Removing words in a string

Hi

I want to remove words that end with : within a string.

For example if I write "test: 1234" it will remove "test:" and only echo " 1234"

Can anyone help me with this?

Thanks in advance

 

Preg_replace version:

preg_replace('/([a-zA-Z]*):/','',$str);

PHP:

or if you preference the old fashioned, explode way:

$str="test: 1234";
$final=array();
$str=explode(' ', $str);
$n=count($str);
for ($i=0; $i<$n;$i++)
	if (strpos($str[$i], ':')===false)
		$final[]=$str[$i];
$clean_string=implode(' ', $final);
echo $clean_string;

PHP:

 

Thanks alot!

 

Using this:

preg_replace('/([a-zA-Z]*):/','',$str);

PHP:

How can I make it replace if it is "test:" and if it is "test :" (with a space between the word and semicolon) ?

Thanks in advance

 

This works with both test: and test :

preg_replace('/([a-zA-Z]*(\s){0,1}):/','',$str);

PHP:

 

Thanks alot

Just one final question .. How can I make that code inverted? So it removes any word AFTER the semicolons?

You can use str_replace() function to remove particular string from the string, you can replace with blank space and you can remove string
