POReplace certain content in txt file and save it using PHP?
text
Body
copied!<p>So I receive variable replace it in certain area in txt file and save it back. I get page number and according to it I get exploded data. Anyway I'll post a code below to make it more clear: </p> <pre><code>$pgnm = $_GET['page']; //This is the page number as I've said. $conts = file_get_contents("content.txt"); </code></pre> <p>the content of content.txt looks like this:</p> <pre><code>text1|text2|text3 </code></pre> <p>I display this content in certain pages. For example on first page: text1, on second text2, etc.</p> <p>Now i'm working on a form where I successfully change these. I get as I've said page number and text:</p> <pre><code>$text = "new text"; //this is the content which I want to be replaced instead of text2. </code></pre> <p>I make the content.txt file look like this after its saved: text1|new text|text2</p> <p>So lets go on:</p> <pre><code>$exp = explode("|", $conts); //this explodes data into slashes. $rep = str_replace($exp[$pgnm], $text, $conts); file_put_contents("content.txt", $rep); // Saving file </code></pre> <p>All these above-mentioned operations work perfectly, but here's my problem now. This only works if content.txt has certain content, if it's empty it enters my new text and that's all: 'new text' and that's all. Maybe I want to add second page content 'new text2' and after I finish entering it and save I want the file to be displayed like this: new text|new text2. If the content of content.txt looks like this: 'new text|' str_replace doesn't replace empty string. So that's my another problem too.</p> <p>I tried everything, but couldn't manage to anything about this two problems. Thank you in advance for your help!</p>
