使用带有PHP的正则表达式替换文本

Question

I have a string that is something like "apple|banana|peach|cherry".

How can I use regular expressions to search this list and replace another string with a certain value if there is a match?

For example:

$input = 'There is an apple tree.';

Change that to: "There is an <fruit>apple</fruit> tree."

Thanks, Amanda

Answer 1

preg_replace function

Although, if you want to match directly, it's faster to use str_replace or str_ireplace like that:

$text = "some apple text";
$fruits = explode("|", "apple|orange|peach");
$replace = array('replace apple', 'replace orange', 'replace peach');

$new = str_replace($fruits, $replace, $text);
