PHP str.replace: two or more at one time?

Question

let's say I have a string like this:

$str = "{aaa,aa,a,aaaaaaaa,aaaaaaa,aaaaaaa}";

I want to remove both { & } using str_replace only once.. Possible?

I've tried

$str = str_replace ('}', '{', '', $str);

$str = str_replace ('}'&'{', '', $str);

$str = str_replace ('}'||'{', '', $str);

$str = str_replace ('}''{', '', $str);

and none works...

Just a side note, you might want `trim($input, '{}');` if you only want to remove the left and right sides, it's a little shorter and more to the point. What *is* the data? — Wesley Murch, May 11 '12 at 04:59

$str = str_replace(array('}', '{'), '', $str);

str_replace accepts arrays as its first and second argument

you can give an array to str replace see

$search = array("}", "{");
$text= str_replace($search, "", $text);

What you want to do is use the preg_replace function instead which will replace more than one item at a time using regex. What you want to do can be accomplished with:

$str = preg_replace('/({|})/', '', $str);

Or `[{}]` which is slightly better – zerkms May 11 '12 at 07:41

$search = array("}", "{"); $text= str_replace($search, "", $text);

yuo can read more :- http://php.net/manual/en/function.str-replace.php

example

<?php
// Order of replacement
$str     = "Line 1\nLine 2\rLine 3\r\nLine 4\n";
$order   = array("\r\n", "\n", "\r");
$replace = '<br />';

// Processes \r\n's first so they aren't converted twice.
$newstr = str_replace($order, $replace, $str);

// Outputs F because A is replaced with B, then B is replaced with C, and so on...
// Finally E is replaced with F, because of left to right replacements.
$search  = array('A', 'B', 'C', 'D', 'E');
$replace = array('B', 'C', 'D', 'E', 'F');
$subject = 'A';
echo str_replace($search, $replace, $subject);

 // Outputs: apearpearle pear
// For the same reason mentioned above
$letters = array('a', 'p');
$fruit   = array('apple', 'pear');
$text    = 'a p';
$output  = str_replace($letters, $fruit, $text);
echo $output;
?>
