Ограничаване на символите

[montana]

Как ще стане така че това в червения цвят да извежда примерно само 50 символа ?

{
$var = substr($echo_text['post_text'] , 0 , 60);
$var
}

Замести го с това.

Грешка:

Parse error: syntax error, unexpected T_ENCAPSED_AND_WHITESPACE, expecting T_STRING or T_VARIABLE or T_NUM_STRING in E:\VertrigoServ\www\news.php on line 170

ред 170: $var = substr($echo_text['post_text'] , 0 , 60);

 

[tedo96]

Пробвай така:

{
$var = substr($echo_text['post_text'] , 0 , 60);
$var;
}

или така:

{
$var = substr($echo_text[post_text] , 0 , 60)
$var
}

 

[montana]

С този код ми изкарва така:
{ = substr( текста ала бала , 0 , 60) ; }

{
$var = substr($echo_text[post_text] , 0 , 60)
$var
}

А и виж как е оцветех кода:

 

[tedo96]

Направи гоа така:

".{
$var = substr($echo_text[post_text] , 0 , 60)
$var
}."

Тези echo с html и какво ли не вътре най-много ги мразя...

 

[montana]

Parse error: syntax error, unexpected '{' in E:\VertrigoServ\www\news.php  on line 169

ето го реда

Тц...

?>
<?php	
{
$var = substr($echo_text[post_text] , 0 , 60);
echo $var;
}
?>

За мен е по-лесно като започна с html ако е по-голямо количество просто да си излезна от php-то. Най-вероятно сега пак няма да стане и ще трябва да го преработиш и на горе. Говоря за смесването на html и php.

Пак нищо... някакъв друг начин няма ли ?
