m.jpg >", $content);
$content = str_replace("n", "<img src=images/n.jpg >", $content);
$content = str_replace("o", "<img src=images/o.jpg >", $content);
$content = str_replace("p", "<img src=images/p.jpg >", $content);
$content = str_replace("q", "<img src=images/q.jpg >", $content);
$content = str_replace("r", "<img src=images/r.jpg >", $content);
$content = str_replace("s", "<img src=images/s.jpg >", $content);
$content = str_replace("t", "<img src=images/t.jpg >", $content);
$content = str_replace("u", "<img src=images/u.jpg >", $content);
$content = str_replace("v", "<img src=images/v.jpg >", $content);
$content = str_replace("w", "<img src=images/w.jpg >", $content);
$content = str_replace("x", "<img src=images/x.jpg >", $content);
$content = str_replace("y", "<img src=images/y.jpg >", $content);
$content = str_replace("z", "<img src=images/z.jpg >", $content);


echo $content ;

Any help would be gratefully appreciated.

Hey guys.  So I'm trying to write a script that replaces footnote citations in one format with footnote citations in another format.

For example, the text will read:   "Then he went down the street.[1] That is where the police found him [2].  They immediately arrested him at the house. [3]"

And I would like the script to find the [ #] strings and replace them with {#} ... so that the string reads:
"Then he went down the street.{1} That is where the police found him {2}.  They immediately arrested him at the house. {3}"

Note that there will be double, and even tripple, digit footnotes, so the script has to be able to recognize [##] or [###] and replace the brackets with {} accordingly.

I'm not really sure how to do this, since the "pattern" is constantly changing depending on the number between the brackets.  Ideas?

Thanks!

Hi, I'm a beginner just learning PHP right now, so my question is probably a simple one but I can't seem to figure this out.

I'm trying to code the following if/else statement. When I've tested the code, the echo "Value is not a number" is appearing as if it were not part of the if/else statement. Is it not working because of the semicolon at the end of the first echo statement? Or am I missing another set of curly braces? I'm not sure how to approach this . . .



<?php

for ($row=1; $row<5; $row++)

{
    $value_of_amount = $_POST['value_of_amount'];

    if (is_numeric($value_of_amount))
    {
     echo "<tr><td> $value_of_amount </td>";
    } else {
     echo "<tr><td> Value is not a number </td>";
    }
}
?>
