[SOLVED] str_replace

[the-botman]

ok hi guys ...

 

i am not sure if i am posting my question in the rite place but here goes.

i want to str_replace all numbers between 0-60 and change the colour of the numbers this is what i have and it works but using this way i need to have 60 lines of code is a any other way?

 

$Fguide = str_replace('0','<font face="Verdana" color="red" size="2">0</font>',$Fguide);

[premiso]

$i=0; 
$upper = 60;

while ($i <= $upper) {
    $Fguide = str_replace($i, '<font face="Verdana" color="red" size="2">' . $i . '</font>', $Fguide);
    $i++;
}

 

A simple while loop does wonders for ya

Hmm that gives me a TON of information to help you out....if it is not working either:

 

A. You omitted a good chunk of code, post that here so it can be tailored a bit more.

B. See A.

i am sorry i am very new to php , ok see i am pulling the tv guide from a site to mine it displays like this http://bhawap.com/TvGuide-sabc1.php and your code works but only if u change it to

$i=2; 
$upper = 60;

while ($i <= $upper) {
    $FGuide = str_replace($i, '<font face="Verdana" color="red" size="2">' . $i . '</font>', $FGuide);
    $i++;
}

will look like http://bhawap.com/TvGuide-etv.php but if i add it the way u show me will display like http://bhawap.com/TvGuide-sabc2.php

if u want i can paste my whole code i just did not want to flood this section and i am sorry for any mistake in my questions

You are placing EVERY number from 0 to 60.. so the results your getting are correct..

also $i should be 0

 

I think you want to limit your replacement,

ie every quoted number ie "0"

That's just an example

You want the reason, because after you iterate it up passed 0 and 1 it replaces 2 which there are "2"'s that are inside the tags, the flaw is that there are tags in the code and of course if a tag is created within a tag it will cause issues:

 

<font face="Verdana" color="red" size="<font face="Verdana" color="red" size="2">2</font>">0</font>	

 

Notice how it is replacing the 2 inside the <font> tag, which of course will cause display issues.

 

The code I provided works, it is just that since the code replaced has a 2 in it, causes a little issue that anything replaced before that will be replaced.

 

A better method of doing this, use a CSS style so you do not get this error.

 

<style type="text/css">
.redColor {
    color: red;
    font-size: 15px;
    font-family: Verdana;
}
</style>

<?php
$i=0; 
$upper = 60;

while ($i <= $upper) {
    $FGuide = str_replace($i, '<font style="redColor">' . $i . '</font>', $FGuide);
    $i++;
}
?>

 

Will solve that problem.

 

EDIT: I should have caught that ahead of time, sorry for that.
