I want replace php codes in string and running fro server
$x = 1;
$string = "OK:{first}Yes{second}No";
I want replace if($x == 1){ to {first} and } else { to {second}
After run and echo $string , I want result in html :
OK:Yes
How did you come up with this approach? Why not simply:
$string = $x == 1 ? 'OK:Yes' : 'OK:No';
That would get you the string you want based on the value of $x.
Also if you literally mean that you want to do a search-n-replace on the PHP code itself (as #OllyTenerife assumes), then are you going to write it into a file to be executed later, or use eval() or something? Doesn't sound like the right track there... In which case, remodel your code.
$string = str_replace("{first}","if($x == 1)",$string);
$string = str_replace("{second}","} else {",$string);

I want to replace two words in a sentence with one word, like in the following example:
Kippa's luck was very bad yesterday.
I want to change it to:
Kippa's was very misfortune yesterday.
In this example, I know it has no sense, but it's just an example,
I want to replace (luck & bad) with the word (misfortune) in php.
Thank you
You can pass arrays as parameters to str_replace
<?php
$youText = "Kippa's luck was very bad yesterday.";
$replace_1 = ["bad", "luck"];
$replace_2 = ["misfortune", ""];
$result = str_replace($replace_1, $replace_2, $youText);
echo $result;
?>
Thank you. but actually there are alot of different words to be changed with, not only one word. I need something like this: **
$URLContent = "he has a bad luck. but he is ok, a good man";
$remove_multi = array(['bad', 'luck'],
['good', 'man']);
$replace_multi = array(['misfortune', ''],
['nice', '']);
$URLContent = str_replace($remove_multi, $replace_multi, $URLContent);

I have a array of random generated strings looking like this:
63njpn5u
byrtg1za
ht6wnz39
em1yyrju
2ytoxfxl
n5kaho14
zg92pg4n
gr9e7i01
u3t07ai4
I need a php code that will cycle trough these and output the ones back that contain one number. So in the example above I would've gotten back:
2ytoxfxl
em1yyrju
byrtg1za
I've tried using preg_match_all but I cant figure out how to use this with a array.
What you need is preg_grep:
print_r(preg_grep('/^\D*\d\D*$/', $your_array));
You can count like using string method :
$string = "2ytoxfx3l";
echo $int = strlen(intval(preg_replace('/[^0-9]+/', '', $string), 10));
Group of element:
$string = array( "63njpn5u","byrtg1za","ht6wnz39");
foreach($string as $str){
echo strlen(intval(preg_replace('/[^0-9]+/', '', $str), 10));
}

I have html code loaded in array $gh[0] and i am coonverting it to plain text
if i compare with same text loaded into new variable it doesn't works
can someone help with the issue, what should be exact value in $a to match the content in $gh[0]
i want comparsion to be working , what will be output if $gh[0] is converted into plain text especially line break
<?php
$gh[0]="Net inventory (used in)/from<br>Production Activities"
$fg=$gh[0]->plaintext;
$a="Net inventory (used in)/from Production Activities"
if($a == $fg)
{
echo "match";
}
else
{
echo "No match";
}
?>
What about just stripping all elements from the input?
$gh[0]= strip_tags($gh[0]);
If you want to know what the value (of $fg) is, why don't you check it?
There's echo, print_r and var_dump.

I attempted encoding a '=' symbol to its html equivalent through the use of:
htmlentities("This is my test and it = this");
The result is:
<p>This is my test and it = this</p>1
Notice how the equals sign is not encoded? I know there is a HTML equivalent.
What is an alternative function I can use to encode this string?
Thanks.
I know there is a HTML equivalent
The equals sign isn't encoded for HTML, there is no reason to do so.
You might be thinking of URL-encoding, which would be %3d:
urlencode("This is my test and it = this");
// => "This+is+my+test+and+it+%3D+this"
There's no need to encode the =; it's HTML-safe. If you really want to, though: =
echo str_replace('=', '=', htmlentities("This is my test and it = this"));

I was wondering if you could give two values to a class and then acces to the second one by POST, something like this (part of the code):
echo "<select name='selecttsk' id='selecttsk'>";
while($w = $bd->obtener_fila($tasker, 0)){
echo "<option class='opcion1' value ='".$w[1]/$w[2]."'>".$w[0]."</option>";
}
echo "</select>";
?>
and then i need to do something like this in other file
$var = $_POST[selecttsk];
but i need $w[2]
thanks
I suppose your $_POST['selecttsk'] does have the values in the following format:
"foo/bar"
You could use "explode" in PHP to get the second part (bar), for example:
$postvar = $_POST['selecttsk'];
$vars = explode("/", $postvar);
// Then
$var = $vars[1]; // Will be the $w[2] from the form
Look into: http://php.net/explode
Beware that if $w[1] or $w[2] ever contains a "/" you might get unexpected results, you could use the limit function of explode to mitigate that issue.
However - I would generally not recommend this workflow.
Why do you need to send two variables with one select?
(could you show us som example of what $w contains)
