I have a task to find and replace words starting and ending with "#".
Example - my string will look like:
Put your hands up in the air for #performer1# , Put your hands up in the air for #event#.
What I expect as a output is:
Put your hands up in the air for #performer1# , Put your hands up in the air for #event#.
I have no idea about regular expressions in php, and I'm a beginner, can someone help?
As you already suggested, the preg_replace function should do the trick. What you now need is a regular expression like this
$string = "Put your hands up in the air for #performer#, ...";
$pattern = "/#(\w+)#/";
$replacement = '<strong>$1</strong>';
$new_string = preg_replace($pattern, $replacement, $string);
The magic bit is the $pattern variable where you specify what to look for. If you put parenthesis around something, you can reference the actual contents in the $replacement variable.
The \w+ basically says: match as many characters as possible (and at least one) that are either a-z, A-Z, 0-9 or _.
The PHP PCRE Pattern Syntax can give you some more hints about how to use regular expressions.
