[SOLVED] Converting number to string

[harishkumar09]

How to convert a number to a string ? I want to create a new string by concatenating a string and a number.How to do it ?

 

The scenario is the user selects the gallery he wishes to see.And I construct the filename which contains links to images by concatenating a standard string "file" and the number he has chosen say "4" to create

"file4.txt" and assign it to a variable $myfile and then open the relevant file and then display the list of images contained in it. Can anybody help ?

just typecast it

$yourNumber=999;

$numberInString=(string)$yourNumber;

$numberInString=(string)$yourNumber;

 

Thank you.But I didnt know there were variable types in PHP. I tried just concatenating a string variable and interger variable and assigned it to a string and it accepted it and was successful. I could do what I wanted.

But thanks anyway.

Yes, PHP is very loose with variable types. Typecasting can come in handy, but for the most part it isn't necessary.

You really don't need typecasting for this. Just put the number in the concatenation...

 

 

<?php
$n = 4;
$myFile = 'file'.$n.'.txt';
//or
$myFile = "file{$n}.txt";
?>
