I have a string. I want to write a script in PHP for return a string if it has specific characters.
For example: "Hi, this is the sample.png" is a string. Now I want to output as "Hi, this is the".
I.e., if the string contains .jpg, .png, then I need to replace those words from a string.
This is my sample code:
$output = preg_replace('/.png/', '$1','Hi, this is the sample.png');
The solution using
preg_replace function with a specific regex pattern:
$str = 'Hi, this is the sample_test.png (or, perhaps, sample_test.jpg)'; $output = preg_replace('/\b[\w_]+\.(png|jpg)\b/', '', $str); print_r($output); // "Hi, this is the (or, perhaps, )"
If you suppose some other characters to be a part of the "crucial words" - just add them into a character class
[\w_ <other characters>]
