I have this code:
elseif($pagina == "agenda")
{
$html = file_get_contents("template/index.php");
$html = str_replace("%content%",file_get_contents("template/agenda.php"),$html);
$html = str_replace("%current2%",'class="current"',$html);
$html = str_replace("%sidebar%",file_get_contents("template/sidebar/sidebar_nieuws.php"),$html);
}
On the page "agenda.php" is a normal php script. This does work when I open agenda.php directly, but when I open it with this code, the code doesn't work. I think file_get_contents doesn't work on php? What is an alternative?
(Sorry for my bad english ;)..)
I would use output buffering. It's effective in this kind of scenario.
$html = file_get_contents("template/index.php");
$arr = array();
ob_start();
include_once('template/agenda.php');
$file = ob_get_contents(); //$file now stores the rendered output (after PHP has run) of template/agenda.php
ob_end_clean();
$arr['agenda'] = $file;
$html = str_replace("%content%", $arr['agenda'], $html);
if you want to run the php code. Then you can include your php file:
include('path/to/file.php');
if you want to change php code from file before executing then in the end run eval($html);

I have this little function to stop a string being too long but it dosen't seem to work. I'm assuming i've done something wrong?
function trimString($string, $maxChar) {
$string = (strlen($string) > $maxChar) ? substr($string,0,$maxChar).'...' : $string;
}
I was using it like this:
echo trimString($row['mainTitle'], 30);
Thanks
You forgot to return value from function. Try
function trimString($string, $maxChar) {
return (strlen($string) > $maxChar) ? substr($string,0,$maxChar).'...' : $string;
}

$z = file_get_contents("vars.txt");
var_dump($z);
This is my current code. When I run it I see this output:
string(0) ""
I am not sure why - this file contains 321 characters. It is in the same directory with my PHP script. Can you explain me reasons, why that doesn't work? Writing to this file works ok (with "w+" mode).
I though this is chmod mistake, but I wrote chmod 777 dir command, and still doesn't work.
Full code of my script is there: https://gist.github.com/ty221/274bda4ecec03f710691
Displaying all errors E_ALL doesn't work - I mean nothing is getting displayed.
How about reading the manual: http://php.net/manual/en/function.fopen.php
And a quote from there:
'w+' Open for reading and writing; place the file pointer at the beginning of the file and truncate the file to zero length. If the file does not exist, attempt to create it.
^^^^^^^^^^^
That means with your line:
//Deletes all content in the file
$file = fopen("vars.txt", "w+");
$to_save = "";
//Reads the content from a empty file
$z = file_get_contents("vars.txt");
//Outputs an empty string
var_dump($z);

I'm currently having an issue with simplexml_load_file(); my xml path is a url, that is rendered as a variable
$xurl = "domain/pathto/myfile.xml"; // This is actually a variable that returns the entire URL to where my xml file is -- this will change from file to file
$xmlpath = parse_url($xurl, PHP_URL_PATH); // to get the path of my xml file ex. /pathto/myfile.xml
$xmlpath = mb_substr($xmlpath, 1); // returns pathto/myfile.xml
here is where my problem is, when I put it into :
simplexml_load_file($xmlpath);
In my function, I get nothing appearing from the XML file
However, in my same function if I change it to
simplexml_load_file("pathto/myfile.xml");
My function works fine.
I did an echo on $xmlpath and it returns the pathto/myfile.xml just fine.
<?php echo $xmlpath; ?> // returns pathto/myfile.xml
What am I doing wrong?
EDIT: Phil
echo strcmp("pathto/myfile.xml", $xmlpath)
returns a 0.

Have code:
$url = 'http://www.domain.com/dir1/dir2/dir3/page-2.html';
if ($strpos = strpos('/page', $url)) echo '1';
else echo '2';
It shows only '2'.
How can I fix it?
Change arguments places
strpos($url, '/page')
strpos
Actually the syntax for function was mismatched I think.
use this
$stropos = stripos($url,"/page");
echo $strpos;
Please add === identical compare in if condition and correct the position of strpos parameters
$url = 'http://www.domain.com/dir1/dir2/dir3/page-2.html';
if ($strpos == strpos($url, '/page')) echo '1';
else echo '2';
